But at least, it’s pin-to-pin compatible with the original Raspberry Pi Pico so existing add-ons or carrier boards should work without modifications. Power Supply – 5V via Micro USB port or 1.8 to 5.5V DC via VSYS pinĪpart from the addition of the WiFi module and antenna, that is basically the same design and they did not even add a reset button that would make programming quite easier… The user LED is now connected to the CYW43439 wireless chip but still controllable from the RP2040 SDK.

Misc – BOOTSEL button, user LED ( GP25.Debugging – 3-pin Arm Serial Wire Debug (SWD) port.2x 20-pin 2.54mm pitch header and castellated holes with 26x GPIOs, 3x 12-bit ADC up to 500 Kbps, 2x UART, 2x I2C, 2x SPI, 16x PWM, 2 × programmable I/O (PIO) blocks with 8 state machines.USB – 1x Micro USB 1.1 port used for power and programming.Connectivity – 802.11b/g/n WiFi 4 with ABRACON onboard antenna (Infineon CYW43439 connected over SPI).MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller 133 MHz with 264KB SRAM.Bluetooth is not enabled right now, but may be at a later stage. Having said that, I was actually expecting a competitor to ESP8266 or ESP32 with a new Raspberry Pi wireless microcontroller, but it did quite happen that way as the Raspberry Pi Pico W features the same Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller found in Raspberry Pi Pico board coupled with an Infineon CYW43439 chip that’s supposed to support both 2.4 GHz WiFi 4 and Bluetooth LE 5.2. I was expecting the next official Raspberry Pi board to be either an update of Raspberry Pico with WiFi and Bluetooth or with a machine learning accelerator and the new $6 Raspberry Pi Pico W delivers that wish through the addition of 2.4GHz WiFi 4.
