Boardforge ai: common questions
What microcontroller does the Boardforge ai use?
The Boardforge ai is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the Boardforge ai PCB?
The Boardforge ai measures 150 × 125 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Boardforge ai?
43 components, from 43 distinct parts. The full bill of materials is listed on this page.
Where can I download the Boardforge ai design files?
From the donnahs/boardforge-ai repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Boardforge ai design in my own project?
The repository has no license, so all rights stay with donnahs. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Boardforge ai 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.
