RP2040 Stamp

The Stamp was created to allow you to use the Raspberry Pi RP2040 in your designs without having to solder small-pitch QFN chips or worry about lots of external circuitry.

All you need to get you started is a 5V supply or a LiPo battery. The Stamp will take care of the charging and switching the power sources.

The castellated edges with 2mm pitch can be hand-soldered directly to a Carrier board, used with pin headers for more flexibility, or connected without soldering using FlexyPins, which are spring connectors designed for modules with castellated edges. You can find footprints for many PCB programs here.

At only 1 by 1 inch, the Stamp packs a lot of features:

  • 8MB of FLASH
  • 500mA 3.3V LDO
  • All 30 GPIOs broken out
  • A Neopixel
  • LiPo supply and charging circuit (with charging LED)
  • USB broken out
  • SWD broken out
  • Reset Button
  • 12MHz crystal

and of course, everything that comes with the Raspberry Pi RP2040 itself:

  • Dual core ARM Cortex-M0+ @ 133MHz
  • 264kB SRAM
  • 2 UARTs
  • 2 SPIs
  • 2 I2Cs
  • 16 PWM channels
  • USB with Host and Device support

The RP2040 comes with a pre-programmed ROM UF2 Bootloader, by pulling the BOOTSEL pin low and resetting, or by double-pressing the RESET button (if the FW supports it), you can upload new firmware using the USB disk drive.

In addition to the Stamps we also offer a few reference designs, see the Carriers in the Stamp-related category as well as our Flux projects.

The CircuitPython firmware for the Stamp comes with a built-in board files for the Carriers, for example you can access the RP2040 Stamp Carrier pins and interfaces by using import stamp_carrier_board as board. See here for all the available Carrier board files.
