Semtech launches LLCC68 LoRa Transceiver for Smart Home Applications

Semtech, a leader in LoRa and RF technology, is continuing its support for the LoRa ecosystem with the launch of a LoRa Smart Home transceiver called the LLCC68. The device is designed for deploying existing and new LPWAN technologies for smart homes, community, and consumer applications. The LoRa Smart Home (LLCC68) is like every other sub-GHz LoRa RF transceiver but mostly targeted to indoor and medium outdoor applications. The device is hardware compatible with the SX126x series like the: SX1261, SX1262, and SX1268. The LLCC68 transceiver is optimized for battery-powered applications with multi-year life expectancy. It consumes as little as 600nA of sleep current, 4.6 mA of active receive current and can transmit at +22 dBm thanks to highly efficient integrated power amplifiers. According to SemTech, The new LoRa® Smart Home device offers a unique opportunity to accelerate the consumer adoption of smart home connected solutions. As an end-to-end solution, […]

VCON Adds IoT Cloud Connectivity to Existing STM32 & AVR Products

mdash iot cloud

You can have a product based on a microcontroller and operating fully offline, for example, a washing machine. But you’d now like to update your appliance to connect to the cloud so it can upload data to the cloud, and help your customer access it. This is a non-trivial update as it requires you to add a communication module be it WiFi or Ethernet, or a new microcontroller that would require you to update your firmware to support networking and other new features. You’d also need to develop your own cloud platform, and potentially a smartphone app. Cesanta VCON platform aims to simplify the upgrade with firmware that can be flashed to ESP8266 or ESP32 module, and remotely upgrade the firmware on STM32 and AVR microcontrollers. On the hardware side, you’d need to wire your existing MCU to the ESP32 module with UART for data, BOOT/RESET for OTA firmware update. […]

NComputing RX420(HDX) Raspberry Pi 4 Thin Client Works with Citrix HDX

RX-420 HDX Raspberry Pi 4 Thin Client

NComputing RX300 Raspberry Pi 3 thin client was launched in 2017 with support for the company’ vSpace Pro desktop virtualization solution for Linux and Windows, and I tested it accessing a Windows Server 2006 host located in Singapore, and performance was pretty good for a remote system as I could play 1080p YouTube videos, browse multiple tabs in Chrome, etc.. relatively smoothly.  This type of solution is aimed at businesses, for which it may be easier and cheaper to handle a fleet of devices using thin clients and servers, instead of traditional PC’s. Beside its vSpace Pro RX300 thin client, NComputing also introduced another Raspberry Pi 3 thin client that same year with RX-HDX using a design similar to RX300 but instead integrating support for Citrix HDX virtualization technology. NComputing now unveiled an update for the latter with RX420(HDX) thin client based on Raspberry Pi 4 SBC with 2GB RAM. […]

STMicro STM32WL is the World’s First LoRa SoC

There is no denying that the Internet of Things is going to disrupt a lot of markets and it’s already happening to some extent. The question being asked is: “What IoT connectivity technology will lead this disruption era?”. One major technology in this connectivity race is LoRa. LoRa’s long-range, low-power, small footprint, simplicity, and the amazing community backing it, have allowed it to find its way into various applications while gaining for the top LPWAN IoT connectivity technology. STMicroelectronics, one of the biggest semiconductor manufacturer, also believes in the potential of LoRa with the launch of STM32WL, making it the World’s first die-integrated LoRa System-on-Chip. Traditional LoRa embedded platforms usually involve the need for a separate MCU chip and different LoRa transceiver chips either coupled together in one single package or separately. This undoubtedly adds extra design complexity, size, and even cost. STMicro hopes to address this with their STM32WL SoC. […]
