Battery: common questions
What microcontroller does the Battery use?
The Battery is built around the SN65HVD230, from the ESP32 family.
How big is the Battery PCB?
The Battery measures 79 × 90.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Battery?
11 components, from 10 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 Battery design files?
From the Monash-Railway-Express/KiCad_Files repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Battery design in my own project?
The repository has no license, so all rights stay with Monash-Railway-Express. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Battery without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
