Raspberry Pi SC1169 Radio Module 2 (RM2)

Raspberry Pi SC1169 Radio Module 2 (RM2) is a compact, self-contained Wi-Fi® and BLUETOOTH® radio module developed to add wireless connectivity to Raspberry Pi’s high-performance, low-cost microcontrollers. The RM2 is a cost-efficient solution with minimal external components (requiring only SPI, power, and reset signals). The device delivers GPIO expansion options for added flexibility.

The Raspberry Pi SC1169 Radio Module 2 implements the Infineon CYW43439 single-chip combo device featuring 1×1 single-band 2.4GHz Wi-Fi 4 (802.11n) and Bluetooth 5.2 for low-cost applications.

Features

  • Wi-Fi 4 (802.11n), single-band (2.4GHz)
  • Bluetooth 5.2
  • Bluetooth Classic and Bluetooth Low Energy (LE)
  • Full software compatibility with Pico W and Pico 2W SDK
  • Three host-controlled GPIOs for added I/O capabilities
  • Low-pin-count gSPI host interface allows for simplified integration with minimal I/O requirements
  • SISO1 configuration supports efficient single-antenna wireless performance
  • Wi-Fi and Bluetooth can coexist with a shared antenna
  • Integrated internal PA and LNA for signal range and reliability
  • Supports 20MHz channels with data rates up to 96Mbps (PHY rate)
  • Bluetooth range supports up to 100m (Class 1) and 10m (Class 2)
  • -30°C to +70°C operating temperature
  • Low power consumption:
    • IEEE Power Save PM1 DTIM1 average rate 1:1.19mA
    • 43mA receive active rate MCS7 (at -50dBm)
    • 271mA transmit active rate MCS7 (at 16dBm)
  • 16.5mm x 14.5mm 21-pad castellated package
