Compact and powerful
The form factor fits perfectly into my small drone controller chassis. The increased SRAM is a game-changer for buffering image data from small cameras. Highly recommended for anyone moving beyond basic blinking LED projects.

Excellent value, minor documentation lag
Hardware is fantastic and very affordable. Since the RP2350 is relatively new, some third-party libraries are still catching up with full support, but the official SDK works flawlessly. Great board for learning advanced embedded concepts.

Great for industrial prototyping
I've been using this board for a custom motor control project. The dual-core architecture allows me to dedicate one core to real-time control loops while the other handles Wi-Fi communication via an external module. The build quality from Waveshare is excellent as always.

Seamless MicroPython experience
Flashed MicroPython in seconds. The REPL is responsive, and the additional processing power makes running lightweight ML models feasible. The USB-C port feels durable and connects securely.

Solid board for the price
Does exactly what it says on the tin. Pinout is compatible with most Pico accessories, which saved me time. Only giving 4 stars because I wish it came with pre-soldered headers, but that's a minor inconvenience.

Perfect upgrade from the original Pico
The RP2350 chip offers a noticeable performance boost over the previous generation. The Type-C connector is a welcome addition, making cable management much easier in my lab setup. Compilation times are faster, and it handles complex sensor data logging without breaking a sweat.
Q: What debugger interface does this board support?
A: The board exposes the SWD (Serial Wire Debug) pins on the bottom header, allowing you to connect external debuggers like the Raspberry Pi Debug Probe or J-Link for step-by-step debugging.
Q: Is this board compatible with existing Raspberry Pi Pico HATs?
A: Yes, the Waveshare RP2350-Zero maintains the same physical footprint and GPIO pinout as the standard Raspberry Pi Pico, so most existing HATs and shields will fit directly.
Q: Does the RP2350 support hardware floating-point operations?
A: Absolutely. The Arm Cortex-M33 cores include hardware floating-point units (FPU), which significantly accelerate mathematical calculations compared to software emulation.
Q: Is the 4MB flash sufficient for storing audio samples?
A: It depends on the sample rate and duration. For short sound effects or compressed audio, 4MB is adequate. For longer high-fidelity audio, you may need to attach an external SD card module via SPI.
Q: Can I power this board with a 3.7V LiPo battery?
A: Yes, you can connect a LiPo battery to the VSYS pin. The board features an onboard regulator that accepts input voltages between 1.8V and 5.5V, making it suitable for single-cell lithium batteries.
