Ai-Thinker Ra-08 LoRaWAN module features ASR6601 chip (Sponsored)

Ai-Thinker Ra-08/08H are new LoRaWAN modules based on ASR Microelectronics ASR6601 module featuring a 48MHz ARM Cortex M4 microcontroller and Semtech SX1262 transceiver allowing long-range, low power communication for the Internet of Things. Both LoRaWAN modules share most of the same specifications, but the Ra-08 module operates in the 410-525MHz frequency band, while the Ra-08H module works in the widely used 803MHz to 930MHz band. Ai-Thinker also provides a development kit for each module. Ai-Thinker Ra-08/Rs-08H key features and specifications: Programmable embedded Arm Cortex-M4 MCU with 128 KB of Flash and 16 KB of SRAM LoRa radio Sensitivity – -138 dBm @ SF12/125KHz Tx power – Up to +22dBm Frequencies Ra-08 – 410 MHz to 525 MHz Ra-07H – 803 MHz to 930 MHz Spread spectrum factor – SF5, SF6, SF7, SF8, SF9, SF10, SF11, SF12 LoRa, (G)FSK, BPSK, and (G)MSK modulation Bit rate up to 62.5 Kbps in LoRa […]

Dragino LDS02 LoRaWAN door and window sensor offers long range and battery life

Dragino LDS02 LoRaWAN door & window sensor

Home automation usually relies on short-range wireless standards such as Bluetooth LE, Zigbee, or WiFi, sometimes with the help of repeaters for larger houses. But if you need to monitor large houses, several houses on a piece of land, or apartments, you’d be glad that you can also do so, at least for doors and windows, with LoRaWAN using Dragino LDS02 sensor. The LDS02 sensor will work like your typical wireless door/window sensor, detection when those are opened and closed, and for how long, but will offer a much longer range of up to 2km in urban settings, as well as battery life meaning it could last for years depending on the frequency of door/window events, as well as uplink frequency configuration. Dragino LDS02 LoRaWAN door sensor specifications: Based on SX1262 LoRa transceiver LoRaWAN v1.0.3 Class A Bands – CN470, EU433, KR920, US915, EU868, AS923, AU915, IN865 Door Open/Close detection […]

Challenger RP2040 LoRa board combines Raspberry Pi RP2040 MCU with RFM95W LoRa module

Invector Labs is now offering a variant of the WiFi-based Challenger RP2040 board with a LoRa radio. The Challenger RP2040 LoRa board features the Hope RF RFM95W LoRa radio transceiver module instead of the ESP8285 WiFi chip found in the original board. Raspberry Pi RP2040 has already been used in combination with a LoRa module, notably in Rakwireless RAK11300 WisDuo LPWAN module and the “LoRa Expansion for Pico“, a baseboard for Raspberry Pi Pico equipped with a LoRa module, but it’s the first time I see the combination in a development board form factor, which as a potential bonus following Adafruit Feather form factor. Challenger RP2040 LoRa board preliminary specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Wireless module – Hope RF RFM95W connected via SPI channel and some GPIOs 168 dB maximum link budget. +20 dBm – 100 mW […]

RAKwireless introduces 16 new WisBlock modules with LoRaWAN, NFC reader, etc…

Wisblock LoRaWAN & NFC Reader wireless modules

RAKwireless will add new modules to its WisBlock IoT modular system every quarter. Last July, WisBlock family welcomed 14 new modules, and in September 2021, RAK11310 Raspberry Pi RP2040 LoRaWAN core was introduced together with a new baseboard and various sensor modules. This time around, the company launched 16 new Wisblock modules with two wireless modules, one adding LoRaWAN to an ESP32 core module, the other acting as an RFID and NFC card reader, as well as six sensor modules, and eight “interface” modules ranging from barcode scanners to keypads. WisBlock Wireless modules RAK13300 WisBlock LPWAN module based on Semtech SX1262 transceiver extends the communication abilities of the RAK11200 ESP32 WiFi & Bluetooth LE module with LoRa / LoRaWAN. RAK13600 WisBlock NFC Reader enables reading and writing of NFC tags like RFID cards and other NFC enabled devices using NXP PN532 chip. WisBlock Sensor modules RAK12013 WisBlock Radar Sensor – […]

Year 2021 in review – Top 10 posts and statistics

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]
