Programmable-Load: common questions
What microcontroller does the Programmable-Load use?
The Programmable-Load is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the Programmable-Load PCB?
The Programmable-Load measures 99.1 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Programmable-Load?
33 components, from 23 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 Programmable-Load design files?
From the ketszim97/Programmable-Load repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Programmable-Load design in my own project?
The repository has no license, so all rights stay with ketszim97. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Programmable-Load 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.
