MatchCore

Both models can be programmed using Dialog DA1468X SDK, a community has been setup, as well as a developer’s blog, but so far I’ve been pretty quite, as the company works on completing development. There’s very little info about MatchModule , which will be a 25x25mm LoRa module that can be integrated into your own project. The only info I’ve got about is in the table below.

The MatchBox gateway should sell for around $299, while MatchStick and MatchCore should go for $28 and $16 respectively, I assume in their minimal configuration, as final price will depend on the choice of sensors.

You may be able to find some more details on Matchx.io website.

EEMBC IoT-Connect is a Family of Benchmarks Designed To Test the Power Efficiency of IoT Devices

April 14th, 2017 No comments

EEMBC, the Embedded Microprocessor Benchmark Consortium, has been providing benchmarks for embedded systems since 1996, including ULPBench helping to rank micro-controllers by their power efficiency. But with the Internet of Things gaining traction, it’s important to test more than just the MCU core’s power efficiency, and having a benchmark taking sensors and connectivity into account would be useful.

That’s exactly what EEMC IoT-Connect benchmark family aims for with the three main characteristics:

  • Provides flexibility to accommodate various communication protocols (e.g. Bluetooth, Thread, LoRa, WiFi)
  • Portable to work with any vendor’s microcontroller and radio-module products
  • Compatible with EEMBC ULPBench and EEMBC IoT-Secure benchmarks

The first benchmark of the family is IoTMark-BLE connectivity profile that supports Bluetooth (LE) MCUs. The benchmark requires fixed payload size, frequency of transmission, and transmit power, and performs a complete sequence of event ranging from sensor reading, to BLE notifications, and command write and CRC.

The IoT-Connect test infrastructure is completed, and supports IoTMark-BLE, but to access it, you’ll either need to license one or more benchmark suites, join the EEMBC Board of Directors, or an application-focused EEMBC subcommittee. There are also special licenses for faculty members colleges and universities.

The next IoT-Connect benchmark profile will be completed around Q4 2017 for another communication protocol which is yet to be decided between Wifi, Thread, and LoRA.

You can find more details on EEMBC’s IoT Connect product page.

Most development board come with SDK using older version of Linux, but LicheePi Zero supports the latest Linux 4.10 kernel, as well as buildroot, Debian, and Raspbian Jessie with Pixel (experimental). The source code and hardware documentation can be found on Github.

Another selling point of this tiny board is the number of add-boards, with a WiFi board that be either plugged into the micro SDcard slot, or soldered along some of the 2.54mm pitch header, several converter using the RGB interface for VGA, LVDS, HDMI, DVP camera) or even some extra GPIOs.

The developer also provides a baseboard for LicheePi Zero module giving access to a 3.5mm audio jack, a built-in microphone, and Ethernet, as well as I/O ports for even more add-ons such as cameras, OLED or TFT displays, speakers, LoRa modules, and so on.

The modularity and options of Lichee Pi Zero is well summarized in the diagram below.

To get started easier, the developers also worked on some projects or bundles like a portable Linux handheld computer, a mini DIY laptop, VGA or HDMI computer bundles, “LoRa Netgate”, wireless speakers, etc… You can watch the demo of some of those, and more details about the board and modules in the video below.

While LicheePi Zero and ZeroW models are respectively $6 and $8 per unit, you can’t buy one only at price, as the minimum order is two, so $12 for Zero, and $16 for ZeroW, except for the developer edition (shipped ASAP) that’s $12 for one ZeroW. ZeroW mini laptop DIY suit rewards with a LicheePi Zero, a micro SD wifi card, an OTG adapter, a 5″ 800×480 LCD, a wireless keyboard, a LiPo battery, and other accessories as shown at the start of the video above is just $39, while the LoRa Netgate suite with 2 A.I Thinker LoRa modules and a custom protocol (not LoRaWAN) goes for $40. There are many other rewards that you can checked in the Indiegogo page. Shipping is not included by only adds $5, and delivery is planned for May to June 2017 depending on perks. You can ask your question on on Indiegogo, as well as iLichee Forums.

433/868/915 MHz LoRa Modules Are Now Selling for $6 and Up

December 29th, 2016 5 comments

Market forecasts for the Internet of Things promise billions of connected device in the years to come, but this won’t happen when LPWAN  connector sensors cost $50 or more, so prices will have to come down. I’ve been told that one company is working on a WiFi + LoRa module that’s going to sell for $5 to $6 sometimes in 2017, but in the meantime, it’s possible to get some LoRa modules for less than $10, albeit limited to 433 MHz frequency not the more common 868 MHz (EU) and 915 MHz (US), thanks to products such as AI-Thinker Ra-02 module.

ai-thinker-ra-02-lora-moduleRa-02 specifications:

  • Chipset – Semtech SX1278 low power long range transceiver
  • Radio
    • 433MHz frequency (420 to 450 MHz range)
    • +20dBm – 10mW constant RF output vs. V supply; up to 300 kbps bitrate
    • Supports FSK, GFSK, MSK, GMSK, LoRa and OOK Modulation Mode
    • 127dB RSSI wave range.
  • I/Os – 16x half through holes with half-duplex SPI communication, GPIO and power signals; 2.0 mm pitch
  • Supply Voltage – 1.8 – 3.7V, default 3.3V
  • Power Consumption – Receive < 10.8mA (LnaBoost closed, Band 1); transmist: < 120mA(+20dBm), sleep: 0.2 uA
  • Dimensions – Estimated 16×16 mm
  • Certifications – FCC/CE
  • Temperature Range – -40 to +85 °C

I could only find the module on a company called Smart Prototyping selling the module for $9 plus shipping ($6.84), which amounts to roughly $15. But you could also get your hands on a pair of two SX1278 modules and spring antennas for $14.85 including shipping on Aliexpress, or about $7 per module.

cheap-lora-moduleThe specifications of this cheaper module are basically the same as the AI-Thinker module. The seller is also promising to send the schematics and program by e-mail. If you look for DRF1278F on the web, you’ll find other websites selling it, for example it can be found on eBay for as low as $5.60 with one antenna and including shipping.

[Update: for 868MHz search for DRF1272F ($8.28), and 868/915 MHz for DRF1276G ($8.68)]
