Energy Meter: common questions
What microcontroller does the Energy Meter use?
The Energy Meter is built around the TEENSY_3.5, from the NXP family.
How big is the Energy Meter PCB?
The Energy Meter measures 45.7 × 39.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Energy Meter?
33 components, from 25 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 Energy Meter design files?
From the UNCAMotorsports/UNCAMotorsports-2017 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Energy Meter design in my own project?
Yes, under the terms of its MIT license, which UNCAMotorsports chose for the repository.
Can I test firmware for the Energy Meter without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
