This is an SDR custom shield designed for the Arduino Mega 2560 microcontroller. It's designed to provide easy access to the board's I/O pins without compromising the ability to connect additional shields. All the surface mount components are mounted. The through hole headers and components need to be soldered in or you can select for us to assemble it below.

Note: This shield includes 16 solder jumpers (prefixed SJ on the board) that we are populating with 0 ohm resistors. The functions of these jumpers are described below; feel free to remove select jumpers if you don't want the functionality.

• SJ1: Connects Vin to the analog 0 voltage divider input for the purpose of monitoring the input voltage
• SJ16: Shorts the Servo 5V power rail to the shield's 5V regulator output. If this jumper is opened, you can put your own power source on the Servo Pwr header.
• SJ2 - SJ15: Adds a 0.1 uF filtering capacitor between the respective analog pin and ground
