Jaanus has been working on a subminiature Arduino clone which be believes is THE smallest.
Everybody are making Arduino clones. So I thought I should make THE smallest. I took smallest package atmega88 – qnf28 (5mm x 5mm). Routed smallest possible resonator and as much pads as i could fit on in.
His design provides SPI, UART, one LED and breaks out 4 analog and 1 digital IO pins.
Check out Projects of Jaanus for project details, design files and related docs.
Cool! Less is so much more!
I’m looking forward to see the pictures.
Cool, While not great for clock stability but why not use the internal resonator?
Nice, can I buy these anywhere?
