BatteryManagementUnit: common questions
What microcontroller does the BatteryManagementUnit use?
The BatteryManagementUnit is built around the Teensy_3.2, from the NXP family.
How big is the BatteryManagementUnit PCB?
The BatteryManagementUnit measures 0.1 × 0.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BatteryManagementUnit?
68 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the BatteryManagementUnit design files?
From the EV-Project/BatteryManagementUnit repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BatteryManagementUnit design in my own project?
The repository has no license, so all rights stay with EV-Project. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BatteryManagementUnit 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.
