Perfect compact board for IoT projects
This RP2040-zero is exactly what I needed for my space-constrained drone project. The pin headers are pre-soldered which saved me time, and the performance is identical to the standard Pico but in a much smaller footprint.

Seamless replacement for Pico in tight spaces
If you need the power of the Pico but don't have the space, this is the answer. The pinout is logical, and the voltage regulation is stable. I successfully ported my existing Pico code without any modifications.

Good board, minor heating under load
The board works great for most tasks. I noticed it gets slightly warm when driving multiple servos and running WiFi via an external module simultaneously, but nothing concerning. Just ensure adequate ventilation in your enclosure.

Reliable and robust
We bought ten of these for our university lab. They have held up well under constant use by students. The build quality is solid, and the castellated holes allow for custom PCB integration if needed later.

Excellent value for dual-core processing
I've used several RP2040 boards, and this Zero version offers the best price-to-size ratio. The dual-core architecture handles multitasking smoothly for my sensor data logging application. Highly recommended for industrial prototyping.

Great for learning MicroPython
As a beginner, I found this board very easy to set up. The documentation from Waveshare is decent, though I mostly relied on the official Raspberry Pi docs. Only giving 4 stars because the USB cable included was a bit short.
Q: Is this compatible with the Arduino IDE?
A: Absolutely. You can program the RP2040-zero using the Arduino IDE by installing the Raspberry Pi Pico board package via the Board Manager.
Q: Does it support external QSPI flash expansion?
A: While the board has 2MB of onboard flash, the RP2040 chip supports external QSPI flash. However, accessing external flash requires custom wiring and software configuration as there are no dedicated footprints on this compact board.
Q: Does this board come with pin headers already soldered?
A: Yes, this specific model comes with male pin headers pre-soldered, ready for immediate use with breadboards or jumper wires.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: You can connect a LiPo battery to the VSYS pin, but please note that the input voltage range is 1.8V to 5.5V. Ensure your battery setup includes appropriate protection circuitry.
Q: What is the maximum current draw per GPIO pin?
A: Each GPIO pin can safely source or sink up to 4mA. The total current drawn from all GPIO pins combined should not exceed 50mA to ensure stability.
