ESP-01 and ESP-12 are widely used and most selling versions of ESP8266 chip.
I use ESP-01 for my small projects. I thought, it will be nice if I build a simple PCB widget, which will allow me to easily flash the latest firmware into ESP8266.
For this project, I simply integrated ESP-01 and ESP-12 footprint into single PCB [with RESET+FLASH buttons and GPIO options], in that way, one can add ESP module and flash the firmware with Zero errors.
There are going to be two versions of the tool..
- 3.3V Version
- 5V Version with LDO & logic level converter on RX-TX.
Designed in EAGLE Cadsoft tool. Double Layer. Small enough to sit at the corner of your bench.
