Encoder: common questions

What microcontroller does the Encoder use?

The Encoder is built around the STM32C011F6P6, from the STM32 family.

How big is the Encoder PCB?

The Encoder measures 50 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Encoder?

57 components, from 31 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 Encoder design files?

From the Tomoshibi-technology/RCJ-Japan2024-Circuit 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 Encoder design in my own project?

Yes, under the terms of its MIT license, which Tomoshibi-technology chose for the repository.

Can I test firmware for the Encoder 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.
