This is an optical bio-metric fingerprint reader/sensor (R305) module with TTL UART interface for direct connections to a microcontroller UART. The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person. This module can directly interface with any 3.3V or 5V microcontrollers, but a suitable level converter/serial adapter is required for interfacing with the serial port of a PC. -
RAC20-15DK Switched power supply 20W ±15V RAC-15 PCB mounted AC/DC switched power supply. The module can be supplied with a voltage between 85-264VAC or 120-370VDC and will convert it to two stabilized DC voltages. Maximum output power is 20W. The output is protected against short-circuit, overload and over voltage. Please observe that the module is powered with mains voltage Input voltage: 85 - 264VAC / 120 - 370VDC Output voltage: -15VDC / +15VDC Output current: 670mA / 670mA Maximum power: 20W Dimensions: 52.5 x 27.4 x 23mm Manufacturer: Recom Part.no: RAC20-15DK
