## Description

# Summary

The RP2350 Stamp is a hand-solderable SMD/TH module that integrates the Raspberry Pi RP2350A MCU with 16MB of FLASH, an LDO, LiPo charge management (including a charge LED), a reset button, and a bootsel button. It breaks out all the GPIOs as well as USB, SWD, BOOTSEL, RST, and the voltage pins.

# Details

The Stamp was created to allow you to use the Raspberry Pi RP2350A 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 including KiCad, Eagle CAD, and EasyEDA** [on our Github](https://github.com/solderparty/rp2xxx_stamp_footprints/).

### Dimensions

![Dimensions](https://images.lectronz.com/lektronz-images/3aom7ntwkgyaageowwot5bvarg2f)

At only **1 by 1 inch**, the Stamp packs a lot of features:
* **16MB of FLASH**
* **500mA 3.3V LDO**
* **All 30 GPIOs broken out**
* 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.

### Pinout

**Note: The leaflet sent with the Stamps has the description for 3.3V and 5V swapped, the pin positions are correct, only the descriptions are swapped. The above image is fixed and doesn’t contain that error.**
