Loading 3D model… large boards can take a moment.
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:
and of course, everything that comes with the Raspberry Pi RP2350 itself:
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.
In addition to the Stamps we also offer a few reference designs, see the Carriers in the as well as our .
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.
