A320 PCB for MCDU (v 1)

Control for the following inputs:

• every tactile switch on the MCDU

and outputs:

• two leds per annunciator

You can use standard 6x6 mm tactile switches or the ones with led included (the circuit is ready for those type of switches). In the second case each button would be backlit by the switch. If you choose the optional components, the switches with leds will be included.

Needed components (optional). This kit includes everything (except the MCDU panel) to build the panel, so you don't need to add any component when ordering the MCDU panel:

• 72 6x6 mm tactile switch with warm white led
• 2 40-pins IDC connector for PCB (male + female)
• 2 20-pins IDC connectors for PCB (male + female)
• 3 2-pin polarized connectors (male + female)
• 6 high bright white leds
• 6 high bright amber led
• 1 high bright green led
• 6 100 ohms resistors
• 7 470 ohms resistor
• 14 M3x10 bolts
• 2 M3x15 bolts
• 6 M3x20 bolts
• 15 plastic washers 3 mm
• 4 10 mm spacers female-female
• 26 M3 nuts
• 12 grover washers M3
