Output.v25Panel: common questions
What microcontroller does the Output.v25Panel use?
The Output.v25Panel is built around the ESP32_WROOM32_SKINNY, from the ESP32 family.
How big is the Output.v25Panel PCB?
The Output.v25Panel measures 100 × 100 mm and is 1.6 mm thick.
How many components are on the Output.v25Panel?
45 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Output.v25Panel design files?
From the maholli/SAM32 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Output.v25Panel design in my own project?
The repository has no license, so all rights stay with maholli. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Output.v25Panel 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.
