A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge (SMT components only)
and 7 timer channels (capable of PWM)
This powerful synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 7
1 kHz sample rate (CD quality) audio to your projects with Teensy 3
Optimal range: 5 mm
QTR-HD-11A Reflectance Sensor Array: 11-Channel, 4mm Pitch, Analog Output hub-zubehoer A-Star 32U4 Robot Controller LVThis array of IR LED phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage and separate controls for the odd and even emitters. In general, the closer the object, the higher the contrast between light and dark readings, but high reflectance objects are generally detectable out to around 40 mm. This
