TheraPatch design files

The KiCad project lives in the noahalam77-code/TheraPatch repository on GitHub; these links point at the commit this page was built from.

TheraPatch: common questions

What microcontroller does the TheraPatch use?

The TheraPatch is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the TheraPatch PCB?

The TheraPatch measures 61.3 × 61.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TheraPatch?

82 components, from 43 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 TheraPatch design files?

From the noahalam77-code/TheraPatch 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 TheraPatch design in my own project?

Yes, under the terms of its MIT license, which noahalam77-code chose for the repository.

Can I test firmware for the TheraPatch 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.
