LoRa STM32 Board: common questions
What microcontroller does the LoRa STM32 Board use?
The LoRa STM32 Board is built around the STM32L072CBT6, from the STM32 family.
How big is the LoRa STM32 Board?
The LoRa STM32 Board measures 51.6 × 56 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the LoRa STM32 Board?
81 components, from 55 distinct parts. The full bill of materials is listed on this page.
Where can I download the LoRa STM32 Board design files?
From the collins-emasi/KiCAD-PROJECTS-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the LoRa STM32 Board design in my own project?
The repository has no license, so all rights stay with collins-emasi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the LoRa STM32 Board 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.
