The STN 128×64 display with RA8808 controller and COG technology provides high readability and easy integration with systems based on the KS0108A. Support for the SPI interface and extended temperature range allow its use in mobile, industrial, and outdoor devices.

This set of two quadrature encoders for 20D extended-shaft motors provides precise rotational speed monitoring with 20 pulses per motor revolution. The devices utilize magnetic disc and Hall-effect sensors operating from 2.7-18V, and the digital outputs can be connected directly to a microcontroller. The encoders mount directly to the back of the motor, and the compact design and 6-pin JST PH connectors facilitate integration into robotic projects and control systems. Pololu 5661
