KEYBOARD PCB
MAINBOARD PCB
Keyboard PCB Considerations
• The keyboard keys need to be placed in a layout similar to a standard keyboard
• Trace sizes minimized because of compactness of layout, and placed far from cutouts to avoid damage when cutting slots for keys on PCB
• Size of vias/drill holes minimized
Microcontroller Considerations
• Placed at a central location to minimize trace lengths
• Small resistors placed in series with microcontroller programmer lines to provide protection from ESD
• No analog signals, just digital control and communication signals
• Decoupling capacitors placed as close as possible to VDD and GND pins
Power Supply Considerations• Power supply components placed as close
together as possible and separate from digital control/communication components/traces
• Ground traces between voltage sources and voltage regulators as short as possible to minimize common impedance
• Keyboard connector carries power to Keyboard PCB, so placed close to power supply components
• Bypass capacitors placed as close to regulators as possible
