UVExpose: common questions

What microcontroller does the UVExpose use?

The UVExpose is built around the STM32_Blue_Pill_DevBoard, from the STM32 family.

How many components are on the UVExpose?

41 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the UVExpose design files?

From the uxabix/UVExpose repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the UVExpose design in my own project?

Yes, under the terms of its MIT license, which uxabix chose for the repository.

Can I test firmware for the UVExpose without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
