LoRaPill: common questions
What microcontroller does the LoRaPill use?
The LoRaPill is built around the STM32F103RCTx, from the STM32 family.
How big is the LoRaPill PCB?
The LoRaPill measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LoRaPill?
32 components, from 22 distinct parts. The full bill of materials is listed on this page.
Where can I download the LoRaPill design files?
From the cristobalcuevas/PCB-Designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the LoRaPill design in my own project?
The repository has no license, so all rights stay with cristobalcuevas. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the LoRaPill 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.
