Coming Soon! JumpStart IoT is a set of ready-to-use software components that lets you connect embedded systems to the Internet.

JumpStart IoT core components are:

  • The REXIS multitasking kernel. Simple to use with a minimal learning curve.
    • Low memory and runtime overhead.
    • Tasks are just C functions (running a forever loop).
    • Priority-based preemptive scheduling: it just works out of the box without requiring complicated configuration.
    • Includes Messaging, MUTEX and semaphores, and tasking API.
    • Interrupt handler safe API.
  • lwIP TCP/IP stack. Industry standard TCP/IP stack with both low-level and high-level (e.g.: sockets) API. Support for DHCP, IPv4, and IPv6. Fully integrated with REXIS.
  • mbedTLS library. TLS 1.2 compatible security layer.
  • MQTT, NTP, etc. application layers.
  • Forthcoming: AWS and other Cloud service integration examples.

Benefits To The Users

  • REXIS+lwIP can save you months of development time, giving you the features, performance and robustness that get your products out to market faster.
  • lwIP is one of the most widely used open source TCP/IP stacks used in many commercial applications. It is in active development since early 2000s with a healthy user and developer community.
  • REXIS and other non-Open Source components available as binary and source for Cortex-M3, M4, and M7 MCUs (Cortex-M0 support forthcoming).
  • Easy to port to different MCUs. SysTick timer is the only timer used. One only needs to port the Ethernet hardware interface to use it.
  • Minimal impact on interrupt performance.
  • Inexpensive non-royalty based licensing fee.


  • NC - $99: binary release for REXIS and other non-Open Source components. Non-commercial use only. Includes one hour of consulting.
  • STD - $999: source and binary releases for REXIS and other non-Open Source components. Includes 3 hours of consulting. License to use on one product.
  • PRO - $9999: same as STD, with license to use on unlimited number of products from one company.
