of Pins 3 Mounting Type Surface Mount

5mm Material Used

These are Carbon Film Resistor with a value of 620 ohm 1/4W and tolerance of ±5%

the CH341 provides a conventional USB printer port that combines USB-relevant protocol with the Windows operating system to easily upgrade a standard parallel printer to the USB bus

It can quickly measure the USB port's output voltage as well as the device's operational current or load voltage

74HC85 4-Bit Comparator IC (7485 IC) DIP-16 Package Buzzer and speakers of Pins 3 Mounting Type74HC series ICs are High speed logic gates with very low power consumption that utilize advanced silicon gate CMOS technology and 74HC85 is one of them. 74HC85 ICs contain a 4 bit Comparator that can compare two binary, BCD, or other monotonic codes and present the three possible magnitude results at the output i. e. A>B, A=B, and A<B. And its weighted inputs are A[0: 3] and B[0: 3] where A3 and B3 are MSB. 74HC85 comparator can work in both series
