Fully Assembled Circuit Board - Alternating Led Fade Flash Unit

Fully assembled, professionally soldered, fully tested.

Board has two ports that will flash two leds alternatively with a fading effect (neither led will shut down completely, but will fade sufficiently in turn to give a realistic alternating effect, similar to lights seen at a railway level crossing).

Flash speed is approximately twice per second.

5v to 9v DC battery input.

Connection terminals are micro screw terminal connectors for each led port, and a standard screw terminal connectors for the 9v battery clip input.

As the board is a transistor unit, both leds must be connected before the battery power is applied in order for them to flash.

Overall board dimensions (L x W x H): 30mm x 28mm x 14mm
