A reference design for the RP2040 Stamp, also a full-fledged RP2040 Uno form-factor development board!
The Carrier is a reference design for the RP2040 Stamp. 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.
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.
