Code
This is my github pages repo, viewable at ehryk.github.io. It also has some setup files that I sync between various computers, most notably git and bash aliases.
These are the settings I sync between various computers. Update Config.bat for windows, update-config.sh for linux.
Custom Rainmeter skins for GPU and CPU temps, etc.

ESPRadiator: common questions
What microcontroller does the ESPRadiator use?
The ESPRadiator is built around the ESP32-DEVKIT-V1, from the ESP32 family.
How big is the ESPRadiator PCB?
The ESPRadiator measures 50 × 57 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESPRadiator?
49 components, from 40 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 ESPRadiator design files?
From the Ehryk/ehryk.github.com 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 ESPRadiator design in my own project?
Yes, under the terms of its BSD-3-Clause license, which Ehryk chose for the repository.
Can I test firmware for the ESPRadiator 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.
