868 MHz Wireless Data ModuleFebruary 17
, 2015 — Linx Technologies, a Merlin, OR based developer and manufacturer of Internet of Things (IoT) Products and Solutions, is pleased to introduce its new 868MHz wireless data modules for the European Market. The HumPRO™ Series transceiver is built on the popular Hummingbird platform, and is designed for the reliable transfer of digital data.The 868MHz version uses Listen Before Talk (LBT) and Adaptive Frequency Agility (AFA) to meet ETSI regulations that allow a transmitter duty cycle of 64%. The module manages all timing requirements to ensure ETSI compliance.

The new HumPRO™ 868MHz version outputs up to 10dBm. This results in a line-of-sight range of up to 1600 m.

Increased Duty Cycle with Listen Before Talk and Adaptive Frequency Agility

The wireless data modules employ a fast-locking approach with Listen Before Talk (LBT) and Adaptive Frequency Agility (AFA) system for noise immunity and higher transmitter duty cycle as allowed by ETSI regulations. Fast-locking also allows the modules to wake up, send data, and go to sleep quickly, making it an excellent solution for battery powered applications. The HumPRO™ 868MHz wireless data modules meet all of the ETSI requirements for LBT + AFA, allowing a max duty cycle of 64%. The modules handle all transmitter timing required by the regulations.


The HumPRO™ Series supports 128-bit AES encryption as an option. It also provides a unique join process that makes setting up a network in the field as simple as a few button presses.
All modules have a unique 32-bit serial number that can be used as an address. Additional address modes support customer-assigned 16 or 32-bit source and destination addressing. The addressing methods support point-to-point and broadcast links. Address masking by the receiving module allows for creating subnets. More advanced network methods can also be implemented with an external microcontroller.

Low Cost RF Data Modules

868MHz Wireless Data ModulesThe HumPRO™ Series module is a completely integrated RF transceiver and processor designed to transmit digital data across a wireless link. It uses advanced System on Chip (SoC) technology to minimize the footprint and the number of components.


Along with low cost being a key design feature, the Hummingbird Series modules were designed for ease of use. Focusing on a core Linx value, the HumPRO™ Series wireless data module is designed for simplicity, compared to other designs that add unnecessary features, complexity and cost to their design. Housed in a compact reflow-compatible SMD package, the transceiver requires no external RF components except an antenna, which greatly simplifies integration and lowers assembly costs.

A standard UART interface is used to configure the module for operation and for the data input and output. This is suitable for direct connection to UARTs on many microcontrollers, USB converters and RS-232 converters. A simple command set is used for configuration and control. Modules can be pre-configured for fixed point-to-point or broadcast topologies allowing streaming data (no commands) during operation. The HumPRO™ Series RF transceiver module offers a number of features that make it suitable for many data transfer applications.

By building on the Hummingbird platform and focusing on low cost with agility, Linx Technologies has been able to create a high performance, cost effective module in 868MHz. With LBT + AFA, this 868MHz RF module is both simple and powerful, making it easier for people to develop their products for the Internet of Things. – Kris Lafko, VP of Marketing & Sales at Linx Technologies


The HumPRO™ Series modules can be used to create many types of wireless networks. By design, the modules do not provide network routing since the internal memory size of the module would limit the overall network size. Having the network routing outside of the RF module dramatically increases the level of nodes within your network without the worry of module limitations.

Best in Class Master Development System

To aid rapid development, the HumPRO™ Series low cost RF modules are available as part of a newly conceived type of Master Development System. This comprehensive development kit is designed to assist in the rapid evaluation and integration of the HumPRO™ Series data transceiver modules. The all-inclusive system features several pre-assembled evaluation boards, which include everything needed to quickly test the operation of the transceiver modules.
