DCDC Power Control: common questions
What microcontroller does the DCDC Power Control use?
The DCDC Power Control is built around the ATtiny414-SS, from the AVR/Arduino family.
How big is the DCDC Power Control PCB?
The DCDC Power Control measures 46 × 81 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DCDC Power Control?
76 components, from 35 distinct parts. The full bill of materials is listed on this page.
Where can I download the DCDC Power Control design files?
From the pilotniq/MJoulnir repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the DCDC Power Control design in my own project?
The repository has no license, so all rights stay with pilotniq. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DCDC Power Control 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.
