Adafruit Feather form factor has become more popular in recent years with third-parties introducing Feather compatible boards such as the Giant Board (Linux capable), OrangeCrab (FPGA), or FeatherS2 (ESP32 WiFi + Bluetooth), and as well as FeatherWing add-on boards. Azerbaijan based MakerTronika Labs has launched their own Feather compatible board with LoRa connectivity: Penguino Feather 4260. The development board is powered by a RAK4260 module based on SAMR34 LoRa SiP and supports both 868 and 915 MHz bands. Penguino Feather 4260 specifications: LoRa module – Rak wireless RAK4260 module with: SiP – Microchip ATSAMR34J18 SiP with SAML21 Arm Cortex M0+ MCU @ 48 MHz, 40 KB RAM, 256 KB Flash, Semtech SX1276 LoRa Connectivity Frequency Range – 862 to 1020 MHz High level of accuracy and stability (32MHz TXCO) Max Tx Power: 20dBm; Max Sensitivity: -148dBm; Rx Current: 17mA (typical) Compliant with LoRaWan 1.0.2 Power Consumption Low RX current of 13.6mA 790 nA in sleep mode Antenna – SMA and […]
Rakwireless has launched several IoT evaluation boards such as RAK4260 LoRaWAN EVB relying on WisBlock modules comprised of a carrier board and a module. So far, those were always sold as part of evaluation boards, but now the company is trying to expand WisBlock use as a modular system, so users can easily build their custom systems, LEGO style. The modular system is based on four different block types: WisBlock Base – A carrier board with connectors for other block types, power supply, some ports WisBlock Core – Module with a microcontroller/processor WisBlock Sensor – Modules with environmental sensors, motion sensors, ambient light sensors, or others WisBlock IO – Adds more inputs, outputs, or connectivity options including LTE-M / NB-IoT, cellular and Wi-Fi modules, NFC reader, and interfaces for I2C, UART, ADC, and GPIO. The company is just getting started with the solution, and initially will be offering one WisBlock baseboard, an improved version of the one used with RAK4260 […]
Last year with covered Dragino RS485-LN RS485 to LoRaWAN converter that extends the range of RS485 wirelessly up to 15+km thanks to LoRaWAN connectivity. Rakwireless has now launched a similar product with RAK7431 Modbus RS485 to LoRaWAN bridge. RAK7431 key features and specifications: MCU- STM32L071 industrial-grade MCU with low-power consumption (4uA sleep) LoRa Semtech SX1272 LoRa transceiver Frequencies – RU864, IN865, EU868, US915, AU915, KR920, AS923 Tx Power – 20dBm (Max) LoRaWAN 1.0.3 protocol stack, supports Class A, Class B & C Polling mode, transparent mode and packet mode RS485 6-pin RS485 terminal block Support up to 16x RS485 devices, with up to 32 instruction sets Baud rate – Configurable 9600 to 115200bps Can power RS485 devices via a dedicated output USB – 1x Micro USB configuration port Misc – Reset key, 3x LEDs Input Voltages – 8-48V DC input via 2-pin terminal block; 5V via Micro USB Dimensions – 93.6 x 100.3 x 24mm Protection Grade – IP31 (Protected […]
RAK Wireless launched its first Mini PCIe LoRaWAN concentrator module in 2018 with RAK833 mPCIe card featuring Semtech SX1301 LoRa baseband chip. It was soon followed by RAK2247 mPCIe with a very similar design but some tweaks to increase its maximum transmission power and range, and improve thermals and stability with the addition of a heatsink. The company has now introduced a new version with RAK2287 Mini PCie LoRaWAN concentrator module being mostly inspired by RAK2247 module but replacing Semtech SX1301 by Semtech SX1302 LoRa transceiver that’s suppose to reduce current consumption (and heat), lower the BoM cost, and able to handle a higher amount of traffic. The new mini PCIe card also adds u-blox ZOE-M8Q GPS system-in-package to provide GNSS functionality. RAK2287 key features and specifications: LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-end Tx power – up to 27dBm Rx sensitivity – down to -139dBm @ SF12, BW 125 kHz LoRaWAN® 1.0.2 compatible. LoRa band coverage […]
