39 Euros FiPy Board Supports Sigfox, LoRa, LTE Cat M1/NB1, Bluetooth 4.2, and WiFi (Crowdfunding)

Long range LPWAN solutions have just started to hit the market, and there are so many standards such as Sigfox and LoRa that it’s difficult to know who will eventually be the winner, or if different standards will co-exist over the long term, and in a general sense it might not be so easy to decide which one is best suited to your project without experimenting first. Pycom has a solution to this problem, as they’ve made a board similar to LoPy with WiFi, Bluetooth, and LoRa, but instead included 5 long and short range IoT protocols: Sigfox, LoRa, LTE Cat M1 & Cat NB1, Bluetooth, and WiFi. Pycom FiPy board specifications: SoC – Espressif ESP32 dual core Tensilica L108 processors @ up to 160 MHz with BT 4.2 and WiFi System Memory – 4MB RAM Storage – 8MB flash memory Connectivity WiFi 802.11 b/g/n @ 16 Mbps up to […]

A Closer Look at Ingenu RPMA Alternative to LoRa or Sigfox LPWAN Standards & RPMA Development Kit

I’ve recently started to write a bit more about long range LPWAN standards for IoT applications, especially LoRa and Sigfox, as commercial networks are being launched, and relatively low cost hardware platforms are being introduced to the market. There are also other highly expected standards such as Weightless and LTE Cat M that will bring more competition to the market. Ingenu RPMA (Random Phase Multiple Access) is another available standard that’s been in deployment for a while, and based on an earlier comparison of  long range LPWAN standards, it comes with long range, supports up to 384,000 nodes per “sector”, operates in the unlicensed 2.4 GHz ISM band, and offers high combined uplink and downlink bandwidth than competitors. Ingenu recently contacted me and provided some more details and information about their technology and development kit. One of the documents includes an “independent analysis completed by ABI Research, Inc.” comparing features […]

GR-LoRa is a Reverse-Engineered Open Source Implementation of LoRa PHY

LPWAN standards such as LoRa or Sigfox allow you to transmit data over long distance, at ultra low power (up to 10 years on a AA battery), and for free if your use your own network (P2P or gateway), or a few dollars per years if you go through a network provider. The low cost is possible since those standards rely on 900 MHz ISM bands, meaning nobody has to pay millions of dollars to the government to obtain a license fee. Matt Knight looked at LoRa, and while Level 2 and 3 of the protocol (LoRaWan) has public documentation, Level 1 (LoRa PHY) is proprietary and the standard is proprietary. So he decided to reverse-engineer LoRa PHY using Microchip RN2903 based LoRa Technology Mote and Ettus B210 USB software defined radio, and software packages and tools such as Python and GNU Radio to successfully deliver GR-LoRa open source “GNU Radio […]

Marvin is a Plug and Play, Arduino Compatible, LoRa USB IoT Development Board (Crowdfunding)

LoRa appears to be one of the most popular LPWAN standards so far, with hobbyist development boards such as LoPy or LoRaONE, and we’ll soon have at least one more choice thanks to Marvin, a LoRa development board with a full size USB port. Marvin board specifications: MCU – Atmel/Microchip ATmega32u AVR MCU (same as Arduino Leonardo board) Connectivity – LoRa via Microchip RN2483; Supports both 868 MHz and 433 MHz frequency bands, on-board antenna USB – 1x USB, 1x micro USB port for power and programming Debugging – USB, and ISP header Expansion – 5x Grove connectors Power Supply – 5V via USB port Dimensions – N/A, but similar to USB flash drive The board can be programmed with the Arduino IDE, and they mention IBM Bluemix platform, and Node-RED, but overall details about documentation and software are scarce right now. One of the advantage of this form factor is […]

Dragino LoRa/GPS HAT Board for Raspberry Pi Sells for $32

There are several ways to play with LoRaWAN protocol on the Raspberry Pi including RisingHF Discovery kit or Cooking Hacks LoRa Shield for Raspberry Pi, but the latter requires you to spend close to $100 just for the shield, the complete Lora discovery kit costs close to $400. Dragino Tech LoRa/GPS HAT board should be a more cost effective way to get started with LoRa on Raspberry Pi, as it sells for $32 + shipping on Tindie. Dragino LoRa/GPS HAT specifications: Connectivity LoRa Semtech SX1276/SX1278 transceiver @ 433/868, or 915 MHz (Country dependent, pre-configured in the factory) 168 dB maximum link budget. +20 dBm – 100 mW constant RF output vs. +14 dBm high efficiency PA.

RisingHF IoT Discovery is a LoRaWAN Evaluation Kit for Raspberry Pi

There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF. Among the products offered by the company, there’s a potentially interesting development kit called RisingHF IoT Discovery with the following components: 1x Raspberry Pi board 1x RHF0M301 LoRa Gateway based on Semtech SX1301 1x RHF4T002  adapter for Raspberry Pi and RHF0M301 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz 3x RHF76-052 […]
