Waveshare RP2350B-Plus-W is a development board that follows the Raspberry Pi Pico 2 W form factor, but offers 41 GPIOs thanks to the RP2350B MCU, integrates 16 MB of flash, and includes a USB-C port.So, in several ways, it’s an upgrade over the RP2350A-based official board, which offers only 26 GPIOs via two 13-pin GPIO headers, 4MB of flash, and a micro USB port. Since it’s the same size, where do the extra GPIOs come from? Answer: The company simply added 15 pads to the bottom of the board, not quite as convenient since it’s requires soldering, but it does the job.Waveshare RP2350B-Plus-W specifications:
