Wired HID to Bluetooth & mouse button macro based on esp32c3

## [Sequel](https://oshwhub.com/dnstzzx/c3-hid2)



## Introduction

to the USB HID to Bluetooth HID converter developed based on Essence esp32-c3-32s module and comes with mouse button macro function (hard-coded), it can also be used as a HID development board.

## The hardware

introduces two USB-A interfaces for connecting the mouse and keyboard, and uses ordinary GPIO+ software to simulate the USB Host PHY. The TYPE-C interface is used for power supply and chip burning/debugging (using the c3 internal usb ser/jtag), and the serial port is reserved to prevent the built-in usb ser/jtag peripheral from hanging up.

## The software
is provided by [esp32_usb_soft_host](https://github.com/sdima1357/esp32_usb_soft_host ) and [Espressif's official Bluetooth HID device routine](https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/esp_hid_device) are simply stitched together, all of which are hard-coded, please wait. Modify a version and then send the code

## The shell
is drawn according to the board on the back of which USB-A is plugged in
