Automotive ESP32-S3 PCB Design
Budget: $30 – $250 USD
PCB Designer Needed – Ultra-Compact Automotive/Motorcycle BLE Control Board
I'm seeking an experienced PCB designer to develop an ultra-compact, production-ready control board for a 12V motorcycle accessory.
This product will be installed in a sealed enclosure and operate in a harsh automotive environment exposed to vibration, voltage transients, temperature changes, and electrical noise.
The primary design objective is the smallest practical PCB while maintaining reliability, low power consumption, and manufacturability.
Functional Requirements
The PCB must provide:
ESP32-S3 with BLE connectivity
3-axis motion sensing for deceleration detection
12V automotive power input with appropriate protection
Reverse polarity protection
Transient voltage suppression (TVS)
High-side switching for LED lighting control
Digital input sensing for vehicle signals
Battery voltage monitoring
Programming and test interface
OTA firmware update capability
Optimized BLE antenna layout
Design Goals
Ultra-compact PCB footprint
Low quiescent current
Automotive-grade design practices
Suitable for a fully potted IP67 enclosure
Designed for future production and assembly
Clean, well-documented schematic and layout
Deliverables
Complete schematic
PCB layout
BOM with manufacturer part numbers
Gerber files
Pick-and-place files
Assembly drawings
Design documentation
Native project files (KiCad or Altium preferred)
Preferred Experience
Automotive or motorcycle electronics
ESP32-S3 PCB design
BLE/RF layout optimization
Automotive power supply and protection circuits
High-side switching solutions
Compact PCB optimization
Design for Manufacturing (DFM)
Project Overview
The device is a BLE-enabled automotive/motorcycle controller that monitors vehicle inputs, processes motion data from an onboard accelerometer, controls LED lighting outputs, and allows user configuration through a mobile application.
The goal is to create a compact, robust, and production-ready hardware platform suitable for future expansion into additional connected vehicle accessories.
Please include examples of similar embedded or automotive PCB projects, your preferred CAD software, estimated timeline, and a brief description of your approach to creating the smallest practical production-ready design.
Preference will be given to designers with experience in automotive electronics, BLE-enabled embedded systems, and compact multilayer PCB layouts.
