The KiCad project lives in the ep092/TX5823 repository on GitHub; these links point at the commit this page was built from.

TX5823: common questions

What microcontroller does the TX5823 use?

The TX5823 is built around the ATMEGA328P-A, from the AVR/Arduino family.

How big is the TX5823 PCB?

The TX5823 measures 54.5 × 47.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TX5823?

94 components, from 62 distinct parts. The full bill of materials is listed on this page.

Where can I download the TX5823 design files?

From the ep092/TX5823 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TX5823 design in my own project?

The repository has no license, so all rights stay with ep092. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TX5823 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.
