The ROM-WT138LM(N) series are remote control receiver modules. Pin diode and receiver IC are assembled on one module. Small- sized, light-weight, and low current consumption. modules have been achieved by using resin mold. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses.
Features - Supply Voltage Range: 2.7V to 6 V - TTL and CMOS compatibility - Photo detector and preamplifier in one package. - Internal filter for PCM frequency - Open collector output (built-in Pull-up resistor(40 ㏀ )) - Output active low - Enhanced Immunity against all kinds of disturbance light - No occurrence of disturbance pulses at output pin within nominal conditions. - Short settling time after power On.( below 1msec)
The ODROID-C1+ is esteemed to be the most powerful low-cost single board computer available, as well as being an extremely versatile device. Featuring a quad-core Amlogic processor, advanced Mali GPU, and Gigabit Ethernet, it can function as a home theater set-top box, a general purpose computer for web browsing, gaming and socializing
CM108AH is a highly integrated single chip USB audio solution. All essential analog modules are embedded in CM108AH, including dual DAC and headphone amplifier, ADC, microphone booster, PLL, regulator, and USB transceiver.
Uninterrupted Power Supply is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. The on-battery runtime of most uninterruptible power sources is relatively short but sufficient to start a standby power source or properly shut down the ODROID.
