RITHESH LED Display: Version 2 (rev 0.2, proposal)

Proposal only. Do not order. Version 1 (the project root) is the approved prototype and is not changed here. The Version 2 LED (XL-2020RGBC-2812B) is provisional until its own WLED timing test passes.

Version 2 is a smaller board:

  • 250 × 40 mm instead of 300 × 70 mm
  • 107 small 2 × 2 mm LEDs at 5 mm spacing
  • the electronics at the right end of the word

The ESP32, WLED, protection chips, buttons, test pads and mounting holes stay the same.

File What it is
requirements.md All Version 2 decisions, LED and timing checks, power numbers, risks, parts changes and the V1 vs V2 comparison
hardware/rithesh_v2_fp.pretty/ New LED footprint LED_XL-2020RGBC-2812B (from the datasheet's recommended pattern)
hardware/layout-plan/ Proposed LED pattern (1:1 SVG), board plan, electronics-area plan, footprint drawing
hardware/tools/ Scripts that generate the footprint, the plan drawings and the WLED maps (make_v2_footprint.py, make_v2_plan.py, make_v2_ledmaps.py)
firmware/ Version 2 WLED maps (ledmap.json, ledmap1.json) and led-order.csv. The LED numbering changed: V2 LED1 is at the right end (see firmware/README.md)

Not created yet (waiting for approval): schematic, PCB placement and routing, manufacturing files, full V2 setup guide.
