[Introduction]：E34-2G4H20D est un module émetteur-récepteur sans fil 2.4G à haute vitesse et longue distance (peut être à la fois émetteur et récepteur). Le module est doté de l'algorithme FEC (Forward Error Correction), qui permet de corriger automatiquement les paquets de données interférents, ce qui améliore la capacité d'anti-interférence.

| Pin No. | Pin Item | Pin Direction | Pin Application |
|---|---|---|---|
| 1 | M0 | Input（weak pull-up） | Work with M1 & decide the four operating modes. Floating is not allowed, can be ground. |
| 2 | M1 | Input（weak pull-up） | Work with M0 & decide the four operating modes. Floating is not allowed, can be ground. |
| 3 | RXD | Input | TTL UART inputs, connects to external TXD (MCU, PC) output pin.Can be configured as open-drain or pull-up input |
| 4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin.Can be configured as open-drain or push-pull output |
| 5 | AUX | Output | To wake up the external MCU, during the procedure of self-check initialization, the pinoutputs low level. Can be configured as open-drain output or push-pull output (floating is allowed). |
