Yesterday I added:
- Femtoduino: Fabio Varesano's tiny 328-based board with .05" pin pitch.
- Menta by Adafruit fits in an Altoids tin, has a prototyping area and is shield-compatible!
- Minuino is another fine Spikenzie Labs Arduino-compatible board with as few components as possible and the smallest footprint to accommodate shields.
- ReaDIYmate is a Kickstarter project which Seeed is pre-selling, including WiFi, MP3 decoding, a MicroSD slot, and audio amplifier... wow! BUT:
the Kickstarter isn't funded yet! Go support this cool board!!Update 4/26/12: I did!! Update 4/29/12: It got funded! $27,143 of the $25K goal, excellent!!
