Initial driver: common questions
What microcontroller does the Initial driver use?
The Initial driver is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Initial driver PCB?
The Initial driver measures 48.2 × 32.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Initial driver?
8 components, from 7 distinct parts. The full bill of materials is listed on this page.
Where can I download the Initial driver design files?
From the jediminer543/animated-robot repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Initial driver design in my own project?
Yes, under the terms of its Apache-2.0 license, which jediminer543 chose for the repository.
Can I test firmware for the Initial driver 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.
