Wrong TX, RX connections in MEGA multi-serial connection schematic [MKC-554] #378
Description
On schematic on this page:
https://www.arduino.cc/en/Tutorial/BuiltInExamples/MultiSerialMega
The current connections connections are wrong:
| SERIAL ENABLED DEVICE | Arduino Mega |
|---|---|
| RX | RX1 |
| TX | TX1 |
They should be as follows:
| SERIAL ENABLED DEVICE | Arduino Mega |
|---|---|
| RX | TX1 |
| TX | RX1 |
The reason is because "RX" stands for "receive" and "TX" for "transmit". So the receiver pin must be connected to the transmitter pin, and vice versa.
