RAKwireless programmable 5G & LoRaWAN small cell device runs Ubuntu on Raspberry Pi CM4

RAKwireless “All-in-One 5G” is a programmable 64-bit Ubuntu indoor device that integrates AGW (access gateway) through a Raspberry Pi CM4 as well as 5G and 4G LTE cellular and LoRaWAN connectivity. The device is powered through its 2.5GbE PoE++ port and designed for private 5G networks for industrial automation, public safety, and transportation, and RAKwireless says you can also “start earning cryptocurrency by providing LTE cellular and LoRa coverage”, but I could not find details about monetization at this time. RAKwireless “All-in-One 5G” specifications: SoM (AGW) – Raspberry Pi CM4 system-on-module with Broadcom BCM2711 quad-core Cortex-A72 processor with 4GB RAM and 32 eMMC flash, WiFi 5 and Bluetooth 5.0 connectivity 5G/4G cellular connectivity LTE Mode- TDD Frequency Bands – Band 48 (3550 MHz to 3700 MHz); band N78 is also supported for global coverage Channel Bandwidth5/10/15/20 MHz Max TX Power – 24 dBm Receiver Sensitivity – -100 dBm Built-in 2-port […]

Embit EMB-LR1280-mPCIe-4x is a 2.4GHz LoRa mPCIe module based on Semtech SX1280 chipset

Embit EMB-LR1280-mPCIe-4x is an mPCIe (mini PCIe) module based on four Semtech SX1280 2.4 GHz LoRa transceivers and designed for OEM gateways that can work worldwide thanks to the use of the 2.4GHz ISM band and supports ranging. We first covered 2.4GHz LoRa and the SX1280 transceiver two years ago as a solution to design region-independent products specially suited to maritime and intercontinental logistics applications. We haven’t seen it used that much although we covered an ESP32 board with SX1280 last year, and it turns out that Italian company Embit has also made a mPCIe module based on the SX1280 chipset. Embit EMB-LR1280-mPCIe-4x specifications: LoRa connectivity Chipsets – 4x Semtech SX1280 transceiver with 3x LoRa Rx Channels + 1x LoRa Tx Modulation – LoRa Spread Spectrum Frequency – 2.4 GHz ISM band Frequency Range – 2400 to 2500 MHz RF Output power – Up to +12 dBm Sensitivity -129 dBm […]

433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors

CNXSoft: This is a guest post by Florian Robert (1technophile) of the OpenMQTTGateway project about using a 433 MHz LoRa transceiver on an ESP32 board for home automation, specifically to talk to 433 MHz sensors Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car. If we want to be specific, we can talk about the different radio frequencies (433 MHz, 915MHz, 868MHz, 315MHz, or 350MHz) and signal modulations OOK, ASK, FSK that we encounter behind the keyword 433MHz.

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.

EdgeBox-ESP-100 – An ESP32-S3 industrial controller with RS485, CAN Bus, DIO, 4G LTE, and more

We’ve previously covered the EdgeBox-RPi4 industrial controller powered by a Raspberry Pi Compute Module 4 and plenty of I/Os such as RS485, RS232, digital inputs and outputs, and connectivity options such as Gigabit Ethernet, WiFi 5, Bluetooth 5, and 4G LTE. But if you don’t quite need the power of a Linux controller, the EdgeBox-ESP-100 industrial edge controller based on an ESP32-S3 dual-core WiFi and Bluetooth microcontroller and offering a similar set of features, albeit with twists, may be an interesting option. EdgeBox-ESP-100 specifications: Microcontroller – Espressif Systems ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240 MHz with AI vector instructions, 512KB RAM Memory – 8MB PSRAM Storage – 16MB Flash Network connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth 5.0 LE via ESP32-S3 4G LTE cellular via SIMCom A7670G LTE Cat 1 module Optional support for LoRa (replaces the A7670G module) Serial & I/Os via terminal blocks […]

ModBerry 500 R1 industrial computer replaces Raspberry Pi CM4 with Radxa CM3 module

The ModBerry 500 R1 industrial computer features a Radxa CM3 system-on-module that follows the Raspberry Pi CM4 form factor, but is powered by a Rockchip RK3566 quad-core Cortex-A55 processor instead. The ModBerry 500 CM4 DIN-rail industrial computer with a Raspberry Pi Compute Module 4 was launched in 2020, but the Raspberry Pi shortage got in the way, even for commercial customers, and Poland-based TECHBASE had to find an alternative to Raspberry Pi CM4 to offer shorter lead times to its customers, and so the ModBerry 500 R1 based on Radxa CM3 system-on-module was born. ModBerry 500 R1 specifications: SoM – Radxa CM3 module with Rockchip RK3566 quad-core Cortex-A55 processor @ up to 2.0 GHz, with 1 to 8GB LPDDR4 RAM, up to 4 to 128GB eMMC flash (up to 250 MB/s), optional Wi-Fi 5 & Bluetooth 5.0 module Storage – Optional NVMe SSD via PCIe 2.0 (mini PCIe (default) or […]

Wi-SUN: An LPWAN standard for Smart Cities, Smart Agriculture, large scale IoT deployments

Wi-SUN is a standard (IEEE 802.15.4g) managed by the Wi-SUN Alliance and designed for Smart Cities, Smart Agriculture, and other large scale IoT deployments with a large number of devices thanks to the use of IPv6 mesh networking. The organization was founded in 2011 to “support the worldwide development of Wireless Communications Networks for Utilities, Smart Cities and IoT”, but due to the niche nature of target applications, it does not get that much press coverage and was only recently brought to my attention. Wi-SUN stands for “Wireless Smart Utility Networks”or “Wireless Smart Ubiquitous Networks”, and the standard aims to connect streetlights, cameras, weather stations, smart metering, utility transmission systems, and others to enable data-sharing between city services to improve their efficiency, save costs, and offer improves services to citizens. Wi-SUN FAN (Field Area Network) is the latest protocol managed by the Wi-SUN Alliance with over 95 million units shipped […]
