			*) SD card support is easy to provide to AVR/Arduino platforms, offering virtually unlimited storage capacity.
			*) RN171 (WiFi) should be moved to software serial port, completely freeing the hardware UART for external peripherials.
			*) An ATmega2560, rather than ATMega32U4, would offer enough flash space to include telnet-style networked CLI functionality alongside existing requirements.

	Router based occupancy sensor is on the way out. Lack of a crystal oscillator does not guarantee operation internal communication with the microcontroller when significantly beyond room temperature.		Router based occupancy sensor is on the way out.

	Wired network configuration is set to DHCP, wireless configuration can be set by connecting a computer to the LAN interface. Microcontroller communication can be verified by watching the TX/RX LEDs, which should blink every minute or so. Detected occupancy sensor status is reported through onboard LED labeled "OCC".
