GOLMain RevA: common questions

What microcontroller does the GOLMain RevA use?

The GOLMain RevA is built around the ESP8266-12E, from the ESP8266 family.

How big is the GOLMain RevA PCB?

The GOLMain RevA measures 70 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GOLMain RevA?

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

Where can I download the GOLMain RevA design files?

From the gatechipdl/GameOfLight repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the GOLMain RevA design in my own project?

Yes, under the terms of its MIT license, which gatechipdl chose for the repository.

Can I test firmware for the GOLMain RevA without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
