With this MySensors node you can turn on/off 3 USB type A ports; the power state of each USB port can be controlled in two ways:

• With the dedicated physical push button
• In a “smart” way through the Home Assistant WebUI

The node is useful in many situations, like charging your smartphone, powering a Raspberry Pi or any other USB devices with the added value to manage or automate the process in your home automation hub.

It is built with the Mini-BT-pcb-328p board (mother board) and the USB-exp pcb (daughter board) all enclosed in a 3d printable case.

The Mini-BT-pcb-328p board supports both radio modules: RFM69 (868 Mhz) and NRF24 (THT and SMD), while The USB-Exp PCB, that feeds also the Mini-BT-pcb-328p board, has two connector for the external power.

• 1 micro USB port (5V DC)
• 1 Power jack (5-12V DC)

The optional buck converter present after the power jack allows you to power the board with a voltage range of 5-12V and with the Jumper JP1 you can bypass it, feeding the USB ports directly with your input voltage.
