RF51422 is a compact wireless transceiver module with built-in ANT+ protocol interface for various applications

The ANT+ protocol is a low-power wireless transmission technology primarily used for data transfer between fitness devices, sports sensors, and smart devices. It operates on the 2.4GHz offers characteristics of low power consumption, low latency, and high reliability. The ANT+ protocol wide applications in the fitness industry, such as heart rate monitoring, step counting, and motion tracking. Therefore, for compact sports devices, ANT+ modules not only need to consider power consumption but also focus on miniaturized module design. A small-sized module design facilitates integration and helps reduce the overall volume and weight of the devices. Additionally, there is a demand for customized module solutions in specific application scenarios.

The RF51422 module is a UART interface ANT+ wireless transceiver module, equipped with a high-performance System-on-Chip (SOC) chip and integrated ANT+ protocol stack. Customers can establish communication between ANT+ devices directly through standard UART commands, making it suitable for developing products compliant with the standard ANT+ protocol. This module is compatible with the majority of ANT+ protocol devices available in the market. The RF51422 module is produced and tested using lead-free technology, adhering to RoHS and Reach standards.

The RF51422 module features the following built-in ANT+ profiles:

1. ANT+ Heart Rate Monitor Profile: Used for connecting and transmitting heart rate monitor data.
2. ANT+ Bike Speed and Cadence Profile: Used for connecting and transmitting bike speed and cadence data.
3. ANT+ Power Meter Profile: Used for connecting and transmitting power meter data.
4. ANT+ Fitness Equipment Profile: Used for connecting and transmitting fitness equipment data (e.g., treadmill, exercise bike, etc.).
5. ANT+ Weight Scale Profile: Used for connecting and transmitting weight scale data.
6. ANT+ Foot Pod Profile: Used for connecting and transmitting foot pod (walking sensor) data.
7. ANT+ Lighting Control Profile: Used for connecting and controlling lighting devices.
8. ANT+ MultiSport Speed and Distance Profile: Used for connecting and transmitting speed and distance data for various sports activities.

These built-in ANT+ profiles enable the RF51422 module to support a wide range of applications and provide seamless connectivity and data transmission for various ANT+ compatible devices.

The performance parameters of RF51422 are as follows:

After powering on the module, it will automatically open the scan channel of the ANT+ device and output a startup message through the serial port. At this time, if there are ANT+ devices transmitting data, the serial port will continuously output the received data. If you do not need this scan channel, you can close it using specific commands. The module has three working modes: normal mode, sleep mode, and firmware upgrade mode. Another feature of this module is its small size design.
