SMT Caddy is powered by a Raspberry Pi™ (model 3) computer module. Raspberry Pi-3 is a complete computer system with a quad-core ARM Cortex-based processor, running at 1.2 GHz, with 1.0 GB of RAM, built-in LCD driver, HDMI connector for external monitor, µSD card for storage (up to 32 GB), multiple USB ports, LAN port, and built-in wireless network and Bluetooth adapters.

A high speed (80x), 16 GB µSD card is installed, preloaded with the operating system, supporting libraries, SMT Caddy application and documentation, reserving ample space for future software upgrades, additions and features.

Raspbian, an open source Linux based environment has been installed as the SMT Caddy’s operating system.

A 7” multi-touch LCD screen is utilized for displaying the graphics. The screen is directly interfaced to SMT Caddy’s LCD & Touch Driver, leaving the HDMI port available for a larger external monitor, if desired. The 7” LCD monitor resolution is 800x480, producing better than 130 DPI for very fine graphics. If an external monitor is opted, a Standard 1080P unit is recommended. Video will be streamed at 30 frames per second on a 1080P monitor. In either configuration, the end-result is live video, with virtually undetectable latency or flicker!

Future software versions will be always free and upgrades are performed over the internet.
