Uamsense: common questions

What microcontroller does the Uamsense use?

The Uamsense is built around the ESP32-WROOM, from the ESP32 family.

How big is the Uamsense PCB?

The Uamsense measures 69.7 × 95.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Uamsense?

72 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Uamsense design files?

From the GNB-UAM/UAMSense repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Uamsense design in my own project?

Yes, under the terms of its GPL-3.0 license, which GNB-UAM chose for the repository.

Can I test firmware for the Uamsense 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.
