This page will provide an overview of everything on the current iteration of the Controls Lighting Board, including both features in-use as well as deprecated features and reasoning behind deprecation.

Full Board Layout:
| Section | Schematic View | Layout View (attention to highlighted section) | What does this do? |
|---|---|---|---|
| Main |
|  | • LM555xM is a timer, used to blink left and right blinkers • diodes D6 and D7 will direct current to either right or left blinker depending on switch connection |
| Power Distribution - 5V Power |
|
| • Power On diode flashes an LED when board is on • NCP1117 - voltage regulation for the board, capacitors provide additional regulator stability because of distance from power source (*where is the power source?) • 5V power supply |
| Power Distribution - 12V Power |
|
| • 12V power supply • CSD185 - N-channel MOSFET that regulates amount of current flow • PWR_Flag raised dependent on whether connected to power or ground (*not totally sure) • SOD323 - Zener Diode, allows current to flow backwards (*why is that needed here?) |
| MinionConn |
|
| • Plugs into other board that enables lights and buttons for brake, forward, reverse, and cruise |
| Inputs and Switches - Cruise Set |
|
| • indicator for setting cruise control |
| Inputs and Switches - Regen Enable |
|
| • Indicator for enabling regen braking |
| Inputs and Switches - Cruise Enable |
|
| • Indicator for enabling cruise control |
| Inputs and Switches - Car mode Set |
|
| • Indicator for car mode (forward, reverse, neutral) |
| Lights - Brakelight |
|
| • Turns on brakelight • *What is GNDPWR and why does it connect to the external lights? (for all lights) • (for brakelight and blinkers) SI8261ABC (gate driver) and 2N7002 (MOSFET) used to regulate current to external lights |
| Lights - Headlight |
|
| • Turns on headlights |
| Lights - Left and Right Blinkers |
|
| • Turns on left or right blinkers (both internal and external) |
