The Spider robot controllers were designed for robots requiring a large numbers of servos

such as humanoid and hexapod style robots. Using an ATmega1280 CPU this controller is

fully compatible with the Arduino Mega (1280).

This controller includes a 3A switch mode power supply and is capable of driving up to 48

micro servos directly from the PCB. All of the processors 70 I/O pins are terminated as

both a female header and a servo compatible 3pin male header.

Features:

• ATmega1280 16MHz CPU

• 128K FLASH, 8K SRAM and 4K EEPROM

• USB interface and ISP socket

• Built in 3A switch mode power supply (7V – 30V input)

• 70 I/O pins with male and female headers

• Support for up to 48 servos

• 16x 10bit analog inputs

• 15x 8bit PWM outputs

• 1x I2C

• 6x External interrupt pins

• 4x Serial communication

• Comes with Arduino boot-loader installed

Programming the Spider controller: The Spider controller has been designed to be 100% compatible with the Arduino Mega and comes with the Arduino boot loader installed. The boot loader allows programs written in the Arduino IDE to be uploaded via the USB interface. More information about Arduino can be found here: http://arduino.cc/en/Guide/Introduction This manual assumes use of Arduino 0022 or later, which can be downloaded from here: http://arduino.cc/en/Main/Software.

Analog pins: Pins A0 to A15 are by default analog inputs. Each analog input has 10bit resolution and can measure the voltage on its pin. Input voltage should not exceed the analog reference voltage (default value is +5V). The input voltage is measured using the analogRead() command. The reference voltage is Vcc(+5V) by default. The reference voltage can be changed using the analogReference() command.

Using servos: All 70 I/O pins have a servo compatible 3 pin male header. The pin closest to the outer edge of the PCB is ground, the center pin is +5V and the inner most pin is the signal. This pin arrangement is also useful for powering sensors. Most miniature and standard servos require between 4.8V and 6V and will work happily directly from the PCB. High-powered servos requiring 6V or more should be powered via an external power source or directly from the battery.
