MPPT: common questions
What microcontroller does the MPPT use?
The MPPT is built around the ARDUINO_NANO, from the AVR/Arduino family.
How big is the MPPT PCB?
The MPPT measures 90.4 × 69.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MPPT?
93 components, from 55 distinct parts. The full bill of materials is listed on this page.
Where can I download the MPPT design files?
From the aati106/Part-Four-Project repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MPPT design in my own project?
The repository has no license, so all rights stay with aati106. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MPPT 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.
