Kicad rfm95-breakout board: common questions

What microcontroller does the Kicad rfm95-breakout board use?

The Kicad rfm95-breakout board is built around the STM32L053R8T6, from the STM32 family.

How big is the Kicad rfm95-breakout board?

The Kicad rfm95-breakout board measures 69.2 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kicad rfm95-breakout board?

60 components, from 28 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 Kicad rfm95-breakout board design files?

From the Bamelink/kicad-rfm95-breakout-board 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 Kicad rfm95-breakout board design in my own project?

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

Can I test firmware for the Kicad rfm95-breakout 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.
