HB-UNI-644: common questions
What microcontroller does the HB-UNI-644 use?
The HB-UNI-644 is built around the CP2102N, from the AVR/Arduino family.
How big is the HB-UNI-644 PCB?
The HB-UNI-644 measures 79 × 78 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the HB-UNI-644?
64 components, from 47 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 HB-UNI-644 design files?
From the alexreinert/PCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the HB-UNI-644 design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the HB-UNI-644 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
