Nice T-01C3 module. Tested in Arduino environment IDE 1.8.19, ESP32 package 2.0.2, board selected "ESP32C3 Dev Module". The module is pin compatible with ESP01 (based on ESP8266) and can be used on the same adapter for flashing/debugging code. But the GPIOs available on the connector are not the same between the 2 modules and a small adaptation is mandatory when porting software from ESP01 to T-01C3 GPIO 8,9 and 2 are available on the connector ( One more than on the ESP01) A green LED is on GPIO 3(it is on GPIO 2 on the ESP01) and It seems that GPIO 2 can't be used as output (TX) with the HardwareSerial library (jQuery111304962499406939068_1642168743121) This module seems more tolerant concerning the power supply than the ESP01/8266 Tested with an application involving web server, GPS, file system etc … Nice module, with a very small footprint. Perfect when the size is important. But others ESP32-C3 modules with USB interface and more GPIOs maybe better for development/evaluation and easier to use
