0-50V 4A DC Power Supply Class D Power Amplifier Interference Suppression Board E-891 Low voltage DC (0V~50V) Terminal description: Vin: input positive terminal Vin-: input negative terminal Vout-: output negative terminal

hese displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display. This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

This is a 12V 1-Channel Relay interface board which can be controlled directly by a wide range of micro controllers such as Arduino, AVR, PIC, ARM, 8051 and so on. It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc High quality screw terminals (Terminal Block) provided (C, NC , NO) for quick and easy connection LED Status indicators to indicate the relay ON/OFF status.
