Serial USB-A to Wireless nRF Module (SNM-A)

SNM-A module is a smart serial USB (A-type connector) to wireless module based on the nRF24L01+ from Nordic Semiconductor and uses the controller ATMEGA8.

The nRF24L01+ module is designed to operate in the global 2.4GHz ISM frequency band and uses GFSK modulation to transmit data.

ATMEGA8  microcontroller comes pre-programmed to support RMxN relay modules protocol. However, the user can program ATMEGA8 microcontroller with other firmware.

SNM-A module uses a CH340 chip as a USB to Serial converter.

  Features: 

• Compatible with the protocol of RMxN wireless relay module.

• USB interface: USB type A connector.
• Driver: CH340.
• Baud rate: 115200.
