Oven2: common questions
What microcontroller does the Oven2 use?
The Oven2 is built around the esp32-wroom-32u, from the ESP32 family.
How big is the Oven2 PCB?
The Oven2 measures 75 × 160 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Oven2?
47 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Oven2 design files?
From the bybzmt/practise repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Oven2 design in my own project?
The repository has no license, so all rights stay with bybzmt. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Oven2 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.
