There are plenty of RP2040 proto boards on the market — heck, there are even plenty of small RP2040 boards on the market! However we predict this can be the smallest, fully-featured board that features all I/O damaged out, in addition to energy, reset, and choices for making it even smaller baked proper in!
A part of the key of maintaining I/O is by utilizing 1mm pitch pin header footprints. These headers can be found at your favorite components distributor, and are generally utilized in business to save lots of house. They’re a bit difficult at hand solder, however with some apply and good high quality flux, it shouldn’t be too tough.
The opposite secret of this board is the flexibility to take away the USB-C connector to save lots of on peak if wanted! The VBUS, D+, D- and GND pins are damaged out to the aspect of the connector if you wish to wire them up straight. And the SOIC EEPROM is hiding a footprint for a UDFN-8 EEPROM beneath it! So you’ll be able to minimize down the peak even additional if you actually need to get it into a good spot. All of the design recordsdata are open, so in case you’re actually caught for house, you possibly can even try to get the boards manufactured thinner, however wanting on the footage I feel they’re already as skinny as you’ll be able to simply purchase!
If you have to squeeze some severe processing energy into an extremely small house, the proto2040 is for you. Test it out, and welcome vendor Treble to Tindie!
