👋 Welcome to the WLED Wemos board shield wiki!

➡️ How to start?

1. Choose options that are suitable for you
   
   You can also go on without choosing an option but then you only have bare minimum functionality
   See: What can I do with bare minimum?

2. Order PCB

3. Order all parts you need

4. Assemble all components to the PCB

5. Check if everything is working fine

6. Flash Firmware for D1 mini or ESP32 mini

7. Optionally: Put your stuff in a enclosure

If you need help with something or have questions feel free to ask.

🚀 Overview

0. If somebody lost a trace - Bill of materials.
1. Very easy to assemble due to use of thru hole parts. No need to deal with SMD parts.
2. Relay is used to reduce energy consumption.
3. Fused LED power output and Development board power input.
4. Can be used with 2 types of development boards Wemos D1 mini and ESP32 D1.
5. Various configurations to use for different purposes and different types of LED strip.
6. User can choose between precompiled binary and compile his own.
