Hardware design, BOM, gerbers and 3D files for Dasduino-LITE designed by Soldered Electronics.

Dasduino Lite is the right choice when you are limited with space, but still looking for capable controller. Based on Attiny1604, with USB-C port, Li-ion charger and CH340 USB-UART converter, it has all must-haves on a small form-factor.

Only 38mm wide and 26mm high, Dasduino Lite contains 12 GPIO pins. Of these, 9 can be programmed as analog. It comes with a USB Type-C connection and is 100% compatible with the original Arduino IDE software using custom Board Definition. In addition to its small dimensions, which are the main characteristic of this Dasduino, there is also a charger for a…
