### DESCRIPTION

This is a versatile usb device. It has an AVR AT90USB162 microcontroller and an ESP8266 ESP-12 module, both of them connected by serial bus. You can program each one individually to achive amazing usb-remote applications (i.e: remote keyboard and mouse, virtualized storage, robot control, domotics...). The limits are only in your imagination.

### LEARN / TOPIC / BUILD INSTRUCTIONS

The AVR microcontroller can be programmed with an ICSP-compatible tool like AVR MKII, AVR Dragon, etc.

The ESP-12 module can be programmed with an usb2serial device. Only remove the jumpers RX and TX and insert one in PRG, then connect GND, TX and RX pins to usb2serial device and power on the system. However there is already an AT firmware loaded into the module to do the vast majority of wifi actions.

It is highly recommended to use the LUFA library for programming USB on AVR.
