Lcd square-4inch: common questions

What microcontroller does the Lcd square-4inch use?

The Lcd square-4inch is built around the STM32H743IITx, from the STM32 family.

How big is the Lcd square-4inch PCB?

The Lcd square-4inch measures 73.5 × 68 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Lcd square-4inch?

103 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lcd square-4inch design files?

From the rohamid/lcd-east-rising-backpack repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lcd square-4inch design in my own project?

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

Can I test firmware for the Lcd square-4inch 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.
