Excellent value for money
I have worked with many development boards, and this offers unbeatable value. The RP2040 chip is fantastic for multitasking thanks to its dual cores. Build quality is solid, and it fits perfectly into tight enclosures.

Good board, watch the voltage
The board works great for 3.3V logic projects. Just remember that the GPIOs are not 5V tolerant, so you need level shifters if interfacing with older 5V sensors. Otherwise, performance is stellar for the price.

Great for learning MicroPython
As a beginner, I found this board very easy to set up with Thonny IDE. The documentation from Waveshare is helpful. Only giving 4 stars because the micro-USB port feels a bit fragile compared to USB-C boards.

Ideal for classroom workshops
We bought a batch of these for our robotics workshop. Students love how small they are, and they are robust enough to handle frequent plugging and unplugging. Programming via drag-and-drop is a huge plus for education.

Tiny powerhouse
Used this to control a small drone flight controller. The size-to-performance ratio is amazing. It boots up instantly, and the power consumption is low enough for battery-operated applications. Highly recommended!

Perfect compact board for IoT projects
This RP2040-Zero is incredibly small yet powerful. I used it for a weather station project, and the dual-core performance handles sensor readings and Wi-Fi transmission smoothly. The pinout is clearly labeled, making wiring a breeze.
Q: Is the flash memory user-upgradeable?
A: The 2MB QSPI flash is soldered onto the board and is not designed to be replaced or upgraded by the end-user. It is sufficient for most standard MicroPython and C++ applications.
Q: Are there example codes available for temperature sensors?
A: Yes, Waveshare provides a wiki with extensive examples, including code for DS18B20, DHT11, and BME280 temperature sensors in both MicroPython and C/C++. You can find these on the product support page.
Q: What debugger interface does this board support?
A: The board supports SWD (Serial Wire Debug) for debugging. You can use a Raspberry Pi Pico Probe or any standard SWD debugger like the J-Link or ST-Link to debug your code.
Q: Does this board support Bluetooth connectivity?
A: No, the RP2040 chip does not have built-in Bluetooth or Wi-Fi. However, you can easily add these capabilities by connecting external modules via UART, SPI, or I2C interfaces.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: Yes, you can connect a 3.7V LiPo battery to the VBUS pin, but please ensure the voltage does not exceed 5.5V. For safe charging and power management, we recommend using a dedicated battery management module.
