Edge-Computing-Motion PCB

A custom 2-layer edge-computing printed circuit board designed for motion sensing, localized signal processing, and low-latency I2C sensor communication.

Project Overview

The Edge-Computing-Motion PCB integrates an Inertial Measurement Unit (IMU), power distribution network, and high-speed communication lines onto a compact 2-layer board. Designed using KiCad, the layout accounts for strict manufacturing tolerances, signal integrity, and isolated ground plane return paths.

Key Specifications

Board Dimensions / Layers: 2-Layer FR4 (F.Cu, B.Cu)
Power Input: +5V via USB-C / External header, stepping down to +3.3V (/3V3)
Core Sensor: High-precision IMU (U3) connected via I2C bus (SDA / SCL)
Design Rules: 0.20 mm min trace/space clearance, 0.30 mm drill min size
Connector: USB-C connector (J1) for power and data transport

Questions

How big is the Edge Computing Motion PCB?

It measures 61.5 × 39 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Edge Computing Motion use?

32 parts, built around the ESP32-S3-WROOM-1-N8, AP2112K-3.3 and MPU-6050. 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 Edge Computing Motion KiCad files?

From the gehadgad2019/Edge-Computing-Motion-PCB repository on GitHub, at the commit this page was made from: the board is Edge-Computing-Motion.kicad_pcb and its schematic Edge-Computing-Motion.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Edge Computing Motion design in my own project?

Its repository states no licence, so its author keeps all rights: ask gehadgad2019 before reusing the design.
