[Introduction]:E34-2G4D20D est un module émetteur-récepteur sans fil de 20dBm. Il fonctionne sur 2400-2505MHz, il est facile à utiliser. La caractéristique typique du E34-2G4D20D est sa grande vitesse. Sous une variété de taux de bauds, E39-TTL-100 peut atteindre le duplex intégral, sans limitation de la longueur du paquet, supportant la transmission continue.
| 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). |
| 6 | VCC | Input | Power supply 2.3V-5.2V DC |
| 7 | GND | Input | Ground |
