Chip (SOIC8) Module B7 for 6 leds

SOIC-8 microchip with DC-Car encapsulation.

The B7 module performs 2 consecutive and identical sequences, each of them alternates three quadruple flashes.

The B5 module is similar but the 2 sequences are simultaneous.

The operating voltage is between 3'6 and 5 volts, each output supports 20 mA. The resistance values of each LED are between 330 ohms and 470 ohms, depending on the desired brightness.

The anodes (positive poles) of all LEDs are connected between each other and also connected to the output + of the DC-Car decoder voltage transformer, or any other alternative power supply.

Control of the module operation is done by feeding it directly with any light output without series resistance of the DC-Car decoder (in this example flash light 4 programmed as continuous output), or directly by a negative signal, so this module can also be installed in vehicles without digital decoder.

PIN 1: Sequence 1 led 1
PIN 2: Sequence 1 led 2
PIN 3: Sequence 1 led 3
PIN 4: Negative (feed)
PIN 5: Sequence 2 led 1
PIN 6: Sequence 2 led 2
PIN 7: Sequence 2 led 3
PIN 8: Positive (3'5 / 5 V DC)
