This is a look at the pieces that make up the micro controller. At the very top of the photo is the volt meter. Slightly to the right and down is the front panel with the LCD and the LED indicators. Below that is the STAMP carrier board with the serial cable connected and the 9v battery. To the right is the motor controller that drives the solar panel tracking motor. The large white DB25 cable is the connection to the relays mounted at the top of the tower. Also visible are the manual controls, 3 push buttons and a rocker switch for the solar panel.
