Raspberry PI RP2350 Compact Boards also comes with a Carrier board

Sweden-based consumer electronics company Solder Party has just released two new RP2350 Compact Boards named the RP2350 Stamp, and RP2350 Stamp XL. The company has also released a carrier board that can be configured with either the RP2350 Stamp or the RP2350 Stamp XL. As the RP2350 Stamp has a more compact form factor the GPIO options are limited whereas the Stamp XL utilizes all the GPIOs found on the RP2350B MCU.

Previously we have written about many stamp-sized boards like the Waveshare RP2040-Tiny, the RPDot RP2040 the Pimoroni Tiny2040 and much more feel free to check those out if you are looking for some tiny and powerful development boards.

  • Both include:
    • 12x PIO state machines
    • HSTX peripheral
    • USB host and device
    • SWD for debugging
    • 5V, 3.3V, VBAT, and GND
• RP2350 Stamp XL Specific:

• Misc:
  • Reset and Boot Buttons (Both)
  • 12MHz crystal (Both)
• Power Supply:
  • Supply Voltage: 3.6 to 6.5V DC via “5V” pin (Both)
  • 500mA 3.3V LDO (Both)
  • LiPo supply and charging circuit (with charging LED) (Both)
• Dimensions:
  • RP2350 Stamp: 25.4 x 25.4 mm
  • RP2350 Stamp XL: 44.5 x 25.4 mm

The RP2350 Stamp XL is a nice big module that looks very interesting to work with the new RP2350B MCU and the Arduino Mega-sized career board makes things a lot easier by making existing shields work with Arduino UNO and more.

RP2xxx Stamp Carrier XL Specifications

• Compatibility:
  • Supports all RP2-based Stamp boards (RP2040 Stamp, RP2350 Stamp, RP2350 Stamp XL)
  • Mega/Due form factor for compatibility with many shields, including Uno shields
• Stamp Mounting Options:
  • Combo 3-in-1 SMD/TH/FlexyPin Stamp footprint
  • Solder Stamp directly
  • Use 2mm pin headers + sockets for plug-in/out
  • Use FlexyPins for pop-in/out without soldering
  • Functions as Stamp flashing and testing jig
• Power Options:
  • LiPo battery
  • USB
  • DC jack (7-12V, center-positive)
  • LiPo charging when connected to DC or USB
• Connectivity & Features:
  • USB Host and Device connectors with toggle switch
  • microSD socket
  • Micro HDMI-shaped connector (connected to HSTX peripheral)
  • SWD JST connector (compatible with Raspberry Pi Pico Probe)
  • UART JST connector (compatible with Raspberry Pi Pico Probe)
  • Qwiic connector
  • 3.7/4.2V LiPo connector
  • Two user buttons
  • PMOD header
  • USR LED
  • Power (3.3V) LED
  • DC Jack
• Shield Compatibility:
  • Follows Mega/Due/Uno shield pinout
  • Works with 3.3V IOs (pins are NOT 5V-tolerant)
• Dimensions: 101.6 x 53.34 mm

The RP2xxx Stamp Carrier XL’s unique 3-in-1 footprint allows you to directly solder, plug-in with headers, or use FlexyPins for easy swapping during development. It even works as a flashing jig! The included CircuitPython firmware makes it easy to get started.

The RP2350 RP2350 Compact Boards Stamp modules and Carrier are not available for purchase at the time of writing but, they’ll be out soon in the Lectronz store, priced at $11 and $7.50 respectively.
