Description: The USB ANT Stick enables an easy connection to the Nordic nRF24AP1. By using the popular FTDI COM Port Drivers, all one needs to do is plug the device into a USB hub on the computer and they instanly can send and receive data to and from the nRF24AP1 module. This unit is great for developing hardware using the ANT protocol and through an easy USB connection.

The nRF24AP1 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 or any other device that use the ANT protocol.
