WaveShare RP2040-Zero Mini Development Board

SKU CH-2S10-0ZFG2

Pico-compatible RP2040 board with dual-core Arm Cortex-M0+ at 133 MHz, 2 MB flash, 29 GPIO pins and castellated edges for direct SMD mounting

  • CPU TypeOther
  • Dual-core Arm Cortex-M0+ at 133 MHz for responsive embedded control
  • 2 MB onboard Flash stores firmware without external memory
  • 29 multi-function GPIOs including 20 edge pins for flexible I/O
  • Castellated module design enables direct SMD soldering to carrier boards
  • Drag-and-drop USB 1.1 mass-storage programming simplifies development workflow

Compact RP2040 Development Board

The WaveShare RP2040-Zero is a castellated microcontroller board built around the Raspberry Pi RP2040 chip. It targets makers and engineers who need a small footprint for surface-mount integration or breadboard prototyping. The dual-core Arm Cortex M0+ processor runs up to 133 MHz with 264KB SRAM and 2MB flash memory.

Verify Carrier Board Compatibility

Check that your carrier board layout matches the castellated edge pins for direct soldering. Ensure your toolchain supports C/C++ or MicroPython development and that you have a USB Type-C cable for power and drag-and-drop programming. Confirm the 1.1 USB interface meets your host or device communication requirements.

Integrates Via Castellated Pins

The module solders directly onto a custom PCB, freeing up space compared to header-based boards. It exposes 29 multi-function GPIO pins, with 20 available on the edge pinout and the rest via solder points. Peripheral sets include 2 SPI, 2 I2C, 2 UART, 4 ADC channels and 16 PWM outputs for embedded control tasks.

Questions about this item

Does the RP2040-Zero ship with headers or cables, or must they be bought separately?

The board is a castellated module with no headers or cables included; you will need to source pin headers, a USB-C cable and any carrier board yourself.

Should I choose this Zero Mini over a full-size Pico board for my project?

Pick the Zero Mini when you need the smaller 29 × multi-function GPIO layout and direct SMD mounting via castellated edges; choose a full-size Pico if you prefer standard 0.1 in headers and more edge-accessible pins.

What does the 133 MHz dual-core Cortex-M0+ actually deliver in a real application?

It provides up to 133 MHz flexible clock speed with 264 KB SRAM and 2 MB flash, enabling deterministic real-time control across 2 SPI, 2 I2C, 2 UART, 4 ADC channels and 16 PWM outputs.
