RN42N - Class 2 Bluetooth Module

Download the RN42N datasheet PDF. This datasheet also covers the RN42 variant, as both devices belong to the same class 2 bluetooth module family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Fully qualified Bluetooth® version 2.1 module, supports version 2.1 + Enhanced Data Rate (EDR).
  • ASCII command interface over UART.
  • Postage-stamp-sized form factor: - RN42: 13.4 x 25.8 x 2.4 mm - RN42N: 13.4 x 20.5 x 2.4 mm.
  • Low-power (26 A sleep, 3 mA connected, 30 mA transmit).
  • UART (SPP or HCI) and USB (HCI only) data connection interfaces.
  • Sustained SPP data rates: 240 Kbps (Slave mode), 300 Kbps (Master mode).
  • HCI data rates:.
