====== UPDI-3 ======

The UPDI-3, is a simple add-on board allowing the programming of the new AVR microcontroller from Microchip. The board works as bridge between the UPID target, and a serial communication. The serial communication can from different sources, eg. an [[https://www.digikey.de/product-detail/de/ftdi-future-technology-devices-international-ltd/TTL-232R-3V3/768-1015-ND/1836393|FTDI cable]] or the [[documentation:electronics:start|FTDI-USB]]. The board has been designed in [[https://kicad.org/|KiCAD]] by using the [[https://gitlab.fabcloud.org/pub/libraries/kicad|fab libraries]].
