NOTE: The CYW43439 supports both 802.11 wireless and Bluetooth, initially Pico W does not have Bluetooth support. Support may be added later, and will use the same SPI interface. If support is added existing hardware may require a firmware update to support Bluetooth, but there will be no hardware modifications needed.

Technical Specification
  • RP2040 microcontroller with 2MB of flash memory
