Recently, Arduino released four new products. They all look very similar but use completely different Microcontroller chips. So we have to answer two questions: Do they know what they are doing and is it any good for us Makers? And of course: How do they compare with the ESP32?
In this video, we will look at these four boards:
- Arduino Nano Every
- Arduino Nano 33 IoT
- Arduino Nano 33 BLE
- Arduino Nano 33 BLE Sense
And look into the following topics:
- An overview of their capabilities. We will also add a typical ESP32 board for reference
- We will have a look into how the Arduino IDE supports a multi-CPU Architecture environment
- We will look at the new 3.3-volt world and the dangers coming from this change
- Will find out bad things about the boards if they exist
- We will test the BLE and Wi-Fi functions and measure power consumption
- And we will try to answer the essential questions: What are the implications for the future of the Arduino platform. And: Is there a new star born?

I keep 3.3V and 3.6V zener diodes on hand to limit voltage to the 3.3V side of communications. A small 100/68 ohm resistor is placed on the 5V side, then a zener to ground directly after.
@hamjudo
@hamjudo 4 роки тому
If I did my math right, when the 5v side pulls the line high, 68 ohm/3.3v zener circuit will draw 25 mA. That is 125 milliwatts per I/O pin. That could dramatically reduce the run time with a small battery. At high frequencies (500 kbaud) and with a lot of capacitance (breadboard), it may require a relatively low value resistor on the order of 330 ohms. At lower data rates (9600 baud) or lower capacitance (PCB), 10kohms or even higher should be sufficient.
@GnuReligion
@GnuReligion 4 роки тому
​@@hamjudo Cannot argue with your math. You are paying attention! I was concerned with such a low value resistor (that I did not have) the first time seeing this requirement for a zener clamp. Higher valued resistors have worked for my purposes, but "68 ohm" is most often cited to drop that 1.7V. There is an "Iz(min) minimum current required for the diode to break down" that may be as high as than 10mA. You can try putting 10k in series with a zener on a breadboard at 5V. Do you read 3.3V? It is much higher (have tried). If you look up schematics for the V-USB project, you will find a lot of discussion about the best way to skin this cat. A couple of silicon diode drops, level shifters, resistor dividers, isolation circuits, etc. Zener clamps have worked for me on the rPi's MISO and RX pins. I use a double Mosfet level shifter for i2c. vusb.wikidot.com/local--files/hardware/level-conversion-with-zener.gif

I'd just like to suggest PlarformIO as an alternative to the Arduino IDE. I use it with VSCode, but it can be used with other IDEs/Editors, too. It comes with a library manager and allows multiple configurations for different boards in the same project. And most important for me: Using VSCode gives you reasonable code navigation and completion features.

The Arduino "IDE" is an insult to real IDEs. I wish they would work on that instead of creating new boards. Mostly for the benefit of people who are getting into this now and don't know any better.

@SianaGearz
@SianaGearz 4 роки тому
BLE cannot do audio full stop, for numerous reasons. It's too slow, it only supports short messages and has forced airtime gaps, the SFP and A2DP profiles are not defined. Then again your own protocol with some kind of highly predictive coding... i can remember there was some kind of just about intelligible speech codec that was developed by ham radio enthusiasts but needs ridiculously little bandwidth. I'll get back here if i can remember what it was. Ah it was probably Codec2 which goes down to 460bit/s. You should have oodles more than that available via BLE, you could probably upgrade to SPEEX/Opus.

What I like about about this product line is that Arduino went back to their well established Nano form factor. It seems that MKR form factor didn't got as much popularity as Feather from Adafruit, but Nano can be a good alternative for projects not intended for battery operation. Moreover, Nano BLE is first Arduino board capable of running CircuitPython, although some additional work and tool is needed to flash it with different bootloader.
@AndreasSpiess
@AndreasSpiess 4 роки тому
I do not know what the deciding factors were. But from experience, sticking to standard formats usually is not a bad idea because it can create a Eco-System. So chosing hte feather format would also have been a good idea, I think.
@JanCiger
@JanCiger 4 роки тому
The nRF52 series are excellent but the Arduino support and libraries are utter crap, unfortunately. You still need the proprietary Nordic "softdevice" blob that actually implements all the BLE protocol stack. The problem is that the Arduino doesn't use the latest version of this, so you have to deal with old bugs and missing features that are not present in the official SDK. On top of that, the Arduino side is buggy, unreliable and many BLE features are not supported. Oh and the power consumption is nuts. I have bought an EBYTES module from China for about $5, as described in the video. Get a CMSIS-DAP or JLink dongle and use the Nordic SDK directly (it is excellent, btw). You will get much much better results, with much fewer issues and power consumption down in about 4mA when running BLE and uA when sleeping.

@@AndreasSpiess Yeh, I guess they are too expensive and too new so that many of the examples are not fully working. I have found out how to load Nordic examples on the Nano 33, which does give users more options. Perhaps use the cheap Nordic hardware for most situations and the Nano 33 BLE sense for specific sensor apps. for link google "Topic: How to upload Nordic compiled .hex file to a Nano 33 BLE (Read 108 times)" It actually loads a nordic .bin file and I bricked my nano because I missed the memory step .

