What microcontroller does the Spot-Welder with-MCU use?

The Spot-Welder with-MCU is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Spot-Welder with-MCU PCB?

The Spot-Welder with-MCU measures 101.4 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spot-Welder with-MCU?

79 components, from 36 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 Spot-Welder with-MCU design files?

From the ANSHUMANDOCX/Spot-Welder-with-MCU 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 Spot-Welder with-MCU design in my own project?

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

Can I test firmware for the Spot-Welder with-MCU 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.
