Ultisense: common questions
What microcontroller does the Ultisense use?
The Ultisense is built around the C2913202, from the ESP32 family.
How big is the Ultisense PCB?
The Ultisense measures 44.7 × 93.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Ultisense?
83 components, from 41 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 Ultisense design files?
From the darshg321/Ultisense 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 Ultisense design in my own project?
The repository has no license, so all rights stay with darshg321. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ultisense 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.
