Microchip based Orange LoRa Explorer Kit Connects to Orange’s own LoRaWAN Network

You’d think Telecom operators with all infrastructure in place would focus their IoT efforts on LTE Cat M1 or LTE Cat NB-IoT, but Orange has setup its own LoRa network in France with the aim of achieving national coverage by December 2017, at which time they’ll also test interconnection and roaming with other European operators. The company has also launched the LoRa Explorer Kit based on Microchip solutions, and designed by SODAQ. Orange LoRa Explorer Kit specifications: MCU – Microchip Atmel SAMD21 ARM Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB RAM, up to 16KB EEPROM by emulation Storage – 4Mbit serial flash (Microchip SST25PF040C) Connectivity Microchip RN2483A LoRa module + PCB antenna Microchip RN4871 Bluetooth 4.2 module (BLE) with ceramic antenna Security – Microchip ATECC508A1 crypto chip to securely store LoRa keys. USB – 1x micro USB port for charging and programming Expansion – “Arduino M0” compatible headers with 10-bit […]

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted. That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon. The company has recently announced their Track 100 family […]

Whitecat ESP32 N1 Board Combines ESP32 WiFi + Bluetooth SoC with a LoRa Transceiver, Runs Lua RTOS

Espressif ESP32 SoC is gaining traction right now as prices have come down, and there’s still an on-going fight among LPWAN standards with LoRaWAN being fairly popular in Europe. Whitecat, a group of engineers from several companies based in Citilab, Barcelona, Spain, has designed a board that combines both ESP32 and a LoRA transceiver, bringing an alternative to Pycom LoPy board, but instead of running MicroPython, they have developed Lua-RTOS. Whitecat ESP32 N1 hardware specifications: SoC – Espressif ESP32 dual-core Tensilica LX6 microprocessor @ up to 240MHz with 520kB internal SRAM Storage – 4MB flash memory Connectivity LoRa WAN transceiver working in the 868 (EU) MHz / 915 (USA) MHz with on-board antenna, and u.FL connector for external antenna Integrated 802.11b/g/n WiFi transceiver with on-board antenna, and u.FL connector for external antenna Integrated dual-mode Bluetooth (classic and BLE) I/O Headers – 2x 16-pin with SPI, I2C, I2S, SDIO, UART, CAN, […]

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

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 […]
