How to Use 3G and GPS on Raspberry Pi with ThaiEasyElec 3G HAT Expansion Board

Venus Supply is an embedded systems company based in Bangkok, Thailand that sells products through their ThaiEasyElec website/brand, as well as a act as a local distributor for popular DIY electronics items. I previously tested their ESPino32 ESP32 board, and the company has now send me another of their new product called “3G HAT Expansion for Raspberry Pi” and based on Quectel UC20-G that support 3G and GPS/GLONASS connectivity globally, meaning it should work in any country with 2G or 3G coverage. After listing the specifications, going through unboxing and assembly with a Raspberry Pi 2/3 board, I’ll write some quick start guide to show what I had to do to use GPS and connect to 3G with a Hologram SIM card. 3G HAT Expansion for Raspberry Pi Specifications Quectel UC20-G wireless module supporting Cellular 3G – UMTS @ 800/850/900/1900/2100 MHz 2G – GSM @ 850/900/1800/1900 MHz Data – HSPA+ […]

Ericsson Unveils 5G Radio Dot for Better 5G Indoor Coverage

5G cellular technology is coming sometimes in 2019, before ramping up in 2020 in several countries. The new 3GPP standard will allow maximum bandwidth up to 10 Gigabit per second, and we’ve already seen announcements such as Snapdragon X50 5G Modem which will be able to reach up to 5 Gbps download speeds. 5G apparently works at either high bands starting at 28 GHz and up to 60 GHz, which means 5G signal might have a really hard time penetrating through walls or other obstacles, or at mid bands between 3.5 and 5 GHz which will still be a challenge compared to 4G LTE operating between 600 MHz and 3.5 GHz. That means that signal from outdoor base station won’t be able to penetrate in all building, so 5G indoor small cells will be necessary for good indoor coverage. Ericsson has already unveiled their own small cells with 5G radio […]

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 […]

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 […]
