RN-41-SM / RN-42-SM
  • Class 1/Class 2 Bluetooth 2.1+EDR Socket Module
  • Part#: RN-41-SM/RN-42-SM



The RN-41-SM/RN-42-SM is a through hole, low power socket module with TTL UART and RS-232 interface. This board is an ideal prototyping platform to interface the RN-41/RN-42 to a micro controller.

Supporting multiple Bluetooth profiles such as SPP and HID and simple UART hardware interface, the RN-41-SM / RN-42-SM is simple to integrate into an embedded system or simply connect to an existing device. The RN-41/RN-42 is FCC and Bluetooth SIG certified making it a complete embedded Bluetooth solution.

The RN-41/RN-42 modules support multiple Bluetooth profiles (SPP, DUN and HCI) makig it the perfect solution for adding Bluetooth wireless capability to existing products without redesign, saving you significant time and money.
