This is a WLED board built around an ESP-8285, designed to be milled on a CNC.

Parts include the ESP8285, a PCB trace antenna, an optional external antenna connector, CH340K USB controller (with support for ESP auto-programming), TXS0101 level shifter, an ME3115 buck converter (for WS2811 projects), and a ME6211 3.3V LDO. This stuff is, for the most part, straight out of the data sheets so there shouldn't be anything too exciting.

There's no real attempt to do any antenna tuning, impedance matching, etc. I used the D1 mini pro as a guideline and basically cross my fingers.
