Power: common questions

What microcontroller does the Power use?

The Power is built around the PIC18F26K80_ISS, from the PIC family.

How big is the Power PCB?

The Power measures 125 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power?

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

Where can I download the Power design files?

From the mbouyer/weatherstation repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Power design in my own project?

Yes, under the terms of its BSD-2-Clause license, which mbouyer chose for the repository.

Can I test firmware for the Power without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
