• 6V - 9V operation with reverse polarity protection.
• Battery voltage monitor on A7.
• Serial Communications / Bluetooth header.
• CP2102 USB serial interface with Mini-B USB socket and 500mA PTC fuse.
• Built in power Switch and Reset button.
• Digital pins on servo compatible 3 pin headers with selectable voltage (+Battery or +5V).
• Analog pins on servo compatible 3 pin headers with +5V and Gnd to power sensors.
• D13 LED.
• ISP header.
• Mounting holes are 50mm x 25mm (aprox. 2" x 1") can use 3mm or 1/8th screws.

Bluetooth Compatible

• S4A has fixed pin assignments so the pin arrangement of the PCB had to be changed to suit the S4A software. As you can see in the photo below, the DAGU Bluetooth module fits neatly on top allowing your robots to remain in contact with the S4A software on your PC as they roam about. I've tested the controller using both Windows XP and Windows 7.
