NRF24 Min
Wireless NRF24 Transceiver
- Overview
- Commands
- Samples
- On-Module Code
A 2.4 GHz wireless transceiver based on the nRF24 family, with an SMA antenna connector and 125 selectable channels. Send and receive data between modules — peer to peer, no Wi-Fi or BLE involved — with simple text commands over any supported interface.
Common uses: low-power telemetry between robots, short-range remote control, classroom RF labs, sensor networks where Wi-Fi would be overkill, and any project that needs lightweight wireless without an IP stack.

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
| Function | Description |
|---|---|
SetMode(m, b1, a, p,b) | m: 0 = TX, 1 = RX, b1: address array, a: auto-ack (0/1), p: RX pipe number (0–5), b: baudrate (0=250k, 1=1M, 2=2M) |
RxReady() | return 1 if data is ready to read, 0: Rx empty |
ReadPl(b1) | Read payload data to array b1, return total bytes read |
Transmit(b1,l,t) | Transmit b1 array, l: length to transmit, t: timeout in milliseconds. Return 0: failed, 1: Success |
EnableRx() | Enable RX mode. |
EnableTx() | Enable Tx mode. |
DVer() | This driver version. |
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

- Script
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
