UpsKeypadTerminal: common questions

What microcontroller does the UpsKeypadTerminal use?

The UpsKeypadTerminal is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the UpsKeypadTerminal PCB?

The UpsKeypadTerminal measures 109.2 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UpsKeypadTerminal?

39 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the UpsKeypadTerminal design files?

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

Can I use the UpsKeypadTerminal design in my own project?

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

Can I test firmware for the UpsKeypadTerminal 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.