Beside the normal power consumption I would be interested in numbers regarding deep sleep. The IoT version has a Cortex M0 processor so I had expected that it has an I2S interface, so I'm a bit surprised that in your table is a "no". Had someone a deeper look at this and can confirm that I2S is not possible with the Arduino nano 33 IoT?

Cost. Sell 1 model and have 1 factory and buy 1 million parts at a time. Have 20 product lines? 20 factory lines minimum, have huge inventory space (because some might not sell for a while, and if you change production lines and get a massive order you won’t have time to fulfil). Retooling as those components are in no way the same shape and some might be picked up by vacuum while others may need robotic arms and hands of various sizes or a simple PNP machine), then solder order (can’t just heat-gun it all now if there is some plastic coin battery box if it melts, WiFi chips might be more susceptible to damage if it’s too hot so then you gotta change your temps and duration), then it also gets cluttered picking an item (“mom I want an Arduino for my birthday”, “ok, sweets, they have like 20, which one...”). Modular design (just like computers) has been a big thing for Arduino, it’s basically legos anyways, just like computers (pick a CPU and main board, pop it in just like a WiFi chip on Arduino, slot in ram just like a motor driver module, slide in an NVMe just like an SSD card reader, plug in a GPU or WiFi networking card just like a WiFi module, pick your power supply just like Arduino, it’s all basically the same thing). I think the modular way is probably just as cheap as integrated to due to above logistic and manufacturing issues, plus for $2 you can make it entirely different purpose in the future. If you didn’t know, you just buy whatever computer parts you want, like my machine has: TR-1950x CPU 4x R9 Fury GPUs 4x 8GB 3600 memory 2x SuperNova 1300 PSUs NVME SSD, RGB SATA SSD, mechanical HDD Water cooling with multiple radiators 3x 4k monitors plus a 240Hz 1080p monitor And if I feel like it I can also add more: for rendering videos while I games I’ve used a Titan Xp for CUDA acceleration plus 3x RX470 for open GL compute while I did some 4k gaming on 2x R9 Fury crossfire, all on the same PC, 6 GPUs of mixed graphics for specific tasks all at once, just like Arduino modules can be combined. So it’s very similar with the old modular designs as computers are, they already have that.

I wrote a WiFi SSL application for the Nano33 IOT board 2 years ago. I wanted to duplicate the project for a few friends, so I ordered the latest boards from Arduino. The code connected to WiFi OK but would not do an SSL connect to a remote server. Upon investigation, I found the Nano33 microcode level on my original working boards was 1.2.3, and that of the latest boards that would not work is 1.4.8. It looks like changes made to the firmware broke the SSL connect feature. I opened a problem ticket with Arduino, but they never acknowledged the problem. Desperate, I tried to downgrade the microcode to the earliest code I could find (version 1.2.4), but SSL connect was not functional there either. Do you know any way I can get version 1.2.3 of the microcode loaded into the Nano33 boards so I can do SSL connects that will work in my Arduino sketch?

Always awesome videos. Bit dismissive on the Every however. Faster, more memory, 21v input tolerant and about 40% cheaper than the Nano, 50% in the 6-pack. Not "every" project is IOT and the pricey 33's don't give you a simple nrf24 short range remote capabilities for non-wifi scenarios or LORA for that matter. Simplify development for automotive, farming, etc. no longer needing a buck converter to drop the 13.8-14.2 volts down. I applaud Arduino offering a new high quality board, more cost competitive with clones and drop in replacement for existing projects. It is my go to board for non IOT as it has longevity. No dispute it is largely a refresh after 13 years and Arduino must recognize the demand still exists. Just surprised you were a bit dismissive of it being an important revision to the Nano. Keep up the great videos and 73s!

When ever something new is happening, and I get a chance to look it over at a great price I act. Then, after receiving my "new" product, I begin to search for someone who can tell me what the heck I have in my grubby old fingers. In this case, I was searching EBAY for a deal on some NANO boards, I love their size and how handy they are for my ghost buster projects that I build for our local paranormal club. No I am not a member, just love to play with Arduino's and they work great at building devices that are supposed to find ghosts. So it was, I was searching and came across a deal with one of the new NANO 33's. Not knowing what it was, I bid anyhow because it came with a regular NANO and there were no other bids. Got the 2 NANO's for 10 bucks plus 3 shipping. Not bad for an honest to goodness Arduino NANO and the 33 BLE Sense. Well they came in the mail today and look as though the previous owner never even tried them out. I was very happy and then I began to try and figure out what I had. Of course your video always floats to the top of my searches in UKposts and I was very happy to see that because you always do such a great job with your presentations. Now I know what I have and am even happier. It's Christmas in July!! Now to figure out what to use the new one for, those sensors are right up the alley for ghost finding purposes.

In my quest for lower power consumption I fell into the world of ARM with Nordic chips a while ago.

So, in my incomplete (untested and possibly incorrect) opinion, we, as makers we now have access to the entire mbed software stack when using Arduino boards based on Nordic NRF5* chips.
