RF51422 : ANT+ Uart RF Transceiver Module Adopts SOC Chip
- The RF51422 module is an ANT+ RF transceiver module with a UART interface. It uses a high-performance SOC chip inside and integrates the ANT+ protocol stack. Customers can directly realize the data sending and receiving communication between ANT+ devices through standard UART commands, which are mainly used in the development of standard ANT+ protocol related products. This module is compatible with most of the ANT+ protocol devices on the market.
- RF51422 is manufactured and tested strictly using lead-free process and complies with RoHS and Reach standards.

| 1 | VCC | Power positive |
| 2 | GND | Power ground |
| 3 | TXD | Serial TXD |
| 4 | RXD | Serial RXD |
| 5 | SET | Enter the DFU (firmware upgrade) mode control pin, pull this pin low, and then give a low pulse to the RESET pin, and the module will enter DFU mode after restarting. Pull up or leave this pin unconnected, power-on or reset will enter the normal operating mode. |
| 6 | CS | Sleep control pin, pull down the CS module to sleep, pull it high or float to make the module work normally |
| 7 | RESET | Pull this pin low to reset the module, pull it high or floating, the module will work normally |
| 8 | GND | Power ground |
| 9 | ANT | Antenna interface |
