Nano development board, with CH340G USB converter and miniUSB.

Nano R3 is ideal for your projects
Nano R3 has a CH340 or CH341 on-board chip in place of the component Atmega16U2 chip which allows communication with a USB cable.

Depending on your operating system, the CH340 chip often requires a driver that you will find in the "attached documents" tab as well as a tutorial in French for its installation.
This board is an "open-source" microcontrolled prototyping platform specially designed for artists, designers or hobbyists. This version is built around an ATmega328p microcontroller associated with a USB interface.
All the inputs / outputs of the board are available on female connectors on the edges of the board.
Programmable via a language close to "C" (available for free download), this card can operate autonomously or by communicating with software "running" on a computer (Flash, MaxMSP ...).
