[Size]:21*36mm
[Introduction]:E34-2G4D27D is based on nRF24l01+, working at 2.4~2.518GHz, TTL output.It’s compatible with 3.3V and 5V IO port voltage, using serial port for data transmission and reception, reducing the threshold of wireless applications.
Pin No. | Pin Item | Pin Direction | Function |
---|---|---|---|
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 indicate module’s working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configuredas open-drain output or push-pull output (floating is allowed). |
6 | VCC | - | Power supply 2.3V-5.2V DC |
7 | GND | Input | Ground |
8 | Fixing hole | Input | Fixing hole |
9 | Fixing hole | - | Fixing hole |
10 | Fixing hole | - | Fixing hole |
