Solar mppt1: common questions
What microcontroller does the Solar mppt1 use?
The Solar mppt1 is built around the ATmega32U4RC-AU, from the AVR/Arduino family.
How big is the Solar mppt1 PCB?
The Solar mppt1 measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Solar mppt1?
133 components, from 59 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 Solar mppt1 design files?
From the reivax-boucoi/PCB_Kicad 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 Solar mppt1 design in my own project?
The repository has no license, so all rights stay with reivax-boucoi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Solar mppt1 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.
