Installation Guidelines

PCB Design Considerations

// Standard footprint specifications:
// Dual row: 0.1" x 0.1" grid
// Hole diameter: 1.0mm (0.040")
// Pad diameter: 1.8mm (0.070")
// Row spacing: 2.54mm (0.1")
// Via size: 0.020" for routing
 
// Design considerations:
// - Provide adequate clearance around headers
// - Consider mating connector height
// - Plan for cable routing and strain relief
// - Mark pin 1 clearly on silkscreen
// - Use standard library footprints
