Arduino UNOと3GIMとの接続

ピン配列

以下のような組み合わせで3GIMとArduinoを接続します。

3GIMのPIN番号(上面から見て右側から) 説明 Arduino 補足
1 3GIM ON/OFF D6 ライブラリのデフォルトはD6。任意番号で指定可能
2 RX (for Arduino TX) D5 ライブラリのデフォルトはD5。任意番号に変更可能(IEM_RXD_PIN)
3 TX (for Arduino RX) D4 ライブラリのデフォルトはD4。任意番号に変更可能(IEM_TXD_PIN)
4 5v 5vピンに刺す。 IOREF PWR_ON,RX,TXのロジック電圧。(3GIMにIO電圧を供給用)
5 3.3v 3.3v 5vピンに刺してはいけない!
6 GND GNDピン GNDであればどこでも
