GMote Mini: common questions
What microcontroller does the GMote Mini use?
The GMote Mini is built around the ATmega328P-AU, from the AVR/Arduino family.
How big is the GMote Mini PCB?
The GMote Mini measures 33.8 × 24.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the GMote Mini?
21 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the GMote Mini design files?
From the hackdaworld/gmote repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the GMote Mini design in my own project?
Yes, under the terms of its GPL-3.0 license, which hackdaworld chose for the repository.
Can I test firmware for the GMote Mini 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.
