BOX-2252: common questions
What microcontroller does the BOX-2252 use?
The BOX-2252 is built around the ArduinoProMini, from the AVR/Arduino family.
How big is the BOX-2252 PCB?
The BOX-2252 measures 50.5 × 70 mm, has 2 copper layers and is 1.2 mm thick.
How many components are on the BOX-2252?
60 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the BOX-2252 design files?
From the fallberg/MySensorsNode repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BOX-2252 design in my own project?
Yes, under the terms of its CERN-OHL-1.2 license, which fallberg chose for the repository.
Can I test firmware for the BOX-2252 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
