This is a great beginners kit to the world of surface mount device (SMD) soldering. With a few components and 15 minutes of soldering you can produce a professional looking kit with a standard soldering iron.

Overview

Make any USB device’s power input network controllable using this DIY kit. Add your own WEMOS D1 mini to complete the package, load on Tasmota and integrate your USB devices into your network. This device passes through 5v from the input mini USB connection and a maximum of 2.5A. The WEMOS D1 mini is also powered from the incoming 5v mini USB connection

You can also use an on-board push button switch to turn the USB output on and off.

What's in the kit?

The kit contains all the components to build the shield. Note you do need to add your own WEMOS D1 mini (or compatible).

• 1 PCB

• 1 USB Type-A female PCB mount socket connector

• 1 USB Micro-B female surface mount PCB socket connector

• 1 surface mount switch

• 2 female 8 pin headers

• 1 10k SMD resistor

• 1 100k SMD resistor

• 1 NPN SMD transistor

• 1 SMD diode

Getting started

Source Tasmota from Github and configure with the following template:

{"NAME":"USB Switch","GPIO":[0,0,52,0,0,0,0,0,0,21,0,122,0],"FLAG":0,"BASE":18}

Usage example

Plug in your TV's LED strip lights into this box and have it turn on an off remotely. You can even configure Alexa to do the hard work for you.
