About the Linux soc PCB

Linux soc is an open source AVR/Arduino PCB design by NEOgHacking, published on GitHub. It is a 4-layer board measuring 25.5 × 32 mm, with 73 components from 28 distinct parts.

Its main chip is the ATMEGA328P-MM, from the AVR/Arduino family. Other key parts include the F1C100S, TMI7003C and CH343P. By type, the board carries 37 capacitors, 21 resistors, 4 ICs, 4 connectors, 3 inductors and 2 crystals.

Linux soc: common questions

What microcontroller does the Linux soc use?

The Linux soc is built around the ATMEGA328P-MM, from the AVR/Arduino family.

How big is the Linux soc PCB?

The Linux soc measures 25.5 × 32 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Linux soc?

73 components, from 28 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 Linux soc design files?

From the NEOgHacking/linux_soc 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 Linux soc design in my own project?

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

Can I test firmware for the Linux soc 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.
