The 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 or by using pin headers. 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 Stamp, we also offer a reference design - the RP2040 Stamp Carrier.

The CircuitPython firmware for the Stamp comes with a built-in board file for the Carrier, you can access it using import stamp_carrier_board as board. After that, you can access all the Carrier pins and interfaces like you would with any other CPY board.
