The ESP Controllers from Espressif are popular these days for IoT-based designs. The most popular ESP Boards are ESP8266-01 & ESP8266-12E/12F. These boards are the very popular amount makers, designers & IoT enthusiasts. The ready-made plug and play board is already available in the market. But the problem with these boards is they are very big in size and has power-hungry voltage regulators that may not be suitable for compact and low power projects.
This is why it is necessary to design your own ESP Board for Battery-Powered IoT Applications. In this tutorial, we will learn how to design a circuit and a compact PCB for using the ESP8266 controller. We will use the low-power LDO instead of voltage regulators & add some battery charging and battery management feature to the board.
We will not use any USB-to-UART chip like CP2102, rather we will program the device using external FTDI. By removing the extra chips and using the low-power LDOs will reduce the power consumption and makes the device small-sized. Thus the device can operate with a small Lithium-Ion Battery and charge either using USB or Solar Power. You can also use ESP8285 as an alternative and most of the points discussed here will still be the same. Watch this video till the end as it will be very very interesting.
