Its main chip is the TMC2130-LA-T, from the STM32 family. By type, the board carries 5 connectors, 4 capacitors, 4 resistors, 3 ICs, 1 switch and 1 diode.

From the project

Cool Hardware designed by the Voron Design group

This is a dedicated board to drive a FYSETC Mini 12864 Display. It's intended to run the Klipper firmware.

The intention is to reduce the number of wires to connect your display to your VORON. No ribbon cables are required, you can plug this directly onto the back of your screen and then use a single microUSB cable to your Raspberry Pi.

The Nano Display came first, and yes, it does a similar thing. And yeah, it's easier to build, and it's likely cheaper. It's not a bad option.

Stm32-mini12864: common questions

What microcontroller does the Stm32-mini12864 use?

The Stm32-mini12864 is built around the TMC2130-LA-T, from the STM32 family.

How big is the Stm32-mini12864 PCB?

The Stm32-mini12864 measures 42.7 × 13.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32-mini12864?

18 components, from 15 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 Stm32-mini12864 design files?

From the VoronDesign/Voron-Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Stm32-mini12864 design in my own project?

Yes, under the terms of its GPL-3.0 license, which VoronDesign chose for the repository.

Can I test firmware for the Stm32-mini12864 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.
