Serial Servo Controller ( Usart & SPI) with ADC

Description of product

Description 
The "Serial Servo Controller (USART & SPI) with ADC" from Rhydolabz is a very compact solution for controlling up to eight RC servos from a PC or microcontroller. Each servo speed and range can be controlled independently. This servo controller supports USART and SPI communications. The user could control the servomotors by sending the desired command  from a SPI  or USART supporting device. Servo Controller supports two communication protocols  Mini SSCII and RHYDO-SSC protocol. The built in 2 ADC Port can be used for measuring any analog voltage (ie. 2 Sensor values) and the other ADC channel is permanently connected to measure Servo Voltage. With appropriate command from host controller the module will do ADC conversion for the selected channel and send out the result via USART/SPI. This feature is extremely useful for microcontroller without Onchip ADC ( like AT89S52), and to detect the battery low condition. Up to 128 Servos can be controlled by connecting 16 Module in Parallel.
