Simple implementation for a E32-TTL-100 ReceiveMsg/SendMsg with a Arduino Nano/UNO.
UNO/NANO(5V mode) | E32-TTL-100 | |
---|---|---|
D7 | <---------------------> | M0 |
D8 | <---------------------> | M1 |
A0 | <---------------------> | AUX |
D10(Rx) | <---> 4.7k Ohm <---> | Tx |
D11(Tx) | <---> 4.7k Ohm <---> | Rx |
need series a 4.7k Ohm resistor between Rx-Tx.
