Waveshare quality as always
The build quality is top-notch. The soldering is clean, and the USB port feels sturdy. Highly recommend for anyone looking to upgrade from the RP2040 ecosystem.

Ideal for Learning
As a student learning embedded systems, this board is fantastic. The integration with Thonny IDE was instant, and I was blinking LEDs within minutes of unboxing.

Perfect for MicroPython Projects
The RP2350-One board is incredibly easy to set up. The Type-A port makes connecting peripherals like keyboards or flash drives straightforward without needing extra adapters. MicroPython runs smoothly on the 4MB flash.

Great value, minor documentation gaps
Hardware quality is excellent and the pinout is standard. I had to dig a bit into the community forums to find specific examples for the new RP2350 features, but once configured, it works flawlessly.

Compact and Powerful
I love the compact form factor. It fits perfectly into my custom enclosures. The dual-core performance is a significant upgrade for my sensor logging projects compared to older boards.

Solid choice for prototyping
Used this for a quick robot controller prototype. The GPIO response time is impressive. Only wish it had a built-in battery charging circuit, but that's expected for this price point.
Q: What is the maximum current draw per GPIO pin?
A: Each GPIO pin can safely source or sink up to 4mA, with a total limit for all GPIOs combined. Please refer to the RP2350 datasheet for detailed electrical characteristics to avoid damaging the board.
Q: Is the 4MB flash memory expandable?
A: No, the 4MB flash is soldered directly onto the board and cannot be expanded. However, you can connect external SD card modules or SPI flash chips via the GPIO pins if more storage is needed.
Q: Does this come with a pre-installed bootloader?
A: Yes, the board comes with the standard Raspberry Pi UF2 bootloader pre-installed, allowing you to program it by simply dragging and dropping files when in boot mode.
Q: Does this board support CircuitPython in addition to MicroPython?
A: Yes, the RP2350-One is compatible with CircuitPython, though you may need to compile or download the specific nightly build for the RP2350 chip depending on the current release status.
Q: Can I power this board using a standard phone charger?
A: Absolutely. Since it features a USB Type-A port, you can power it using any standard 5V USB power source, including phone chargers, power banks, or computer USB ports.
