RP2350 Stamp XL
by Solder Party
The Stamp was created to allow you to use the Raspberry Pi RP2350B in your designs without having to solder small-pitch QFN chips or worry about lots of external circuitry.
The RP2350 Stamp XL is partially pad-compatible with the smaller Stamps. The left-side pads as well as half of the top and bottom ones are exactly the same.
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.
We were also able to squeeze in two new functional pads: an LDO EN pad, connected to the LDOs EN signal, and a BAT STAT, connected to the LiPo charger’s STAT pin.
At only 1 by 1¾ inch, the Stamp XL packs a lot of features:
- 16MB of FLASH
- 500mA 3.3V LDO
- All 48 GPIOs broken out
- A footprint for a second QSPI FLASH/PSRAM
- Footprints for SWD and UART JST connectors, pin-compatible with the Raspberry Pi Debug Probe
- LiPo supply and charging circuit (with charging LED)
- USB broken out
- SWD broken out
- Reset Button
- Bootsel Button
- 12MHz crystal
and of course, everything that comes with the Raspberry Pi RP2350 itself:
- Dual core ARM Cortex-M33 or Hazard3 @ 150MHz
- 520kB SRAM
- 2 UARTs
- 2 SPIs
- 2 I2Cs
- 24 PWM channels
- 12 PIO state machines
- 1 HSTX peripheral
- USB with Host and Device support
The RP2350 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.
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.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
