The RP2040-Zero is a tiny development board built on the same RP2040 chip as the Raspberry Pi Pico, so it runs the same MicroPython, C/C++ and Arduino code. It packs USB-C, BOOT and RESET buttons and a WS2812 RGB LED onto a 23.5 x 18.0mm board with castellated edges, for macropads, small USB gadgets and builds where a full-size Pico will not fit. Need 16MB of flash or standard Pico spacing? See our RP2040 16MB board.

What's in the box

1×
RP2040-Zero board with loose pin headers

Two side strips and a short bottom strip, not soldered, so you can fit headers or solder the board flat.

Great for

A USB macropad or game controller using the RP2040 as a keyboard or gamepad
Driving WS2812 LED strips from PIO
A small sensor logger inside a tight enclosure
Soldering flat onto your own carrier PCB
Learning MicroPython with Pico tutorials
A USB-to-I2C or USB-to-UART helper for another project

Wiring & getting started

  1. Fit the headers you need

    For a breadboard, solder the two side strips only. Leave the bottom 5-pin strip off, as its pins would share one breadboard row.

  2. Enter the bootloader

    Hold BOOT, plug in a USB-C data cable, then release BOOT. A drive called RPI-RP2 appears.

  3. Load firmware

    Drag the MicroPython .uf2 for the Raspberry Pi Pico onto the drive, then open Thonny and choose MicroPython (Raspberry Pi Pico).

  4. Check it works

    Blink the RGB LED with the neopixel module on GP16. For Arduino, install the Raspberry Pi Pico/RP2040 core by Earle Philhower and choose Waveshare RP2040 Zero.

Frequently Asked Questions

Answers to the questions buyers ask most.

Will my Raspberry Pi Pico code run on it?
Yes. It uses the same RP2040 chip and 2MB flash size as a Pico, so the standard Pico MicroPython firmware, CircuitPython, the Pico C/C++ SDK and Arduino all work. The pin positions differ from a full-size Pico, so wire by the GP numbers printed on the board.
How do I program it in the Arduino IDE?
Add the Raspberry Pi Pico/RP2040 core by Earle Philhower in Boards Manager, then choose Waveshare RP2040 Zero as the board. For the first upload, hold BOOT while you plug it in.
Can I use it on a breadboard?
Yes, with the two side header strips soldered on. Leave the bottom 5-pin strip off on a breadboard, because those pins would sit in one breadboard row and short together. The underside pads GP17 to GP25 are for soldering wires or a carrier board.
Can I connect 5V sensors or signals?
Not directly. The GPIO are 3.3V and not 5V tolerant, so use a logic level converter for 5V signals. You can power the board from USB-C or from 5V on the 5V pin, and run 3.3V modules from the 3V3 pin.
It is not showing up on my computer. What do I do?
Hold BOOT, plug the cable in, then release BOOT; the RPI-RP2 drive should appear. If nothing appears, try another cable, as many USB-C cables are charge-only with no data lines.
Does it have WiFi or Bluetooth?
No, the RP2040 has no wireless. For a board this size with WiFi and Bluetooth, see our ESP32-S3 Zero.
What is the difference from your RP2040 16MB board?
This one is much smaller (23.5 x 18.0mm, 3.4g) with 2MB of flash and castellated edges. The RP2040 16MB board is full Pico size with standard header spacing and 16MB of flash.
Is it an official Raspberry Pi board?
No. It is a third-party board built around the RP2040 chip designed by Raspberry Pi.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
