Arduino pro mini shield

Design by: 5496

This board is an arduino pro mini shield with two power supply's. Both 3.3V and 5v. Furthermore on the board are two pull-ups for I2C and two 2n2222 NPN transistors connected to pin D3 and D5 to switch something That needs more current then the pins from the pro mini can supply. The 2n2222 is rated 800mA. The board itself is easier to use than the pro-mini stand allone. It Will give you almost the flexibility as the uno board. The only additional part you need is a cp2102 usb to serial to program the board This board will enable you to leave a cheap arduino in your stand allone project and use it as testing platform.
