Semtech SX1302 LoRa Transceiver to Deliver Cheaper, More Efficient Gateways

After our interview with Rak Wireless CEO, we received a comment inquiring about the availability of SX1302 gateways. Semtech so far had two LoRa transceivers for gateways namely SX1301 and SX1308, but I had never heard about a third one. Semtech SX1302 is brand new, the latest generation of baseband LoRa chip for gateways that is said to reduce current consumption in order to simplify the thermal design of gateways, as well as the BoM (bill of materials) costs), while being capable of handling a higher amount of traffic. Semtech SX1302 LoRa Transceiver Key features: Up to -141 dBm sensitivity with SX1250 Tx/Rx front-end 125 kHz LoRa reception with: 8 x 8 channels LoRa packet detectors 8 x SF5-SF12 LoRa demodulators 8 x SF5-SF10 LoRa demodulators 125 /250 / 500 kHz LoRa demodulator (G)FSK demodulator Direct interface to Semtech transceivers SX1255, SX1257 and SX1250 SPI host interface Single 32 MHz […]

Dragino LHT65 is a $30 LoRaWAN Temperature & Humidity Sensor

LHT65 LoRaWAN Temperature & Humidity Sensor

If you’d like to monitor temperature and/or humidity in remote locations, one way is to get a LoRaWAN gateway, and setup a few LoRaWAN nodes connected to your own temperature & humidity sensors, and add a battery and enclosure. But if you’d like to save some time, and get a turnkey solution, Dragino LHT65 LoRaWAN temperature & humidity sensor may be an option. The sensor comes with an internal SHT20 sensor, and as well as an external DS18B20 waterproof temperature sensor.

LPWAN Market Update – An Interview with RAK Wireless CEO

CNX Software interviews Ken Yu, RAK Wireless’ founder & CEO, to learn more about the company and the current & future state of the LPWAN (Low Power WAN) market especially with regards to NB-IoT and LoRaWAN. CNXSoft: We’ve already covered several products from RAK Wireless on CNX Software, starting with WiFi IoT boards several years ago, and more recently LPWAN products based on NB-IoT or LoRa. But for readers who may not be familiar with RAK Wireless yet, could you provide a short description of what the company does? Ken Yu: RAKwireless was founded in 2014. The core founder team consists of professionals coming from established leaders in the Networking industry as Qualcomm, H3C, etc. Because our engineers have more than 10 years of experience designing Wi-Fi solutions, this was the core of our business in the beginning. RAKwireless is working towards a vision of a connected world and In […]

Olimex Launches NB-IoT DevKit Based on Quectel BC66 Module for 19 Euros

There are three LPWAN standards currently dominating the space LoRaWAN, NB-IoT, and Sigfox. In a recent presentation, Olimex explains NB-IoT (aka LTE Cat NB1) offers several advantages over LoRaWAN and Sigfox which include: Higher speeds of up to 25.5 kbps (UL/DL) Single GSM base station can handle up to 100 000 NB-IoT nodes Single GSM base station can cover up to 10-100km range in rural environments, and 1 to 10km in urban settings Lasts up to 10 years on a Lithium 3V battery if less than 200 bytes are sent per day The main disadvantage they listed was operator dependence, as you rely on the operator for coverage, and anything related to connectivity. In Bulgaria in particular, they found out it was not easy to get an NB-IoT SIM card activated, and the operator may shut you off without notice. For reference here in Thailand, last time I checked I […]

Arduino MKR WAN 1310 LoRa Board Gets HW Security, Longer Battery Life and a 2MB SPI flash

Two year ago Arduino launched MKR WAN 1300 board powered by Arduino Zero compatible Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU and a Murata CMWZ1ZZABZ LoRa module based on Semtech SX1276 and STMicro STM32L microcontroller. The company has now announced a new improved LoRa board – MKR WAN 1310 – with lower power consumption thanks to a new battery charger , a 2MB SPI flash which enables data logging and other OTA (Over-the-Air) functions, and a crypto chip that can securely store credentials and certificates. Specifications: MCU – Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash (8KB for bootloader) External Storage – 2MB SPI flash Digital I/O Pins – 8x digital I/Os, 12x PWM, UART, SPI, and I2C, 8x external interrupts Analog Pins – 7x analog inputs (8/10/12-bit ADC), and 1x analog output (10-bit DAC) DC Current per I/O […]

RAKWireless Introduces RAK7200 LoRa Tracker | Features & Specifications

RAK7200 is a LoRa Tracker node built around the AcSIP S76G chip. It integrates the ultra-low-power STM32L073 micro-controller, the SX1276 LoRa long range modem, and the CXD5603GF GPS receiver. The RAK7200, being a fully functioning LoRaWAN device, is particularly suited for IoT applications. Such as asset tracking, smart vehicle management, location-based service, etc. According to the device manufacturers, RAKWireless, a leading Chinese IoT solutions company, based in Shenzhen, RAK7200 requires minimal setup. Just pop in the included battery, close the housing and you can start sensing your GPS data over LoRaWAN. Furthermore, there are sensors built-into the board: a 9-axis accelerometer and pressure sensor. The new GPS Tracker node is an upgrade over the company’s earlier offering in the GPS tracker space, the RAK7205. Now, the earlier version, the RAK7205, was mostly aimed at developers, with its larger more robust casing and solar panel. But the RA7200 is more of […]

N-Fuse Launches Raspberry Pi 3B+ LoRaWAN Gateway with PoE Support

PoE enabled Raspberry Pi 3B+ based LoRaWAN™ Gateway

Raspberry Pi is everywhere, and this small size single-board computer has reshaped technology and STEM education. The launch of the recent Raspberry Pi 4 is evident in the success and continuous growth. The Raspberry Pi 3B+ has seen so much success in several maker’s projects, while not the most powerful SBC in the market, but undoubtedly one of the most popular. I once put together an AI-powered mobile robot using just a Raspberry Pi 3B+, an RPLidar A2, and Raspberry Camera which was way capable of so many things. Another exciting Raspberry Pi end product is the “PoE enabled Raspberry Pi 3B+ based LoRaWAN Gateway” from n-fuse. The PoE enabled Raspberry Pi 3B+ based LoRaWAN Gateway as called by n-fuse is a LoRaWAN gateway based on the Raspberry Pi 3B+, the LRWCCx-MPCIE Concentrator, and the SBCPoE RPI Hat. It supports both the Europe 868Mhz and America 915Mhz frequency (you have […]
