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 […]

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 […]

Raspbian for Raspberry Pi Boards Gets Upgraded to Debian Stretch

While Raspberry Pi boards support many different operating systems, Raspbian is by far the most popular option, and in the last two years the distribution was based on Jessie (Debian 8), the Raspberry Pi foundation has just announced it was now replaced by an update to Stretch (Debian 9). The Jessie version is completely gone from Raspbian Download page, and you’ll only be offered to download “Raspbian Stretch with Desktop” or “Raspbian Stretch Lite”. So what has changed compared to Jessie? Debian 9 changelog will list the main differences compared to Debian 8, but some modifications have also been made in Raspbian itself: Version 3.0.1 of Sonic Pi “Live Coding Music Synth” app – See changelog Chrome 60 stable with improved memory usage and more efficient code Bluetooth audio is supported by the bluez-alsa package by default instead of PulseAudio Better handling of “non-pi users”, as previously many applications assumed […]

Pine64 SoPine Cluster Board Takes up to Seven SOPINE A64 Systems-on-Module

Pine64 launched SOPINE A64 system-on-module based on Allwinner A64 processor back in January, with such module normally being found in low volume products where companies do not want to spent too many resources developing complex multiple layers boards with CPU and RAM, and instead focus on developing a simpler baseboard and custom software for their product. Pine64 made something else with SOPINE A64 modules:  a cluster board. I don’t have the full details yet, but “PINE64 SoPine Cluster Board” comes with 7 SO-DIMM slot designed to take SOPINE64 modules with the board providing a micro USB OTG port, a USB host port, and Ethernet transceiver for each SoM, which are connected to a Gigabit Ethernet switch (initially Marvell 88E6185, but they appear to have now switched to a Realtek part), and accessible via a single Gigabit Ethernet port. Power can be provided by a 5V/10A power supply connected to a […]

Intel’s Movidius Neural Compute Stick Supports Raspberry Pi 3 Board

Last month, Intel introduced Movidius Neural Computer Stick to accelerate applications such as object recognition, and do so offline, i.e. without the cloud, and at low power. While there was not that much information available at the time, the minimal requirements for the host machine were that it had to be a x86_64 computer running Ubuntu 16.04, and come with at least 1GB RAM, and 4GB storage. So I understood the stick would only work attached with 64-bit Intel or AMD processors, and ARM development boards would not be an option. But today, I’ve found that Movidius had uploaded a new video showing a Python based object recognition demo with the Neural Compute Stick connected to the the Raspberry Pi 3 board. You just need to add a USB camera, copy ncapi directory from the SDK installed on your Ubuntu 16.04 development machine to the Debian Jessie installed on RPi 3 […]
