64 Mbit Pseudo-SRAM with SPI/QPI interface, auto refresh, burst linear and wrap modes, and configurable I/O interface (1-/4-bit) in SOP-8 package. High performance and low power consumption ideal for data caching in embedded systems and IoT devices

A reflective sensor that precisely measures the intensity of light reflected from a surface using an IR LED and a phototransistor. It offers a long detection range—optimally around 20 mm, and up to 80 mm—thanks to the QTRXL sensor with a built-in lens and adjustable LED brightness. It generates a digital RC signal that\'s easily read by microcontrollers like Arduino or Raspberry Pi. Pololu 4540
