    Flyduino‐A 12 Servo Controller(SKU:DFR0136) Contents    1 Introduction 1.1 Specification 2 Pin Diagram 3 Sample Code Introduction This is probably the smallest Arduino controller speically designed for controlling servos. It features a 12 standard servo control capbility with an Xbee socket which can be used in model helicopters or UAVs via the Xbee link. The feather weight (7.5g) makes it an ideal controller for application with a limited payload. The built in regulator allows the input voltage to vary from 3.5-8V which fits most power supplies without any modification. Note: A FTDI Basic breakout is required to upload the program (@3.3V) Warning: The controller is working under 3.3V, please do not program it with a 5V FTDI breakout, it will damage the module permanently. Specification          CPU:Atmega328P Working voltage:3.3V Input voltage:3.5-8V (regulated) 12 Channel servo control Xbee socket Analog input: 8 SRAM:2K EEPROM:1K Weight:7.5 gram Pin Diagram Pin Diagram for DFlyduino NOTE: Pin "RX" and pin "TX" are on the left side, FTDI interface Sample Code #include #define NBR_SERVOS 12 er boards // the number of servos, up to 48 for Mega, 12 for oth #define FIRST_SERVO_PIN 2 MegaServo Servos[NBR_SERVOS] ; // max servos is 48 for mega, 12 for other boa rds int pos = 0; // variable to store the servo position int potPin = 0; // connect a pot to this pin. void setup() { for( int i =0; i < NBR_SERVOS; i++) Servos[i].attach( FIRST_SERVO_PIN +i, 800, 2200); } void loop() { pos = analogRead(potPin); // read a value from 0 to 1023 for( int i =0; i
