Project Overview

• 5 separate PCBs (4 module boxes and 1 control board)

• Each PCB has different requirements based on function.

• All Communicate wirelessly

Commercial Products

•X10–Powerline Communication–Simple–Unsightly–Wall Wart–No Status Indication or manualcontrol.–Inexpensive ($20)

Commercial Products

•Lutron RadioRA–Proprietary Wireless protocol–Integrated in Wall Box(Not easiest retrofitting)–Expensive ($95)–Fun Colors–Manual Operation and Status

Commercial Products

•Roku–Simple–Fanless–Status Light–Compact

Packaging Specifications

Packaging Specifications

•HID:–3” x 3” PCB–USB Interface

Packaging Specifications

•IR:–3” x 3” PCB–DC Wall Wart Power

Packaging Specifications

•Shade:–4” x 6” PCB–Room for 2 relays–Terminal Block Connectors

Packaging Specifications

Packaging Specifications

•Control:–3” x 3” PCB–Serial Interface–Motherboard in offthe shelf mini-ITX case

PCB Footprints

•Wireless:–Try to separate from power circuitry to reduce noise–Avoid Metal Enclosures

•Size:– Some large components like transformer, SSR–Leave enough room for headers and routing
