Hat board: common questions

What microcontroller does the Hat board use?

The Hat board is built around the ).96 inOLED display SSD1306, from the ESP32 family.

How big is the Hat board?

The Hat board measures 73.2 × 99.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hat board?

79 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hat board design files?

From the Phil-CIA/Captain-Fantastic-home-edition repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Hat board design in my own project?

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

Can I test firmware for the Hat board 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.
