Twin RP2040 microcontroller boards with dual-core Arm Cortex-M0+ running up to 133 MHz, USB-C connectivity and castellated pins for surface-mount integration

  • Dual-core Arm Cortex-M0+ up to 133 MHz for responsive real-time tasks
  • RP2040 microcontroller chip provides Raspberry Pi silicon in a compact module
  • USB-C connector simplifies power and data with a single reversible cable
  • Castellated edges enable direct surface-mount integration into custom PCBs
  • Two boards per pack gives a spare or parallel development platform

Two-board RP2040 development kit

This pack contains two RP2040-Zero mini boards built around the Raspberry Pi RP2040 microcontroller chip. Each board delivers a dual-core Arm Cortex-M0+ processor with a flexible clock up to 133 MHz. The Pico-like form factor targets hobbyists, students and engineers who need a low-cost platform for embedded experiments, IoT edge nodes or rapid prototyping. Comprehensive SDK, documentation and tutorials help users start quickly with C/C++ or MicroPython.

Low-power thermal profile

The RP2040 microcontroller draws very little current in typical workloads, so the boards run cool without heatsinks or active cooling. No fan noise is present because none is required. Power is supplied through the onboard USB-C connector, keeping the wiring simple for bench testing or battery-powered deployments. The efficient dual-core architecture maintains responsive performance while staying within a modest power envelope.

Castellated edges for SMD integration

Each module features castellated pads along its perimeter, allowing the board to be surface-mounted directly onto a custom carrier PCB. This layout suits volume production or compact designs where a header socket would add unwanted height. The USB-C port remains accessible for programming and serial communication after mounting. Configurable pin functions give developers flexibility to assign GPIO, SPI, I2C, UART, PWM or ADC roles as the application demands.

Questions about this item

How do I solder the castellated edges of the RP2040-Zero to my custom PCB?

Align the castellated pads with your board footprint, apply flux, then reflow solder each edge pad using a fine tip or hot air; the module sits flush for surface-mount assembly.

What long-term upkeep does the RP2040 microcontroller require?

The RP2040 chip itself needs no scheduled maintenance; keep the board free of dust and moisture, and verify solder joints if the assembly sees vibration.

At what clock speed does the dual-core Arm Cortex-M0+ processor top out?

The flexible clock runs up to 133 MHz, which is the maximum frequency the RP2040 cores can sustain.
