Mini Ultra Pro: common questions

What microcontroller does the Mini Ultra Pro use?

The Mini Ultra Pro is built around the ATSAMD21G18A-AU, from the Microchip SAM family.

How big is the Mini Ultra Pro PCB?

The Mini Ultra Pro measures 25.4 × 55.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mini Ultra Pro?

57 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mini Ultra Pro design files?

From the robot-army/LoRaWAN_GPS repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mini Ultra Pro design in my own project?

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

Can I test firmware for the Mini Ultra Pro without the hardware?

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