Description: This shield is a 8 channel interface for external encoders . It keeps track of the pulses that are sent from encoders.
It offloads all the computation of keeping track of the encoders to the chip. The interface between the shield and the Arduino board is SPI .
It includes example code that can read all 8 channels.
It is based on the LS7366R chip .
Crystal is at 27 MHz and the encoder chips could read at maximum freq/4 = 6.75 MHz
The encoder connector provides 5V out.
It is using only 4 Arduino pins + the SPI port pins . The Digital pins can be disconnected using 3 jumpers.
