LTE Cat M and NB-IoT Shield for Arduino Features SIMCom SIM7000-Series Module (Crowdfunding)

We’ve already covered several NB-IoT (and/or LTE Cat M1) Arduino shields with products like RAK Wireless WisLTE, Sixfab Arduino NB-IoT shield, or AIS NB-IoT shield, which all happen to come with Quectel modules. A young self-taught engineer has decided to make his own Arduino eMTC/NB-IoT shield, but based on a SIMCom SIM7000-series module instead of a Quectel one found in the other aforementioned products. Board specifications: Cellular Module (one of the list depending on your location) SIM7000A LTE Cat M1 & NB-IoT module certified for AT&T and Verizon in the US SIM7000C Cat M1/NB-IoT module with 2G/2.5G fallback for the Chinese market SIM7000E Cat M1/NB-IoT module with 2G/2.5G fallback for the European market Note: The developer is also looking into SIM7000G module which should work globally, but the option is not available for now Micro SIM card holder GNSS – GPS/GLONASS with 2.5m accuracy supported by SIMCom modules Antenna – […]

MX Pro 4K is an Android 7.0 TV Box powered by Allwinner H5 Processor

We’ve already seen Allwinner H5 processor in several development boards such as NanoPi NEO2, Orange Pi Zero Plus, or Libre Computer Tritium 2G among other. But while the processor has been designed for 4K OTT TV boxes, I had not seen any TV box based on the processor so far. MX Pro 4K, not to be confused by MXQ Pro 4K, changes that, as it features the quad core Cortex A53 processor combined with 1GB RAM, 8GB storage, and the usual HDMI, Ethernet, USB ports you’d expect from a TV box. MX Pro 4K specifications: SoC – Allwinner H5 quad core Cortex A53 processor with hexa-core Mali-450MP4 GPU System Memory – 1 GB DDR3 Storage – 8 GB eMMC flash (options: 4GB, 16GB, 32GB), micro SD card slot Video Output – HDMI 1.4b up to 4K @ 30 Hz, AV port (composite) Audio Output – HDMI, AV (stereo audio), and […]

Getting Started with IkaScope WiFi Pen-Oscilloscope, and ScanaQuad SQ50 USB Logic Analyzer & Signal Generator

A couple of weeks ago, I received IkaScope WS200 pen-like WiFi oscilloscope, as well as ScanaQuad SQ50 USB logic analyzer & signal generator, and I’ve already checked out the hardware both both in a aforelinked unboxing post. I had also very shortly tried IkaScope with GOLE 10 mini PC, but just to showcase potential use case for a Windows 10 mini PC with an inclined touchscreen display. But at the time I did not really a proper measurement, as it was more to test the mini PC than the oscilloscope itself. I’ve now had time to test IkaScope desktop program and mobile app in respectively Ubuntu 16.04 and Android 8.0.0, as well as ScanaStudio for ScanaQuad USB device using Ubuntu 16.04 only, since there’s no mobile version of the program. While I’ll focus on Ubuntu and Android, most of the instructions will be valid for Window 10 and Mac OS X […]

AcSiP S76G/S78G SiPs Integrate LoRa, GPS, and MCU into a Single 1.3×1.1 cm Package

LoRa has been combined with GPS in several products such as Rakwireless RAK811 LoRa tracker board, or Dragino LoRa/GPS HAT board among others, with all designed for far based on a LoRa module, plus a GPS module. LoRa GPS tracker will soon even smaller as AcSiP has developed S76G and S78G systems-in-package (SiP) that combine LoRa, GPS and an MCU into a single 1.1 x 1.3cm package. The two new modules are not listed on the company’s IoT-LoRa products page yet, but they appear to be an evolution of their S76S / S78S LoRa + MCU SiP released in 2016, so the new modules should have the following features: MCU – STMicro STM32L073x Arm Cortex M0+ MCU with up to 192 KB of Flash memory and 20 KB of RAM LoRa AcSiP S76G – Semtech SX1276 supporting global 868 MHz or 915 MHz ISM-Bands. AcSiP S78G – Semtech SX1278 supporting […]

$129 Allwinner R18 based 3-Mic Far Field Amazon AVS Development Kit in the Works

Several companies are already offering development kits for Amazon AVS (Alexa Voice Service), but as we’ve seen in the past, those are rather expensive with far-field kits such starting at $349 with kits such as Synaptics AudioSmart 4-Mic Development Kit, or Intel Speech Enabling Developer Kit, and hands-free kits being barely cheaper at $299 and up. But there will soon be a cheaper solution, as Allwinner and SinoVoIP (aka Banana Pi) are working on “SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS” that includes 3 microphones, and works without special DSP, relying instead on Allwinner R18 processor’s audio codec and capabilities. Allwinner SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS (aka R18-AVS-EVK) specifications: SoC – Allwinner R18 quad-core Cortex-A53 processor @ 1.15GHz with Mali400MP2 GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash Video Output – HDMI Audio – 6x Microphones, 2x AEC, AUX and headphone output; GMEMS voice […]

Rockchip RK3288 To Be Phased Out Soon? GPD XD+ Android Console To Get Mediatek MT8176 SoC, 4GB RAM Upgrade

[Update: I have now seen an email exchange with ASUS replying that Rockchip RK3288 will still be in production for 5 years, so GPD claims that manufacturing will stop for RK3288 may be incorrect, or misunderstood Update 2: Rockchip has now confirmed RK3288 will not be phased out. So I’m guessing there may have been info lost in translation with GPD simply not manufacturing their own RK3288 board anymore] Rockchip RK3288 32-bit Arm processor was first spotted in a company presentation in the summer of 2013, before being announced – with some confusion (Cortex A12 vs A17) – at CES 2014 in January. The quad core Cortex A17 processor had then its moments of glory with inclusion in products such as Chromebooks (2015), and ASUS Tinker board SBC earlier this year. Another product based on the processor is GPD XD Android game console, but according to a report on reddit, […]
