We designed a simple electronic circuit that contains a: relay (5V 2A Finder 30.22.9.005.0010), diode (IN5817), a resistor of 6.3K and a transistor (547BC). We attach the schematic below. The PCB has to be about 40x50 mm.
The aim of this circuit is to cut off the alimentation of a 12V line depending on a 3.3 line, with a delay of 60s controlled by an arduino.
We need the following files:
·Gerberx2 files for the copper layers, soldermask and legend layers, mechanical layer and SMD paste layers. Plus carbon, peel-off and via-fill layers as needed.
·Excellon drill file(s) for drilling.
Thank you in advance
