Kicad agent suite: common questions
What microcontroller does the Kicad agent suite use?
The Kicad agent suite is built around the ESP32-S3-WROOM-1-N8R8 module, from the ESP32 family.
How big is the Kicad agent suite PCB?
The Kicad agent suite measures 196 × 182 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Kicad agent suite?
62 components, from 35 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Kicad agent suite design files?
From the 11cookies11/kicad-agent-suite repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Kicad agent suite design in my own project?
Yes, under the terms of its MIT license, which 11cookies11 chose for the repository.
Can I test firmware for the Kicad agent suite 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.
