UBMP4.1: common questions

What microcontroller does the UBMP4.1 use?

The UBMP4.1 is built around the PIC16F1459-IP, from the PIC family.

How big is the UBMP4.1 PCB?

The UBMP4.1 measures 88.9 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UBMP4.1?

56 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the UBMP4.1 design files?

From the mirobotech/UBMP4.1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the UBMP4.1 design in my own project?

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

Can I test firmware for the UBMP4.1 without the hardware?

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