CH340G Pro Mini TTL USB - RS232 Converter Arduino
The module allows communication with with 3V3 or 5V logic systems. The selection of voltage on the TX and RX lines is made with a jumper, connecting the VCC pin to the 5V or 3.3V pin, respectively.
- CH340G chip
- LEDs: Power, TX, RX
- TX, RX, 3.3V, 5V, GND pins,
- works perfectly with our Arduino PRO MINI modules
