About the RM Electronics Central Library PCB

RM Electronics Central Library is an open source STM32 PCB design by CptEdward-MP, published on GitHub. It is a 2-layer board measuring 124.5 × 78.3 mm, with 211 components from 23 distinct parts.

Its main chip is the STM32F411_BP, from the STM32 family. Other key parts include the 74HC4067, TCRT5000L and QRE1113GR. By type, the board carries 133 resistors, 35 ICs, 14 connectors, 9 transistors, 9 diodes and 4 switches.

From the project

Over time, every team also writes the same firmware again.

Over time, every team also writes the same firmware again.

Another person later writes same driver.

Even when the problem has already been solved, we often solve it again because the previous solution was never designed to be reused.

Eventually, the people who originally wrote the software graduate, projects change, and much of that experience disappears with them.

RM Electronics Central Library: common questions

What microcontroller does the RM Electronics Central Library use?

The RM Electronics Central Library is built around the STM32F411_BP, from the STM32 family.

How big is the RM Electronics Central Library PCB?

The RM Electronics Central Library measures 124.5 × 78.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RM Electronics Central Library?

211 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the RM Electronics Central Library design files?

From the CptEdward-MP/RM_Electronics_Central_Library repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RM Electronics Central Library design in my own project?

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

Can I test firmware for the RM Electronics Central Library 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.
