2. GENERAL
The MotoPi board is an expansion board for the control and use of up to
16 PWM controlled servomotors.
The board can be supplied additionally by 4.8
-
6 V so that the ideal
supply of the motors is always ensured and even greater projects can be
supplied by enough power.
It is for example perfectly suited for the control of the Joy
-
IT robot arm.
Article number: Robot02
The robot arm made of aluminium gets its
movement from 6 separately controllable 20 kg
motors. It is mounted on a based rotary plate
(360°). The base plate is made out of 4.5 mm
thick acryl and has mounting holes for all
common singleboard
-
computer and
microcontollers.
3. TECHNICAL DATA & SAFETY INSTRUCTIONS
The MotoPi board is equipped with 16 channels for 5V servomotors as
well as a possibility for connecting an additional capacitor.
Moreover, the board has 4 analog, 2 digital and a I2C connection facility.
The power supply is ensured by a 5 V coaxial power connector or via a
power supply between 4.8 and 6 V.
It is also additionally equipped with a quartz oscillator to keep
frequencies as precisely as possible and deviations as small as possible.
