LORA: common questions

What microcontroller does the LORA use?

The LORA is built around the RP2040, from the RP2040/RP2350 family.

How big is the LORA PCB?

The LORA measures 35.2 × 37 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LORA?

50 components, from 31 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 LORA design files?

From the v1m08/LORA 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 LORA design in my own project?

The repository has no license, so all rights stay with v1m08. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LORA without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
