1. PDU design files

The KiCad project lives in the SshgurkiratSingh/CCMS_PORTAL repository on GitHub; these links point at the commit this page was built from.

1. PDU: common questions

What microcontroller does the 1. PDU use?

The 1. PDU is built around the ATmega8-16A, from the AVR/Arduino family.

How big is the 1. PDU PCB?

The 1. PDU measures 149.5 × 113 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the 1. PDU?

106 components, from 56 distinct parts. The full bill of materials is listed on this page.

Where can I download the 1. PDU design files?

From the SshgurkiratSingh/CCMS_PORTAL repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 1. PDU design in my own project?

The repository has no license, so all rights stay with SshgurkiratSingh. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 1. PDU 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.
