Wio LTE GPS Tracker Board Comes with a 4G Modem, Supports Espruino Firmware (JavaScript Programming)

Seeed Studio launched Wio GPS tracker with a 2G GSM module a few months ago, and while it should work in some countries, others are phasing out 2G networks, and only support 3G or 4G. The company has now launched an update with Wio LTE board with the same form factor, and most of the same features except they replaced the 2G/Bluetooth/GNSS module with a 4G LTE/GNSS module, and Atmel SAMD21 ARM Cortex M0+ microcontroller by an STMicro STM32 ARM Cortex-M4F MCU. Wio LTE board specifications: MCU – STMicro STM32F405RG ARM Cortex M4F MCU @ 168 MHz with 1MB flash, 192+4KB SRAM Storage – micro SD slot Connectivity via Quectel EC21-A (America) module LTE Cat.1 modem: FDD LTE: B2/B4/B12 WCDMA: B2/B4/B5 AT Command: 3GPP TS27.007 and enhanced AT Commands Data – LTE-FDD Max 10Mbps(DL) Max 5Mbps (UL) NanoSIM card 2x u.FL antenna connectors GNSS – GPS/BeiDou/GLONASS/Galileo/QZSS with 1x u.FL GNSS […]

RadioShuttle Network Protocol is an Efficient, Fast & Secure Alternative to LoRaWAN Protocol

LoRaWAN protocol is one of the most popular LPWAN standards used for the Internet of Things today, but some people found it “lacked efficiency, did not support direct node-to-node communication, and was too costly and far too complicated for many applications”, so they developed their own LoRa wireless protocol software called RadioShuttle, which they claim is “capable of efficiently sending messages in a fast and secure way between simple LoRa modules”. Some of the key features of the protocol include: Support for secure or insecure (less time/energy) message transmission, multiple messages transmission in parallel Unique 32-bit device ID (device number) per LoRa member, unique 16-bit app ID (program number for the communication) Security – Login with SHA-256 encrypt password; AES-128 message encryption Air Traffic Control – Nodes only send if no LoRa signal is active on that channel. Optimized protocol – Message delivery within 110 ms (SF7, 125 kHz, free […]

ESPDUINO-32 & Wemos D1 R32 ESP32 Boards Support (Most) Arduino UNO Shields

The compact ESP32 NodeMCU like board are great for many project, but in case you plan to leverage your existing Arduino shield, it’s more convenient to have a compatible board. We’ve previously seen Noduino Quantum board sold for 99 RMB on Taobao, and $25.90 on AnalogLamb, but doit.am has designed a cheaper model called ESPDUINO-32 that supports shields compatible with Arduino UNO, and sold for $13.73 on DealExtreme. ESPDUINO-32 board specifications: Wireless Module – ESP-WROOM-32 based on Espressif ESP32 dual core Tensilica LX6 processor with 802.11 b/g/n WiFi and Bluetooth 4.2 LE Expansion – Arduino UNO headers with SPI, I2C, digital I/Os, 1x analog input up to 3.2V, 5V, GND USB – 1x USB device port Misc – Button Power Supply – 5 to 12V input via DC jack or Vin pin Dimensions – 66 x 53.3 x 13.5 mm The board can be programmed with the Arduino IDE selecting […]

LoFive is a Tiny Open Source Hardware Board based on SiFive FE310 RISC-V Open SoC

Do you remember HiFive1? It’s an Arduino compatible board based on the SiFive FE310 open source RISC-V SoC. Michael Welling has now started working on LoFive board using the same processor, but in a much smaller & breadboard friendly form factor. LoFive board specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 128-Mbit SPI flash (ISSI IS25LP128) Expansion – 2x 14-pin headers with JTAG, GPIO, PWM, SPI, UART, 5V, 3.3V and GND Misc – 1x reset button, 16 MHz crystal Power Supply – 5V via pin 1 on header; Operating Voltage: 3.3 V and 1.8 V Dimensions – 38 x 18 mm (estimated) The board will be programmable with Arduino IDE + Cinco just like HiFive1 board. The board is also open source hardware, so beside the aforelinked info on Hackster,io, you’ll also find the KiCAD schematics, PCB layout, and […]

Aspencore 2017 Embedded Markets Study – Programming Languages, Operating Systems, MCU Vendors, and More

Aspencore media group asked readers of their EE Times and Embedded.com websites to fill out an online survey about their embedded system projects. They got 1,234 respondents mostly from North America (56.3%), followed by Europe (25.2%), and Asia (10.6%). This resulted in a 102-page market study which you can download here. I’ve extracted a few slides to have a look at some of the trends. C language is still the most used language in embedded systems, but other languages like C++, Python and even assembly language are gaining traction. Operating system is more spread with Linux being the most used via Embedded Linux distributions, Debian, and Ubuntu. FreeRTOS comes in second place, while Android registers fourth with 13%. Git has finally supplanted Subversion in 2017, with all other version control software losing ground. Switching to some hardware slides, 44% used a development board to start their embedded design with ST […]
