Rabbit’s new BL4S100 single-board computers offer a cost-competitive solution for control and communication that dramatically reduces your time to market. The series is designed to support the rapidly-increasing use of ZigBee connectivity for companies looking to deploy wireless networking. Digi International’s ZigBee RF modules are compatible with ZigBee PRO compliant devices from other manufacturers, providing great flexibility in choices of nodes to include in the network. Build feature-rich web pages that allow control and monitoring of ZigBee enabled networks by using ZigBee AT and API command libraries.

With two available RS-232 ports, eight analog inputs and 20 Digital I/O lines, the BL4S100 is well suited to handle a wide range of applications requiring ZigBee connectivity. The optional plastic enclosure and mesh networking add-on kit support further design requirements.

The BL4S100 is a low-cost Rabbit® 4000 microprocessor based single-board computer series that delivers ZigBee and Ethernet capability. On-board ZigBee RF modules offer mesh networking functionality to make networking easy to deploy and simple to maintain. With both Ethernet and ZigBee connectivity integrated onto the BL4S100, the series delivers a low-cost platform to design a ZigBee enabled Ethernet network.

The Rabbit RIO® Advantage

The BL4S100 series uses our Rabbit RIO chip to add a powerful I/O subsystem. The on-board Rabbit RIO device adds software configurable counter/timer blocks that can perform a variety of useful I/O capability, including event capture/counting, quadrature decoding, PWM and PPM generation, and edge or level based interrupts. This subsystem capability delivered by the Rabbit RIO device frees the microprocessor for control, data processing and communications tasks. Each BL4S100 board has 8 counter/timer blocks available in the I/O subsystem.

  • Monitoring and control for intelligent building automation
  • Asset tracking and management for commercial and industrial applications
  • Air quality monitoring
  • Energy monitoring and management

Rabbit’s BL4S100 single-board computers offer a low-cost solution for control and communication that gets you through the development process quickly. The BL4S100 series is designed to support the rapidly increasing use of ZigBee connectivity for companies looking to deploy wireless networking. Digi’s XBee® ZB ZigBee PRO RF modules are compatible with other manufacturers’ devices using the ZigBee PRO compliant feature set, providing great flexibility in choices of nodes to include on the network.

The BL4S100 series integrates on-board functionality to support a wide range of applications. Analog inputs, general purpose I/O as well as serial ports, along with 10Base-T Ethernet connectivity provide design resources for both commercial and industrial applications.

Develop and debug programs using Rabbit’s industry-proven Dynamic C integrated development environment. The Dynamic C IDE includes the popular µC/OS-II Real-time Kernel operating system, point-to-point protocol (PPP), FAT file system, RabbitWeb, and other select libraries.

Connect the BL4S100 series board to the PC using a USB cable and then debug using breakpoints, watch expressions and other features oriented toward real-time embedded systems programming. An extensive library of drivers and sample programs is provided, including a royalty-free TCP/IP stack for network and Internet communications. Rabbit provides full source code for most of the library routines.
