Summary

The Carrier is a reference design for the RP2040 Stamp (you can find the Stamp standalone here). It comes with a combo SMD/TH Stamp footprint, you can solder the Stamp directly to the Carrier or use 2mm pin headers + sockets to be able to plug it in and out.

The Carrier extends the functionality of the Stamp by adding a BOOTSEL button, LiPo and Qwiic connectors, USR and PWR LEDs, an SWD header, and a USB Type-C connector.

The board can be powered from the LiPo, over USB, or with a DC jack.

Details

By using the RP2040 Stamp Carrier, you get everything that comes with the Stamp itself:

• 8MB of FLASH
• 500mA 3.3V LDO
• A Neopixel
• LiPo supply and charging circuit (with charging LED)
• A reset button
• 12MHz crystal

On top of that you get:

• A bootsel button
• 3.7/4.2V LiPo connector
• Qwiic connector
• USR LED
• Power (3.3V) LED
• SWD header
• USB Type-C connector
• DC Jack

The DC Jack input is center-positive and supports voltages in the range of 7-12V. If you have the LiPo and either DC or USB connected, the battery will begin charging.

The board follows the Uno shield pinout, making it compatible with a large ecosystem of shields, as long as they work on 3.3V IOs. The pins are not 5V-tolerant.

The SWD header follows the Cortex 10-pin standard.

The CircuitPython firmware for the RP2040 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.

What you get

• A Uno form-factor RP2040 Stamp Carrier board
• A set of headers: 1x 6 pin header, 2x 8 pin headers, 1x 10 pin header (all not soldered)
• A pinout and functionality reference sheet
• (Optionally) An RP2040 Stamp (not soldered to the Carrier)
