Led board-
About the Led board-
Led board- is an open source PCB design by n2048-creative-technology, published on GitHub under the MIT license. It is a 2-layer board measuring 98.7 × 90.9 mm, with 26 components from 15 distinct parts.
By type, the board carries 18 connectors and 8 resistors.
From the project
LED board to controll up to 8 LED strips from a XIAO ESP32-C3
KiCad 9 project for the LED driver board: a XIAO ESP32C3 carrier that buffers its eight data outputs to 5 V and hands them to eight 24 V LED segments.
Open otherworlds-v2.kicadpro. Rendered exports of the schematic and layers live in ../images/schematic/ and are regenerated with bash ../scripts-tools/export-kicad.sh`.
AHCT logic runs from 5 V and accepts 3.3 V as a valid high, so it both level shifts and buffers: the strip sees a full 5 V edge instead of the XIAO's marginal 3.3 V. The series resistor damps reflections and sits at the driver end of the line.
