Dragino UART
From Wiki for Dragino Project
The Dragino has a UART (SOUT,SIN) interface available at the 2x8 connector which can be used to communicate with MCUs which support UART.
Connect to Arduino Duemilanove
Before the connection, make sure the Arduino doesn't power by the USB port or power plug. use the Dragino 3.3v to power the Arduino (connect to 5v rail of Arduino). this will remove the risk of destroy the Dragino by the 5V power from Arduino (if power by USB).
Connection:
| Dragino MS12 | Duemilanove |
|---|---|
| 3.3V | 5V |
| GND | GND |
| SOUT | RX |
| SIN | TX |
