Mediatek MT2621 Supports Dual Mode NB-IoT and GSM/GPRS for IoT, Wearables, and Industry 4.0

Mediatek introduced MT2625 ARM Cortex-M SoC supporting NB-IoT (aka LTE Cat NB1/NB2) compatible with 3GPP Release 14 last summer, and designed for global cellular IoT devices. The company has now unveiled a new NB-IoT part with Mediatek MT2621 ARM7 dual-mode IoT SoC that is capable of both NB-IoT R14 and GSM/GPRS connectivity for applications such as smart trackers, wearables, IoT security, smart metering and industrial applications. The chip would allow you to start deploying devices with GSM connectivity, and once available in your locale, switch to the more efficient NB-IoT protocol. Mediatek MT2621 specifications: Processor – Single ARM7 core @ up to 260MHz Memory – 160KB + 4MB PSRAM Internal Flash Connectivity Integrated Baseband, RF, Antenna, and Modem DSP NB-IoT ultra-low/low/mid bands defined by 3GPP Rel-14 GSM/GPRS Bluetooth 4.2 Display – LCM interface Camera – Camera interface Audio – Audio Amplifier Integrated PMU Mediatek is really light on details, but […]

Netgate SG-3100 is an ARM based pfSense Firewall Appliance

pfSense software is a popular open source firewall distribution based on FreeBSD operating system that is entirely managed via a web interface. Up until recently, FreeBSD (see comments section) pfSense would only support x86-64 (Intel or AMD hardware). But progress has been made with pfSense (and FreeBSD) for ARM, and Netgate, the company behind pfSense, is now selling two ARM based firewall appliances with SG-1000 microFirewall powered by Texas Instruments AM3352 Cortex A8 SoC, and sine a little over of month,  SG-3100 firewall appliance based on a more suitable Marvell dual core Cortex A9 processor. Netgate SG-3100 hardware specifications: Processor – Marvell ARMADA 38x 88F6820 dual core ARM Cortex-A9 @ 1.6 GHz with NEON SIMD and FPU System Memory – 2GB DDR4L Non ECC Storage – 8GB eMMC Flash Network Interfaces 2x Gigabit Ethernet configured as dual WAN or one WAN one LAN 4x ports Gigabit Marvell 88E6141 switch, uplinked […]

Compulab IOT-GATE-RPi Industrial IoT Computer is Powered by Raspberry Pi CM3 Module

We’ve seen several industrial products powered by Raspberry Pi 3 board or CM3 module recently, with the likes of Industrial Shields Panel PC, TECHBASE ModBerry, or Pi/104 PC/104 compliant carrier board among others. We can now add another industrial computer based on Raspberry Pi CM3 module with Compulab IOT-GATE-RPi IoT gateway, with dual Ethernet port, support for 3G/LTE modems, a rugged case, and working in a wide temperature range of -40°C to 80°C. Compulab IOT-GATE-RPi specifications: SoC –  Broadcom BCM2837 quad-core Cortex-A53 @ 1.2GHz with VideoCore IV GPU System Memory – 1GB LPDDR2 Storage – 4 to 64GB of soldered eMMC flash,  micro SD socket Connectivity 2x 100Mbps Ethernet WiFi 802.11b/g/n, Bluetooth 4.1 BLE 3G / LTE cellular modem via mini-PCie module) Video Output – HDMI 1.3, up to 1920×1080 Audio – 3.5mm stereo line out jack, HDMI audio USB – 4x USB2.0 host port Serial 1x RS232 port, ultra-mini […]

SixFab Launches Raspberry Pi 3G-4G/LTE Base Shield V2 for $31.20

Development boards with 4G LTE are still quite expensive, at least compared to 2G or 3G solutions, with for example Wio LTE GPS Tracker board selling for around $100. So when I saw Sixfab introducing a 3G/4G shield for Raspberry Pi 3 for just $31.20 (pre-orders), I first thought it was an incredible deal. But I soon realized I missed the “base” word in the name, as the shield just includes the SIM card slot, and mPCIe connector where you can connect Quectel’s UC20-G Mini PCle 3G module or EC25 Mini PCle 4G/LTE Module which adds respectively $59 or $89 to the price. That’s still an interesting HAT board, so let’s have a look. Raspberry Pi 3G-4G/LTE Base Shield V2 specifications: Clip-in Mini PCIe socket for: 4G/LTE Module (Quectel EC25) up to 150Mbps downlink and 50Mbps uplink data rates, GPS/GLONASS 3G Module (Quectel UC20) up to 14.4Mbps downlink and 5.76Mbps […]

Hologram Unveils Nova 3G USB Dongle and Python SDK; 200 Raspberry Pi Zero W Kits Given Away to Developers

This summer I discovered Hologram global cellular IoT SIM card, and since they provided free developer samples with 2MB of monthly data includes, I decided to get one to try it out. I received it a few weeks later, and to my surprise it worked, despite my country of residence having some strict requirements with regards to SIM card registration. The SIM card uses roaming, but with a low fixed worldwide pricing, and does not come with a phone number by default, so maybe that’s why I did not have to register. The company is now back with Nova, an open source hardware cellular modem certified by OSHWA (ID #US000077). It’s basically 2G/3G USB dongle that’s controlled by Hologram Python SDK, specifically suited to Debian systems like Raspberry Pi 3 or BeagleBone Black. Hackster.io is also involved in the launch with a worldwide contest offering 200 free kits comprised of […]
