This board offers a small footprint and headers for convenient use in breadboard, or directly, a micro USB socket , automatic download / debug / Log abilities thanks to the new high USB-UART bridge from Silicon Labs CH340G. An automatic reset circuit makes programming with Arduino and others IDE a breeze. PCB layout a been well optimized in its current 4.0 version, all IOs are broken out. The board has it own onboard 3.3V LDO, two keys and two LEDs. Reduced footprint of 61.6 x 17.7 mm (2428x700mil).

Features:

• ESP32 240MHz
• Onboard 3.3V LDO regulator
• CH340G USB UART bridge
• Onboard reset circuit for auto programming
• Flash size is 16M

Note: The pin out names might not be the same. But the function of the pins are the same.
