RoProp: common questions

What microcontroller does the RoProp use?

The RoProp is built around the STM32F103C8Tx, from the STM32 family.

How big is the RoProp PCB?

The RoProp measures 75.6 × 65.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RoProp?

85 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the RoProp design files?

From the embeddedalpha/PCB-Design repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the RoProp design in my own project?

Yes, under the terms of its MIT license, which embeddedalpha chose for the repository.

Can I test firmware for the RoProp 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.
