Replacement: None. We are no longer carrying this module, but we still have a selection of Nordic transceivers. This page is for reference only.
Description: This is a breakout board for the Nordic nRF24AP1. This transceiver IC is capable of talking to various wireless products that utilize the ANT protocol such as heart rate straps, bicycle computers, tachometers, and more! The nRF24AP1 is a combination of the nRF2401A with a masked in protocol called 'ANT' and a simple to use serial interface.
The nRF24AP1 breakout board can be configured to operate at different baud rates by closing two solder jumpers. The board is shipped with settings for 4800bps.
This device cannot communicate with Polar Heart Rate products. This device uses a digital signal, where the Polar system uses a low-frequency EMF signal. The nRF24AP1 is compatible with modern Garmin and Sunnto products that use the ANT protocol.
