this regulator can deliver up to 1 A continuous when the input voltage is higher than the output voltage (stepping down)

QTR-8A Reflectance Sensor Array Category_Motor & Servo Controllers/Servo Controllers Jumpers are included on theThis sensor module has 8 IR LED phototransistor pairs mounted on a 0. 375" pitch, making it a great detector for a line following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power savings options. Each sensor provides a separate analog voltage output. Note: The QTR 8A reflectance sensor array requires analog inputs to take readings. The similar QTR
