This Widora-air development board is the perfect platform to use this ESP32. It offers fingerprint and header csamll for convenient use on bread plate, or directly, a micro USB plug, automatic discharge / debug capabilities / Log thanks to the new USB-UART High Bridge from Silicon Labs CP2104. An automatic restart circuit makes programming with Arduino and other IDE a breeze. PCB design has been well optimized in its current version 4.0, all the IOs are broken. The plate has its own 3.3 V LDO, two keys and two LEDs.Low footprint of 61.6x17.7mm (2428x700mil).
