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. […]

STMicroelectronics Introduces Affordable LoRa Development Packs For All User Types

STMicroelectronics has recently announced the launch of a new set of LoRa Development packs, which are not only affordable, but they are aiming to a large pool of users from big organizations, small companies, hackers, engineers, students, and hobbyists. The ready-to-use development packs are aimed for applications bent on leveraging LoRa ’s long-range, low-power wireless IoT connectivity for tracking, positioning, metering, and many related applications. STMicroelectronics is releasing the P-NUCLEO-LRWAN2 pack and P-NUCLEO-LRWAN3 pack. Both packs provide a complete LoRaWAN development kit, and they include gateways, end-nodes, and ST tools, which are all based on the STM32 Nucleo evaluation boards. The LoRa gateway on both packs is based on the STM32 Nucleo-144 development board, NUCLEO-F746ZG. The STM32 Nucleo-144 development board with STM32F746ZG MCU supports Arduino, ST Zio, and Morpho connectivity. The Gateway header pins are exposed out to facilitate more development, and they support interfacing with LoRaWAN network-server providers LORIOT, Actility, myDevices Cayenne for LoRa […]

LoDev S76S Board Combines STM32, LoRa and Arm Mbed Support (Crowdfunding)

There are already plenty of low power boards with a LoRa radio, but Ronoth offers another option with their tiny LoDev S76S LoRa development board featuring AcSip S76S SiP (system-in-package) with STMicro STM32L073 microcontroller, a Semtech SX1276 LoRa radio, and other components. While most hobbyist LoRa boards are designed to be programmed with the Arduino IDE, LoDev S76S is instead compatible with Arm Mbed. LoDev S76S board specifications: SiP – AcSip S76S system-in-package with STMicro STM32L073 Arm Cortex-M0+ microcontroller @ 48 MHz with 192 kB flash, 20 kB RAM Semtech SX1276 chip supporting global 863MHz ~ 928MHz ISM Bands RF front-end LoRa Connectivity Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +20 dBm Range – up to 15 km coverage in suburban areas and up to 5 km coverage in urban areas SMA antenna connector USB – 1x micro USB port for programming and power […]

Semtech SX1261/SX1262 LoRa Development Kit Now Available for $305

Semtech announced SX1261, SX1262 and SX1268 LoRa chips in January as updates to their current LoRa solutions with a lower footprint, better efficiency, and even longer range. Mass production and development kits were expected in March 2018, and today I found out Semtech SX1261/SX1262 development kit is sold on Mouser for $305. The SX126xDVK1CAS kit comes with the following items: 2x SX126xMB1xAS RF modules including an  ST Nucleo Mbed board and a touchscreen 2x Mini-USB / USB connection cables 2x 868/915MHz antennas 2x Mini-USB cables 2x touchscreen styluses Read-Me Note The SX1261/SX1262 LoRa Transceivers offer continuous frequency coverage from 150MHz to 960MHz. You’ll find information to get started in the user guide. Basically, the two boards will show a menu on the touchscreen with radio test modes, settings and utilities (e.g. firmware update) as well as two demos: DEMO Ping Pong performs a bidirectional range test between the two radio […]

STMicro VL53L1X Time of Flight (ToF) Sensor Extends Distance Measurement Range up to 4 Meters

STMicroElectronics VL53L0X ToF (Time-of-flight) range sensor is a tiny chip that can accurately and quickly measure distance up to 2 meters using laser light.  I had the chance to test the sensor via TinyLIDAR board connected Arduino and Raspberry Pi, and found it was a great little sensor. TinyLIDAR includes an STM32 MCU, but you can also find standalone board for as low as about $4 shipped on Aliexpress. However, if 2 meters is too short a range for your project, the good news is that STMicro has now launched VL53L1X ToF “FlightSense” sensor with a range of up to 4 meters. VL53L1X is pin-to-pin compatible with VL53L0X, so existing PCBs could be re-used with the new sensor. STMicro VL53L1X main specifications: Emitter: 940 nm invisible laser (Class1) SPAD (single photon avalanche diode) receiving array with integrated lens Low-power microcontroller running advanced digital firmware Distance Ranging up to 4 meters […]
