Tindie Weblog | Twin-Core ARM M0+ on a Postage Stamp!


The Raspberry Pi RP2040 processor has been getting a variety of consideration just lately, and for good purpose. The twin ARM M0+ cores, plus DMA, programmable I/O, an enormous quantity of RAM and extra make it an ideal alternative for initiatives that want a variety of energy at a low value. However the draw back of all that energy is definitely implementing a PCB format for it — it requires exterior SPI flash, regulators, and cautious format and decoupling for optimum efficiency. Properly, this postage-stamp sized breakout board is a good way to make use of the RP2040 in your initiatives with out having to take care of all of the surface-mount soldering and PCB format work required!

The RP2040 Stamp breaks out all of the GPIO, in addition to the USB and SWD pins. As a result of the SPI flash is on-board, the QSPI pins don’t must be damaged out, which helps scale back the scale and nonetheless enable 2mm headers to be soldered to the castellated pads. It can be soldered straight as a surface-mount part, as seen with the optionally available RP2040 Stamp Provider Board.

The perfect a part of all — it’s licensed Open Supply {Hardware}! Which means all of the schematics, PCB format recordsdata and documentation is all freely obtainable so that you can modify and reuse beneath the CERN {hardware} license, MIT software program license, and Artistic Commons documentation license. Talking of documentation, it’s completely glorious. The creator, arturo182, has even created CAD footprints on your favorite EDA program, together with KiCAD 5/6, Eagle, and EasyEDA.

If you happen to’ve ever needed to begin utilizing the RP2040 in your individual initiatives however didn’t know the place to begin, this can be a nice strategy to convey the facility and adaptability of the chip into your {hardware} initiatives!
