Turn Your Raspberry Pi into a “Smartphone” or Cellular IoT Gateway with PiTalk 3G HAT (Crowdfunding)

The Raspberry Pi boards are used in a countless number of projects, and some of those turn one of Raspberry Pi boards into a (thick) smartphone powered by Linux. The first one was probably PiPhone based on Raspberry Pi 1 Model B, and other followed suit such as TyTelli based on Raspberry Pi Model A+, and more recently ZeroPhone powered, as its name implies, by Raspberry Pi Zero board. UK based SB Components Ltd is offering another option with their PiTalk HAT based on a Quectel 3G UMTS module, and kits adding a 3.2″ to 5″ display, an optional camera, and/or Raspberry Pi 3 board. PiTalk board specifications: Cellular Connectivity Quectel UC15 3G/2G UMTS/HSDPA and GSM/GPRS/EDGE module with up to 3.6 Mbps download, 384 Kbps upload SMA antenna connector Push push SIM card holder Voice, SMS and data support Audio – 3.5 mm audio jack, speaker and mic support via […]

Riot Micro RM1000 NB-IoT and eMTC Baseband Chip Unveiled for the Cellular IoT Market

Telecommunication providers don’t intend to let newcomers like Sigfox or Semtech (LoRa) get all the fun and money with the Internet of Things, and that’s why LTE Cat M1 (eMTC) and Cat NB1 (NB-IoT) have been standardized. We have already covered module and silicon vendors products such as U-blox SARA-R4 / SARA-M2 modules, or Mediatek MT2625 SoC supporting the new protocols defined in 3GPP release 13 specifications. U-blox even have a module that supports both NB-IoT and eMTC in a single chip, but they are not alone anymore, as a startup called Riot Micro introduced RM1000 baseband NB-IoT & eMTC chip. RM1000 key features & specifications: MCU – ARM Cortex-M0 processor Storage – QSPI Flash interface Connectivity LTE-M Baseband supporting 3GPP Release 13 NB-IoT Baseband supporting 3GPP Release 13 SIM interface with power control Peripherals Digital data and control interface to popular RFICs (RBDP/DIQ/SPI) 3x UART interfaces General purpose I/O […]

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 […]

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 […]

Giveaway Week – Wio GPS Tracker Board

It’s Friday, and the fifth day of giveaway week on CNX Software. Today, I’ll be giving away Wio Tracker, an Arduino compatible board based on Microchip / Atmel SAMD21 ARM Cortex M0 MCU with GPS, Bluetooth, 2G GSM/GPRS connectivity. My review of the board was rather negative, as I only managed to make Bluetooth 3.0 work while following the documentation as it was back in May. Since then the documentation seems to have improved, and other people have been more successful than me, and made the blink LED, and GPS samples to work. This version of the board only support 2G, so make sure it is still supported in your region/country. To enter the draw simply leave a comment below. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or email address. Contests are open for 48 hours starting at […]

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 […]
