Raspberry Pi CM4 boards offer dual Ethernet, 4G LTE

Raspberry Pi CM4 Dual Ethernet

Since the launch of Raspberry Pi CM4 and CM4Lite systems-on-module last October, we’ve seen carrier boards bring their own set of features including industrial communication interfaces, a stereoscopic camera, four SATA ports to build a NAS, a DIN-rail based industrial controller, and more. But so far, I have not seen a Raspberry Pi CM4 carrier board with dual Ethernet ports. Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4” was brought to our attention this morning, but there’s another one with 4G LTE connectivity, Fast+Gigabit Ethernet ports, and extra I/Os courtesy of MCUZone’s CM4-4G IO board. Let’s have a look at both of them. Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4 Specifications: Supported SoMs – Raspberry Pi CM4 and CM4Lite with up to 8GB RAM, 32GB eMMC flash, optional WiFi & Bluetooth Storage – MicroSD card slot to load OS on CM4Lite Video Output – Micro HDMI 2.0 port up to 4Kp60, […]

Pebble Tracker nRF9160 GPS & cellular IoT platform connects to IoTeX blockchain (Crowdfunding)

Pebble Tracker nRF9160 board

Nordic Semi nRF91-series of Cortex-M33 SoCs with NB-IoT and LTE-M (eMTC) cellular IoT connectivity was first unveiled in 2018. The first member of the family is nRF9160 System-in-Package (SiP) which also comes with GPS, and we’ve found it Nordic’s own Thingy:91 devkit, as well as in various modules and development boards from third parties. There’s now a new kit called Pebble Tracker that features Nordic Semi nRF9160 with NB-IoT, LTE-M, and GPS connectivity, as well as environmental, motion, and light sensors. The cellular IoT prototyping platform works with the IoTeX blockchain to design decentralized IoT solutions with higher security. Pebble Tracker hardware specifications: Wireless module – Nordic Semi nRF9610 SiP MCU Core -​ Arm Cortex-M33 @ 64 MHz Storage & Memory – 1 MB flash, 256 KB SRAM Connectivity – LTE-M / NB-IoT modem with support for bands from 700 MHz to 2.2 GHz) Security – Arm TrustZone IoT SIM card slot GNSS – TD1030 GPS receiver (time-multiplexed with LTE […]

Deutsche Telekom IoT Gateway combines LoRaWAN and LTE-M

LoRaWAN LTE-M IoT Gateway

I’d normally view LoRaWAN and LTE IoT standards such as NB-IoT or LTE Cat-M (aka LTE-M or eMTC) as competitors, but The Things Industries and Deutsche Telekom​ partnered to launch an IoT gateway with both LTE-M and LoRaWAN capabilities together with associated services. We do not have much information about the hardware, but it is a LoRaWAN gateway designed by MikroTik that connects to an LTE-M backhaul and to The Things Industries’ device and data platform. If the picture above does indeed represent the actual gateway it should also be equipped with two PoE capable Ethernet ports, and an RS485 terminal block, plus a USB port and a SIM card slot. The solution would mostly be used for smart buildings at first taking advantage of the superior signal penetration of LTE-M. Sensors would send data to the LoRaWAN gateway which then, would forward it to the cloud over LTE-M. This type of solution could also be achieved through traditional LTE […]

Calliope 2 – An LTE Cat-1 IoT platform with VoLTE support

Calliope 2 Chip

We have already seen Sequans’ Low Power LTE-M/NB-IoT Module – the Monarch 2. Sequans, popular for its product portfolio based on Monarch LTE-M/NB-IoT and Calliope Cat 1 chip platforms, has continued to release more products with the latest announcement of the Calliope 2 LTE Cat-1 Platform (Chip). This solution is designed for IoT applications that require a higher data rate of more than 100 kilobits per second. One of the key elements of the IoT industry is to choose a network connection that is cost-efficient and provides excellent coverage along with global coverage that enables roaming and voice over LTE (VoLTE) made possible with Cat 1.  Why having audio and voice for IoT applications you may ask? That’s mostly useful in machine-to-human and human-to-machine communications such as command, control, and alerts. “Calliope 2 complements our Monarch 2 LTE-M/NB-IoT product family and makes Sequans a one-stop-shop for virtually all IoT applications—ranging from simple low-speed sensor devices to higher speed security cameras, […]

Notecard LTE Cat-M / NB-IoT M.2 modem sells for $49+ with 10 years of connectivity

