Target Audience

The Wonrabai Pico 2 W is a microcontroller development board built around the RP2350 chip. It suits makers and engineers who need integrated 2.4 GHz 802.11n Wi-Fi and Bluetooth 5.2 for wireless IoT prototypes. The board ships with a yellow pre-soldered header and a USB cable, so it is ready for immediate breadboard experimentation.

Memory and Performance

The RP2350 provides a dual-core Arm Cortex-M33 and dual-core Hazard3 RISC-V architecture clocked up to 150 MHz. On-board resources include 520 KB of SRAM and 4 MB of Flash memory. The 26 multi-function GPIO pins support 2 SPI, 2 I2C, 2 UART, 3 ADC channels and 16 PWM outputs, while 12 programmable I/O state machines handle custom peripheral timing.

Upgrade Context

This board replaces the earlier Pico 2 by adding the Infineon CYW43439 wireless chip and onboard antenna. The jump is worthwhile when a project requires cable-free connectivity or Bluetooth 5.2 peripherals. It is not a fit for applications that need high-speed wired networking, large external memory pools or PCI Express expansion.

Questions about this item

Will the 26 GPIO pins on this Pico 2 W board align with my existing Raspberry Pi Pico HATs?

Yes, the 26 multi-function GPIO pins keep the standard Pico pinout so your current HATs and expansion boards will connect without adapters.

How can I confirm the RP2350 dual-core processor and wireless module are functioning after I plug it in?

The board appears as a USB mass-storage device; drag a MicroPython UF2 file onto it, then run a script that prints the CPU frequency and scans for Wi-Fi networks to verify both cores and the CYW43439 radio.

Does the kit include the yellow pre-soldered header and a USB cable, or must I source them separately?

The yellow header is already soldered to the castellated pads and a USB cable is supplied in the box, so no extra parts are required to start developing.