Outdoor LoRaWAN gateways meant to be deployed in the field usually cost several hundred dollars, so companies also offer cheaper gateways for indoor use that can be used by developers. RAKWireless offers this type of gateway with products such as Pilot Gateway Pro RAK7243 based on Raspberry Pi 3 Model B+ board, or RAK7244 LoRaWAN Developer Gateway featuring the more recent Raspberry Pi 4 board and sold for $212 and up with price depending on options such as cellular connectivity. The company has now worked on providing much cheaper indoor/developer gateways with their RAK7246 and RAK7246G LoRAWAN developer gateways with the latter adding GPS. RAK7246 is available. RAK7246 key features and specifications: SBC – Raspberry Pi Zero W board with Broadcom BCM2835 ARM11 processor @ 1GHz, 512MB RAM Storage – 16GB MicroSD card Connectivity 802.11 b/g/n WiFi and Bluetooth 4.0 via Cypress CYW43438 module found on RPi Zero W board RAK2246 Pi HAT LoRaWAN concentrator module: SX1308 baseband processor Full […]
After launching RAK831 Lite LoRaWAN gateway based on Raspberry Pi 3 board in 2018, RAK Wireless introduced Pilot Gateway Pro RAK7243 gateway with the more recent Raspberry Pi 3B+ SBC earlier this year. But with the launch of Raspberry Pi 4 last June, the Raspberry Pi 3B+ has become much harder to procure, so RAK has now launched an updated LoRa gateway featuring Raspberry Pi 4 SBC together with the company’s RAK2245 Pi Hat Edition LoRaWAN gateway concentrator module. RAK7244 LoRaWAN Developer Gateway specifications: SBC – Raspberry Pi 4 Model B with 2GB RAM Connectivity LoRa RAK2245 Pi Hat LoRaWAN gateway concentrator module with 1x SX1301 baseband processor, 2x SX125x Tx/Rx front-ends LoRaWAN v1.0.2 support Support for 8 channels and spreading factors SF7 to SF12 Bands – 433MHz, 470MHz, 865MHz, 868MHz, 915MHz, 920MHz, 923MHz Tx Power: 27 dBm Max RX Sensitivity: -139dBm Cellular – Optional 4G LTE support via RAK2013 Cellular Pi HAT (Quectel EG95 LTE CAT4 module) GNSS – […]
We just had another of our yearly “Giveaway week” on CNX Software with 7 prizes including Arm and RISC-V development boards, NB-IoT tracker, USB-C hub, as well as development kits based on ESP32 or ESP8266 WiSoCs. People just had to comment within a 48 hours period, and we would randomly select a winner each day. We now have all confirmed winners with a strong start from Europe, Asia catching up mid-week, before with Poland and Brazil taking the week-end prizes: Balena Fin Developer Kit – Laurent H, FRANCE WisCellular NB-IoT & eMTC GPS Tracker – Jimmy, SWEDEN MINIX NEO S1 USB-C Hub with 120GB built-in SSD – Jeroen, BELGIUM Maixduino Sipeed M1 RISC-V AI Kit – Nguyen Tung, VIETNAM ANAVI Gas Detector Starter Kit – Bumsik Kim, SOUTH KOREA Particle Mesh IoT Development Kit – Wojciech Lubicz-Lapinski, POLAND NanoPi M4V2 SBC & Metal Case Kit – Thiago Tavares, BRAZIL I checked the results for 2018 and 2017 for fun, and […]
Rak Wireless WisCellular is an NB-IoT & eMTC Arduino shield based on Quectel BG96 module with 2G fallback that is similar to the company’s previous-generation WisLTE board, except it is certified for the global markets. I received a beta sample last year and went through the instructions to use it with a Hologram SIM card, but sadly I never managed to make it work, and eventually learned the Hologram SIM card did not support NB-IoT in Thailand. So I would have had to buy a local SIM card, but at the time, they didn’t sell those, and the only way to get an NB-IoT SIM card was to buy a development kit. Before going ahead with the purchase, I asked about coverage in my area but never managed to get a definitive answer so I gave up. So instead of keeping it in a drawer at home, I’d better just give it to somebody else who should make better use […]
