K1001 - 8 Channel Serial Servo Controller, Assembled & Tested
K1001 is an 8-Channel Serial Servo Controller based on the Atmel 89C2051 microcontroller. It accepts RS232 or TTL serial data from a computer or microcontroller and outputs PWM (pulse width modulated) signals to control up to eight RC servo motors (as used in radio-controlled model airplanes, cars, etc.).
Unused servo pins can be reconfigured for digital output to drive on/off devices.
Up to four controllers can be multi-dropped on a single serial port for controlling up to 32 servo motors - more on request.
