Sunrise clock main board: common questions
What microcontroller does the Sunrise clock main board use?
The Sunrise clock main board is built around the ESP32-DevKitC, from the ESP32 family.
How big is the Sunrise clock main board?
The Sunrise clock main board measures 160 × 106.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Sunrise clock main board?
124 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the Sunrise clock main board design files?
From the atoomnetmarc/Sunrise-clock repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Sunrise clock main board design in my own project?
Yes, under the terms of its Apache-2.0 license, which atoomnetmarc chose for the repository.
Can I test firmware for the Sunrise clock main 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.
