Solar lora: common questions

What microcontroller does the Solar lora use?

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

How big is the Solar lora PCB?

The Solar lora measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Solar lora?

45 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Solar lora design files?

From the mattvenn/solar-lora repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Solar lora design in my own project?

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

Can I test firmware for the Solar lora 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.
