The RF Solutions high-performance ZETA module was recently updated to include a simple SPI and UART interface. The ZETAPLUS module doesn’t require external components, which means a fast and effective plug-and-play setup.
Available on 433-, 868-, and 915-MHz frequencies, the module is easy to set up and you’ll be sending and receiving data quickly. Furthermore, you’ll find it easy to create networks of ZETAPLUS modules or point-to-point links without the need for time-consuming register configuration.
With an impressive 2-km range, the ZETAPLUS is well-suited for sensor networks, sleepy nodes, and numerous other telemetry, control, and Internet of Things (IoT) applications.
NXP Semiconductors recently added the OL2385 family sub-GHz wireless transceivers to its low-power microcontroller and 2.4 GHz portfolio for Internet of Things (IoT) applications. Based on a PIN-to-PIN compatible, sub-GHz transceiver hardware platform, the OL2385 supports multiple wireless protocols (e.g., Sigfox, W-MBus powered by Xemex, and ZigBee IEEE 802.15.4).
With a two-way RF channel and common modulation schemes for networking applicatios, the OL2385 transceivers cover a wide range of frequency bands from 160 to 960 MHz. In addition, extended range radio operation is enabled with high sensitivity up to –128 dBm. Operation in congested environments is enhanced with 60 dB at 1 MHz of blocking performance and 60 dB of image rejection.
Platform features include: 14-dBm Tx output power compliant with ETSI limits; typical 29-mA transmit power consumption at full output power; less than 11 mA receive power consumption; excellent phase noise of –127 dBc at 1 MHz in the 868- and 915-MHz band for flexibility with external power amplifiers; and Japanese ARIB T108 standard compliant.
The OL2385 platform samples and development boards with SIGFOX are currently available. Mass production of preprogrammed parts are scheduled for the end of Q4 2017.
The LEMOS-LMX-WiFi is a compact wireless transceiver that can operate on IEEE 802.11 networks. It is supported by a 32-bit microcontroller running a scalable TCP/IP stack. The transceiver is well suited for wireless embedded applications involving digital remote control, digital and analog remote monitoring, asset tracking, security systems, point of sale terminals, sensor monitoring, machine-to-machine (M2M) communication, environmental monitoring and control.
The 40.64-mm × 73.66-mm transceiver is available in two models: integrated PCB antenna or external antenna. Its features include software-selectable analog and digital I/O pins, a 2-Mbps maximum data rate, and a unique IEEE MAC address.
The LEMOS-LMX-WiFi can be powered by any 3.3-V to – 6-VDC source that can deliver 200 mA of current. The transceiver can interface to external devices that communicate via USART, I2C, and SPI. It also supports infrastructure and ad hoc networks.
