# esp-idf-usb-switch

Turning USB ON/OFF using ESP-IDF.   

We can obtain products that turn USB on/off with a remote control about $4.   

Both of these use a frequency of 433MHz radio signal.   

Using these, you can turn on/off the USB device from the ESP32.   

__The product on the right has only one button, so ON/OFF may not work as expected.__

# Software requirements

ESP-IDF V5.0 or later.   

ESP-IDF V4.4 release branch reached EOL in July 2024.   

# Hardware requirements

This project supports these wireless transceivers.   

- Wireless transmitter   

H34A-315/H34A-433   

SYN115   

STX882   

- Wireless receiver   

H3V3/H3V4   

SYN480R   

LR43B/LR33B   

SRX882/SRX887   

- Wireless RF Remote Control Switch   

I used these transceivers.

# How to use

First, do teaching.   

The teaching results are stored in NVS.   

Turn the USB ON/OFF using the teaching results.   

# Teaching

```

git clone https://github.com/nopnop2002/esp-idf-usb-switch

cd esp-idf-usb-switch/teaching

idf.py menuconfig

idf.py flash

```
