UPLC-Analog: common questions

What microcontroller does the UPLC-Analog use?

The UPLC-Analog is built around the ESP32-C3-WROOM-02-N4, from the ESP32 family.

How big is the UPLC-Analog PCB?

The UPLC-Analog measures 31.4 × 22 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the UPLC-Analog?

48 components, from 19 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 UPLC-Analog design files?

From the fredriknk/uPLC-Analog 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 UPLC-Analog design in my own project?

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

Can I test firmware for the UPLC-Analog 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.
