AAEON UPC-GWS01 is Tiny IoT Gateway Powered by UP Core Board

AAEON’s UP Core is an affordable and compact Intel Atom x5-Z8350 based board that was launched last year on Kickstarter for 69 Euros and up. The company has now integrated the board into at least one of their product with UPC-GWS01, a tiny IoT gateway with WiFi and Bluetooth connectivity, as well as support for optional 3G/4G LTE connectivity via a mini PCIe slot. A carrier board for UP Core also added Ethernet and a DB9 serial port to the setup. AAEON UPC-GWS01 specifications: SoC – Intel Atom x5-Z8350 quad core Cherry Trail processor with Intel HD 400 graphics System Memory – 1GB/ 2GB/ 4GB onboard DDR3L-1600 Storage – 16GB/32GB/64GB eMMC Video and Audio Output – 1x HDMI port Connectivity Gigabit Ethernet via Realtek 8111G WIFI 802.11 b/g/n @ 2.4 GHz (WiFi 4) and Bluetooth 4.0 Optional 3G/4G cellular connectivity via mPCIe socket USB – 1x USB 3.0 host port […]

Air602 is another $2 WiFi IoT Module, Based on Winner Micro W600 Arm SoC

WiFi used to be fairly expensive to add to MCU projects with spending $30 to $40 just for a WiFi module pretty common just less than 5 years ago, but this all changed thanks to Tensilica based Espressif ESP8266 modules selling for $5 in 2014, and an active community gathering behind the WiSoC, and related modules and development board. ESP8266 modules are now available for under $2, and around two years ago it looked like we would have another option based on Arm Cortex-M3 with RTL8710 modules such as Pine64’s PADI IoT stamp also selling for about $2 in single quantities. However, most people did not really the benefit of switching to another platform based on Arm for this type of applications, and the products never really took off, many went away, and PADI IoT stamp appears to be one of the few survivors. Yet another $2 WiFi IoT module […]

WisCellular Certified Global LTE IoT Arduino Shield Enters Beta Testing

RAK Wireless introduced WisLTE Arduino shield last year based on Quectel BG96 module with support for NB-IoT (Cat NB1), eMTC (Cat M1), and 2G fallback as well as GPS location. WisLTE worked globally, but the company did not go through the certification process, at least not for the global market, meaning the shield could not be used in commercial applications. That’s why Rak Wireless has been working on WisCellular shield, also based on Quectel BG96, but this time with global certification. WisCellular specifications: Cellular Module – Quectel BG96 (based on Qualcomm MDM9206) Cellular Network 2G/GSM (GPRS/EPGRS) 4G/LTE-M (Cat M1) NB-IoT (Cat NB1) Global Bands EDGE/EGPRS: 850/900/1800/1900MHz LTE FDD: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B26/B28 LTE TDD: B39 (For Cat M1 Only) Data Rate Cat M1: Max. 300Kbps (DL), Max. 375Kbps (UL) Cat NB1: Max. 32Kbps (DL), Max. 70Kbps (UL) EDGE: Max. 296Kbps (DL), Max. 236.8Kbps (UL) GPRS: Max. 107Kbps (DL), Max. 85.6Kbps (UL) Voice – […]

How to Make a Cheap Single Channel Gateway with an ESP32 LoRa Board

Actual LoRaWAN gateways based on Semtech SX1301 concentrator can be pretty expensive, and even if you take a LoRa gateway design based on Raspberry Pi for indoor placement or experimentation, price is still around $200. A much cheaper way (~$70) is to use a single channel LoRa gateway, which as the name implies only support one channel, which limits the number of nodes, and forces you to set the nodes at the same frequency as your gateway. Those are not really suitable for commercial offerings, but if you manage your own gateway and nodes that should be usable. If you only plan to implement a network with a dozen nodes or so, you could even use much cheap ESP32 LoRa board like the ESP32 LoRa 1-Channel Gateway sold on Sparkfun for $29.95. Hardware specifications: Connectivity WiFi and Bluetooth 4.2 LE via ESP32-WROOM-32 module with integrated PCB antenna LoRa @ 868 […]

Embedded Linux Conference Europe & OpenIoT Summit Europe 2018 Schedule

Embedded Linux Conference OpenIOT Summit Europe 2018

The Embedded Linux Conference & OpenIoT Summit 2018 took place in March of this year in the US, but the European version of the events are now planned to take place on October 21-24 in Edinburg, UK, and the schedule has already been released. So let’s make a virtual schedule to find out more about some of interesting subjects that are covered at the conferences. The conference and summit really only officially start on Monday 22, but there are a few talks on Sunday afternoon too. Sunday, October 21 13:30 – 15:15 – Tutorial: Introduction to Quantum Computing Using Qiskit – Ali Javadi-Abhari, IBM Qiskit is a comprehensive open-source tool for quantum computation. From simple demonstrations of quantum mechanical effects to complicated algorithms for solving problems in AI and chemistry, Qiskit allows users to build and run programs on quantum computers of today. Qiskit is built with modularity and extensibility […]

$50 Fish32 Seed “Education” ESP32 Board Comes with Plenty of I/Os, Sensors, and Connectivity Options

Sometimes I feel the word “Education” is sometimes thrown around for marketing purpose, and AnalogLamb Fish32 Seed board for “ESP32 Community Education Board” feels that way to me as so far, I could not see any tutorials or other teaching/ learning resources for the board. Having said that I can see why it could be potentially used for education: the sheer number of features, sensors, and connectivity options should allow students to learn to program my different components around ESP32. It’s just at this stage it may not be such an easy platform to learn on. Fish32 Seed board specifications: Supported ESP32 Modules – ESP32-WROVER, ALB32-WROVER, ESP32-WROOM-32 Connectivity 802.11 b/g/n WiFi and Bluetooth 4.2 via ESP32 10/100M Ethernet (RJ45) via WIZnet W5500 chip with support for up to 8 independent sockets LoRa via SX1278 chip (433 MHz) Sensors NXP MPU-9250 with 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer […]

Dragino LoRaST M.2 LoRa Card Convert Compatible Platforms into LoRa Nodes

Modern motherboards or single board computers often expose mPCIe or M.2 / NGFF socket, and we’ve seen it was possible to easily add a LoRa radio using RAK833 mPCIe LoRaWAN gateway card to hardware with an mPCIe (USB/SPI) socket. You can now do something similar with Dragino LoRaST M.2 LoRa card by inserting into a spare M.2 / NGFF socket. There’s an important distinction however, as while RAK833 is designed for LoRa gateways, LoRaST is based on SX1276/SX1278 for LoRa end nodes. Dragino LoRaST M.2 LoRa card specifications: MCU – STMicro STM32L072CZT6 Arm Cortex M0+ MCU @ 32 MHz with 192 KB flash, 20 KB of RAM, 6 KB data EEPROM LoRa Connectivity Semtech SX1276/78 LoRa Wireless Modem Available Bands – 433/868/915/920 Mhz Built-in antenna or optional external antenna via I-PEX connector Host interface – Standard M.2 (NGFF) interface Supply Voltage – 1.8V ~ 3.6V Dimensions – 22 x 42 […]
