What microcontroller does the HCS-12SS59T-HW use?

The HCS-12SS59T-HW is built around the ESP32-wroom-32, from the ESP32 family.

How big is the HCS-12SS59T-HW PCB?

The HCS-12SS59T-HW measures 101.5 × 25.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HCS-12SS59T-HW?

60 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the HCS-12SS59T-HW design files?

From the Jana-Marie/HCS-12SS59T-HW repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the HCS-12SS59T-HW design in my own project?

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

Can I test firmware for the HCS-12SS59T-HW 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.
