Description​

We built an electric skateboard with the battery pack, longboard deck, and electronics enclosure assembled in-house! On top of the core project, we designed its own power distribution, telemetry, and lighting systems. Throughout the term, our team members developed experience across the board by applying key technical skills from CAD in SolidWorks, across schematic capture & PCB layout in KiCad, to embedded C code on ESP32 & AVR.

Longboard Deck​

9-layer maple veneer set vacuum pressed with a foam mold. Skateboard deck and mold modelled in SolidWorks prior to fabrication. Skateboard Picture 6 Skateboard Picture 7 Skateboard Picture 8

Electronics Enclosure​

3D printed after optimizing SolidWorks model to pass height & weight clearances while housing all electronics, including the battery pack, VESC, power distribution, telemetry, and wiring harness.

Power Distribution​

2-stage power delivery using buck converters with a robust input protection circuit. Safely steps down the battery pack voltage from 43.2 V to 12 V to 3.3 V, feeding the head & tail lights and lighting control & telemetry MCUs, respectively. PCB designed in KiCad.

Telemetry​

ESP32 displays key vehicle metrics in real-time to both an on-board OLED display and a phone through BLE. Communicates with VESC & BMS through UART. PCB designed in KiCad.

Lighting​

Vehicle-grade head & tail lights controlled by an ATMega328P programmed in bare-metal C. Each unit features multiple distinct lighting modes, including a mode for accelerometer-guided brake lights.
