The DC5V 2 Channels Relay Module is similar to the 4-channel version but with two relay channels. It is suitable for projects requiring the control of two separate high-power devices, providing a reliable interface between microcontrollers.
The CD4027BM is a single monolithic chip integrated circuit containing two identical complementary-symmetry J-K master-slave flip-flops. Each flip-flop has provisions for individual J, K, Set, Reset, and Clock input signals.
The 2N5401 TO-92 Bipolar Transistors PNP 160V 600mA. 2N5400 and 2N5401 are silicon PNP transistors designed for high voltage amplifier applications, TO-92 Bipolar Transistors PNP 160V 600mA.
