excellent overview many thx btw.. i wish i have ur soldering skills u make it look so easy

Wow, i loved this board. Congratulations to for this video.

I put one of these to work as an ARGB controller. It's absolutely capable and can directly control WS2812b LEDs without a logic level converter. It can also directly power WS2812b LEDs from its 5v pin as long as you are only lighting a handful of pixels. I only have one complaint / request: Can you guys maybe make a version that supports power delivery negotiation for the 5v/vcc output pin? I couldn't find any documentation on what the maximum output current is on the 5v pin. Looking at the circuit diagram, it appears the XIAO only uses the USB 2.0 protocol and the 5v pin is guarded by a diode with a 500ma limit. With PD negotiation, you could potentially output several amps over the 5v pin, allowing you to drive long strings of LEDs without an external power supply. I do realize that implementing PD would be a substantial redesign, but you've got Bluetooth variants so PD sounds like the next big thing :)

Any touch pins?I think the esp32 chip crushes this.no usb not a big deal. We all have arduino unos somewhere in our house to configure the esp32 chip.

Sir, Above will be compatible for "Tasmota"?

Hi does anyone know where to get that charger to connect seeduino to laptop

You didn't give the line to put into arduino preferences.

There is No EEPROM, is there a way to save data before power down on this controller ?

Its not an Arduino its nothing to do with Arduino its just another China item
