Breadboard-only version (no custom PCB) + guide (post-launch)

Breadboard-only Version (No Custom PCB) Guide Test Run

This comment logs the initial test run for the breadboard-only assembly workflow. A more polished, comprehensive, and beginner-friendly guide will be officially added post-launch.

• Total Time Required: 1 hour 30 minutes

⚠️ Friction Points & Action Items

• Issue: Relying solely on text-based pin maps or traditional circuit schematics made the assembly process quite difficult and counter-intuitive.
• Solution required: There is a clear need for intuitive visual wiring diagrams or pictorial layouts (such as Fritzing-style graphics) that explicitly show exactly which wire goes into which pin to improve readability.

To-do:

• Create Fritzing-style visual wiring diagrams for the final guide
• Refine text-based pin maps to be more readable
• Publish the polished, beginner-friendly official guide post-launch

📋 Step-by-Step Test Log

Step 1	Step 2	Step 3
Detach the breadboard power and ground rails, then connect all encoder grounds.	Strip the USB cable coating and connect it to the LED panel power line and the + and - terminals on the breadboard.	Connect the HUB75E and ESP32 DevKit according to the pin map.
Step 4	Step 5	Step 6
Check the pin map for the encoders and connect them in the order of A, B, and SW (this sequence is recommended).	Cover with the case to conceal the internal components.	Cover with the case to conceal the internal components.
