About The Project
AButton V3 is a WiFi connected push button based on EspressIF's ESP32-PICO-D4. The push button "boots up" AButton and send message to MQTT broker. It will go to sleep after work be done.
Additionally, the board includes a WS2812B RGB LED and buttons to aid in your development.

How To Programming Your Own Firmware
Use ESP Flasher To Program AButton
We designed pins 2 x 4 for match ESP Flasher. ESP Flasher is an USB to UART converter. It's best tool to program AButton. See the photo for how to wire it
Installing via Arduino IDE Boards Manager
Espressif has added support for the Arduino Boards Manager and by installing this way, you get the benefit of a slew of great built-in examples. Instructions for installing via the board manager can be found at espressif's arduino-esp32 GitHubopen in new window.
If you have successfully installed the ESP32 core to your Arduino IDE, you should see the following under Tools with the ESP32 Pico Kit selected:
