LoRaWAN-Feather-Hardware: common questions

What microcontroller does the LoRaWAN-Feather-Hardware use?

The LoRaWAN-Feather-Hardware is built around the STM32L073CZTx, from the STM32 family.

How big is the LoRaWAN-Feather-Hardware PCB?

The LoRaWAN-Feather-Hardware measures 63.5 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LoRaWAN-Feather-Hardware?

82 components, from 47 distinct parts. The full bill of materials is listed on this page.

Where can I download the LoRaWAN-Feather-Hardware design files?

From the svcguy/LoRaWAN-Feather-Hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the LoRaWAN-Feather-Hardware design in my own project?

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

Can I test firmware for the LoRaWAN-Feather-Hardware without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
