eflashy32 is a USB Type-C, CP2102N serial interface targeting ESP devices. It has a 500mA resettable fuse, ESD protection, and a switch to choose if you want to send 3.3V to the device or not. While ESP32 devices were the main goal, it can function just as any other USB to TTL UART converter.

This board can properly reset an ESP32 when using esptool (or other tools) for automatic reset into programming mode. It can supply up to 500mA of power at 3.3V to the target device as well!

The board is designed in a such a manner to allow either a 2.54mm pitch 1x6 pin header, 1.27mm pitch header, or pogo pins!
