Overview

AIL is an open-source printed circuit board by michaelruppe, from the michaelruppe/FSAE repository on GitHub, published under the MIT licence. It is a 2-layer board with 16 parts on 9 nets.

It is built around the LR8K4-G. Its parts include 5 resistors, 3 capacitors, 3 diodes, 2 ICs and 2 connectors.

TSAL

A light that indicates presence of dangerous voltage within the Tractive System

The third iteration of the TSAL driver.

Watch a video walkthrough explaining the circuit operation and design decision.

A device to precharge the Tractive System. This prototype features voltage feedback to protect AIRs. In open-loop systems, if a wiring fault develops - eg. precharge resistor is disconnected - then the precharge is ineffective and AIRs may become damaged.

The prototype Precharge module

HFL (Hard Fault Latch)

Latches momentary faults that are required to shutdown the EV.

Questions

What parts does the AIL use?

16 parts, built around the LR8K4-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the AIL KiCad files?

From the michaelruppe/FSAE repository on GitHub, at the commit this page was made from: the board is AIL/AIL.kicad_pcb and its schematic TSALv3/TSALv3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the AIL design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
