6 Digi Embedded Solutions

7 What is an Embedded System? Small device that can be embedded into another device or enclosure Often does not have a direct user interaction Low power consumption Usually has a low cost Combine common HW components such as: Microprocessor Memory (SDRAM and Flash) I/O peripherals (UART, USB, GPIO, etc.) Pre-integrated software support Development Kit with Software Tools Add-on Application Kits Page 7

8 Why it is different from a Box? It needs more things than a box does: design a carrier/support board stabilized power supply connectors, level shifters, etc. might need an enclosure But it is better because: has a much lower cost more suitable for very high volume (1K- 30K) easier to customize/expand Page 8

9 Value Proposition Fast design integration ready-made solution for rapid deployment Ease-of-use standard environment, tools and OS Future-safe design & Investment protection future growth with continuous enhancements Industrial and Medical solution long term availability (5-10+ years) Complete Solution including Hardware, Software, tools, support, design reviews, custom services (SW and HW) Partners and Distributors Local partners help speeding up development and support Page 9

10 Key Applications Security / Surveillance and Market Focus Example Application Medical / Healthcare Fitness / Wellness Renewable Energy Utilities Transportation Agriculture / Irrigation Security Surveillance Page 10

11 A Full Family The Digi Connect family includes several high performance embedded modules such as: Connect ME-9210 Connect WiME-9210 ConnectCard Wi-i.MX28 ConnectCore Wi-i.MX51 ConnectCore Wi-i.MX53 The Digi modules share HW peripherals, SW libraries and support common Operating Systems for easier development and future compatibility Page 11

49 BusyBox Once Digi DEL has booted fully, the BusyBox will show up BusyBox combines tiny versions of many common Linux utilities into a single small executable The commands included are rebuilt specifically for small and embedded system (size and resources optimized) It is also modular so users can easily include or exclude commands (or features) It is basically a Bourne shell on a diet!!! NOTE: Our pre-built binary has IPv6 support DISABLED Customers wanting to use IPv6 on busybox need to enable and rebuild busybox Page 49
