Main test: common questions
What microcontroller does the Main test use?
The Main test is built around the ESP32-C6-WROOM-1-N4, from the ESP32 family.
How big is the Main test PCB?
The Main test measures 54 × 71 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Main test?
194 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the Main test design files?
From the 0x63616c/smart-blinds repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Main test design in my own project?
The repository has no license, so all rights stay with 0x63616c. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Main test 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.
