Solder Social gathering’s RP2040 Stamp, an ultra-compact module constructed round Raspberry Pi’s RP2040 microcontroller, is now up on the market — alongside a useful service board for experimentation and prototyping.
Pseudonymous maker “arturo182” unveiled the RP2040 Stamp earlier this 12 months, promising a board that might get away all of the performance of Raspberry Pi’s first in-house microcontroller chip, the RP2040, in a footprint the dimensions of a postage stamp. Designed, as with Raspberry Pi’s personal RP2040-powered gumstick-style Pico board, with castellated pins, the Stamp can be utilized with pin headers — however is equally well-suited to be used as a surface-mount module.

In addition to the RP2040 microcontroller, which incorporates two Arm Cortex-M0+ cores, 264kB of static RAM (SRAM), and an eight-slot programmable enter/output (PIO) system, the RP2040 Stamp affords 8MB of exterior flash, a bodily reset button, an LDO voltage regulator, lithium-polymer battery cost administration with cost LED, and an RGB NeoPixel LED for good measure.
“The Stamp was created to mean you can use the Raspberry Pi RP2040 in your designs with out having to solder small-pitch QFN chips or fear about a lot of exterior circuitry,” Solder Social gathering explains of the board. “All it’s essential get you began is a 5V provide or a LiPo battery. The Stamp will care for the charging and switching the facility sources.”

These not fairly able to design their very own service board, in the meantime, can decide up the RP2040 Stamp Service. Designed to simply accept an RP2040 Stamp at its coronary heart, both soldered straight or utilizing feminine and male pin headers to make it simply detachable, the service board mimics the favored Arduino Uno footprint and pinout and affords USB Kind-C for information and energy, LiPo and DC jack for energy, a Qwiic connector, and a BOOTSEL button for switching boot modes.
Solder Social gathering has been beta-testing the boards with makers all over the world for a while, and is now able to promote them — although, on the time of writing, each have been displaying as out-of-stock.
events can signal as much as be notified when extra stick is offered on the RP2040 Stamp and RP2040 Stamp Service Tindie product pages — the place the previous is being offered for $12 and the latter for $6.50.
