Straightkeyboard: common questions

What microcontroller does the Straightkeyboard use?

The Straightkeyboard is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Straightkeyboard PCB?

The Straightkeyboard measures 368.4 × 157.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Straightkeyboard?

186 components, from 18 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 Straightkeyboard design files?

From the ArxDraco007/straightkeyboard 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 Straightkeyboard design in my own project?

The repository has no license, so all rights stay with ArxDraco007. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Straightkeyboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
