BATDATUNIT01: common questions
What microcontroller does the BATDATUNIT01 use?
The BATDATUNIT01 is built around the ATMEGA1284P-AU, from the AVR/Arduino family.
How big is the BATDATUNIT01 PCB?
The BATDATUNIT01 measures 136.2 × 85.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BATDATUNIT01?
206 components, from 74 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the BATDATUNIT01 design files?
From the mlab-modules/BATDATUNIT01 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the BATDATUNIT01 design in my own project?