Notecard LTE Modem

If the IoT is ever going to take off, it needs low-cost hardware and connectivity. LoRaWAN is free, apart from the hardware costs, but for projects that need wider coverage and/or higher bitrate cellular connectivity is the way to go and we’ve seen in the past that Hologram offers a free developer SIM card for global IoT projects plus some low-cost cellular IoT plans, as well as 1CNE plans to offer a 10-year plan for 10 Euros. Blues Wireless has taken a different approach as they combine hardware and cellular connectivity with their Notecard LTE-IoT modems (LTE Cat 1/Cat M or NB-IoT) shipping for 10 years of connectivity for up to 500MB data. Notecard has four variants with the following key features and specifications: MCU – Arm Cortex-M4 MCU with 2MB flash Cellular connectivity NOTE-NBGL-500 – Narrowband Cat-M/NB-IoT/GPRS (Global) via  Quectel BG95-M3 modem NOTE-NBNA-500 – Narrowband Cat-M/NB-IoT (North America) via Quectel BG95-M1 modem NOTE-WBEX-500 – LTE Cat-1 (Global) via Quectel […]

ESP32 Board Features mini PCIe & SIM Card Sockets for 4G LTE Connectivity

ESP32 SIM Card T-PCIe Board Pinout Diagram

LilyGO has launched yet another ESP32 WiFi & Bluetooth IoT board. As its name implies, TTGO-T-PCIe board includes a mini PCIe socket that coupled with a SIM card socket allowing users to insert a 4G LTE mPCIe card to add cellular connectivity. The company also offers optional SIM7000 2G or SIM7600 4G LTE modems that come with LTE and GPS antennas. You should probably be able to add other cellular mini PCiE, as well as other wireless mPCIe modems for LoRa, Satellite communication, etc… (Finally most probably not) TTGO-T-PCIe board specifications: Wireless module – ESP32-WROVER-B with ESP32 dual-core wireless SoC with 520KB SRAM, WiFi and Bluetooth with on-board antenna, as well as 4MB flash, and 8MB PSRAM Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps (ESP32) Bluetooth 5.1 LE (ESP32) Optional wireless cards via mPCIe socket (I2C and UART), SIM card slot for 2G and 4G LTE cellular networking USB – 1x USB-C port, 1x 4-pin USB header Expansion […]

Particle Takes Pre-orders for its Cellular Tracking SoM, Evaluation Kit, and Tracker One Asset Tracker

Tracker Som Evaluation Kit

Earlier this year, Particle announced its Tracking System turnkey solution comprised of Tracker SoM LTE IoT module, Tracker One asset tracker with enclosure, as well as Particle Tracking Services software suite with geolocation services, fleet management, and an open device firmware application framework to integrate with off-the-shelf IoT sensors and enable OTA firmware updates. The hardware devices were expected for June/July 2020, and the company has now started to take pre-orders for Tracker SoM, its evaluation kit, and Tracker One for respectively $79.99, $99.99, and $127.99. Shipping is expected to start in August 2020. We already covered Tracker SoM in our initial article with the full specifications, but basically, it’s a Nordic Semiconductor nRF52840 powered module with 8MB flash, ESP32 for WiFI (including support for indoor location),  U-blox Neo-M8U GNSS module, and a choice of Quectel BG96 LTE CAT M1 module for the US or Quectel EG91-X CAT 1 module with 2G/3G fallback for EMEA region. We did not have […]

Orange Pi 4 SBC Gets a $16 4G LTE mini PCIe Card based on Rockchip RM310

Orange Pi 4 4G LTE Mini PCIe Card

Orange Pi 4 SBC is one of the most cost-effective Rockchip RK3399 SBC’s, as it sells for as low as $50 with 4GB RAM, Gigabit Ethernet, WiFi, and Bluetooth, HDMI 2.0 output, etc.. The board also comes with a 24-pin PCIe connector that’s not of much use on its own, so the company introduced a $4 PCIe adapter board providing access to a standard mPCIe socket and a SIM card slot so you could install your own. 4G mini PCIe cards can easily cost around $50 or more, but Shenzhen Xunlong Software has now launched its own 4G LTE mini PCIe card based on Rockchip RM310 module and sold for $16 on Aliexpress, excluding shipping. mPCIe card and RM310 module specifications: Frequency bands LTE-FDD – B1, B3, B5, B8 LTE-TDD – B38, B39, B40, B41 WCDMA – B1, B5, B8 GSM – 850, 900, 1800, and 1900 MHz Data rates 4G LTE – 150 Mbps DL, 50 Mbps UL 3G […]
