New Product – ExtraCore MD – Alarmingly tiny Arduino Clone!

Modern Device >>

Dustin Andrews created the first ExtraCore Arduino which is the size of a postage stamp. We sold the first batch we had, and by that time, the original was extinct as Dustin had moved on to another job and didn’t want to make more. We decided to respin the board with a few improvements and a smaller chip. The result of our efforts is in the shop  here .

The ExtraCoreMD, as we’re calling it, is a minuscule form factor Arduino clone, ideal for applications where space and weight need to be kept to a minimum- aircraft, robotics, fashion, wearables. The size of the board is .92″ x .825″ (21mm x 23mm), and it is manufactured on 1.3mm PCB for a sleek height profile of only .09″ (2.2mm). The board is small enough to conceal in jewelry, or DIY musical greeting cards, or wearable tech, if you’re crafty.

Programming is through our USB BUB or any standard FTDI cable, unlike the first ExtraCore. We also made one non-fatal mistake in the boards, although we are revising them immediately. The labels on the VCC and Vin are just swapped.

We cooked up a quick example app, just to prove out the board, using 18 pins (all the I/O except RX & TX) LED’s with a basic loop. Keep posted for more experiments using this board.
