Tasmota Open Source ESP8266 Firmware Now Supports Zigbee Connectivity

Tasmota Zigbee to WiFi Gateway Prototype

Sonoff-Tasmota is a popular open-source firmware designed to run on ESP8266 hardware for home automation projects. It was initially designed to run on devices from ITEAD Studio Sonoff family but now supports more products, boards, and modules from other brands such as Shelly, Wemos, Blitzwolf, and others. So the first news is that the project has recently been renamed from Sonoff-Tasmota to just Tasmota, and documentation has been moved from Github Wiki to Github.io. Tasmota Zigbee Support A piece of more important news is that Tasmota now supports Zigbee. More specifically, the Z2T (Zigbee to Tasmota) concept allows you to make your own Zigbee to WiFi bridge by combining Z-Stack-firmware on CC2530 and Tasmota firmware on ESP8266 / ESP82xx hardware. Basically all you need is ESP82xx hardware connected to a Texas Instruments C2530 based Zigbee device over a serial. Note that C2531 based device won’t work since they are connected over USB. Normally, C2530 firmware is flashed through CC Debugger …

RAK7244 LoRaWAN Developer Gateway Combines Raspberry Pi 4 with LoRa HAT, Optional 4G LTE Connectivity

Raspberry Pi 4 LoRaWAN LTE Gateway

After launching RAK831 Lite LoRaWAN gateway based on Raspberry Pi 3 board in 2018, RAK Wireless introduced Pilot Gateway Pro RAK7243 gateway with the more recent Raspberry Pi 3B+ SBC earlier this year. But with the launch of Raspberry Pi 4 last June, the Raspberry Pi 3B+ has become much harder to procure, so RAK has now launched an updated LoRa gateway featuring Raspberry Pi 4 SBC together with the company’s RAK2245 Pi Hat Edition LoRaWAN gateway concentrator module. RAK7244 LoRaWAN Developer Gateway specifications: SBC – Raspberry Pi 4 Model B with 2GB RAM Connectivity LoRa RAK2245 Pi Hat LoRaWAN gateway concentrator module with 1x SX1301 baseband processor, 2x SX125x Tx/Rx front-ends LoRaWAN v1.0.2 support Support for 8 channels and spreading factors SF7 to SF12 Bands – 433MHz, 470MHz, 865MHz, 868MHz, 915MHz, 920MHz, 923MHz Tx Power: 27 dBm Max RX Sensitivity: -139dBm Cellular – Optional 4G LTE support via RAK2013 Cellular Pi HAT (Quectel EG95  LTE CAT4 module) GNSS – …

esp32MX-E ESP32 Board Comes with Ethernet and USB-C Ports (Crowdfunding)

ESP32 Ethernet & USB-C Board

We’ve already covered several ESP32 boards with Ethernet including Olimex ESP32-GATEWAY and Silicognition wESP32, and I’ve just noticed Espressif also made its own with ESP32-Ethernet-Kit. Modtronix Engineering has another take with esp32MX-E board that beside Ethernet also exposes a USB-C port, a MicroSD card slot, and also adds an STM32F0 microcontroller acting as an I2C I/O expander. esp32MX-E specifications: Wireless Module ESP32 dual-core LX6 microprocessor at 160 or 240 MHz, 4 MB Flash, 520 KB SRAM Wi-Fi 4 802.11 b/g/n Bluetooth 4.2 BR/EDR & BLE Storage – MicroSD card slot USB – USB Type-C connector for programming, power, and Virtual COM port Expansion via 14-pin and 20-pin female headers 22x I/O pins of which 4 are inputs only. 4x 5 V tolerant I/O pins Not all I/Os are available when the SD Card is used Programmable pull-up and pull-down resistors on most inputs Secondary MCU – I²C I/O expander implemented with a user-programmable STM32F030F4 Misc – User LED, button Power …

NanoPi R1S Dual Gigabit Ethernet Router Comes with 32-bit or 64-bit Arm Processor

NanoPi R1S Router

FriendlyELEC launched NanoPi R1 SBC & Gateway earlier this year with Allwinner H3 processor, two Ethernet ports, as well as WiFi and Bluetooth connectivity. The design makes use of both Ethernet on the processor, but that also means on Gigabit Ethernet port had to be combined with a Fast Ethernet processor. The company has now added a USB to Gigabit Ethernet bridge to their latest NanoPi R1S board meaning it’s now a dual Gigabit Ethernet SBC, but with the caveat that the port behind the USB bridge is limited to USB 2.0 speed (480 Mbps), and with overhead the USB Ethernet bandwidth is around 330 Mbps. There are two versions of the board, namely NanoPi R1S-H3 and R1S-H5 with respectively Allwinner H3 32-bit processor, and Allwinner H5 64-bit processor. Apart from the different processors, both boards share the same PCBA and specifications: SoC NanoPi R1S-H3 – Allwinner H3 quad-core Arm Cortex-A7 processor @ up to 1.2GHz with Mali-400MP2 GPU NanoPi …

Semtech SX1302 LoRa Transceiver to Deliver Cheaper, More Efficient Gateways

SX1302 Raspberry Pi Gateway

After our interview with Rak Wireless CEO, we received a comment inquiring about the availability of SX1302 gateways. Semtech so far had two LoRa transceivers for gateways namely SX1301 and SX1308, but I had never heard about a third one. Semtech SX1302 is brand new, the latest generation of baseband LoRa chip for gateways that is said to reduce current consumption in order to simplify the thermal design of gateways, as well as the BoM (bill of materials) costs), while being capable of handling a higher amount of traffic. Semtech SX1302 LoRa Transceiver Key features: Up to -141 dBm sensitivity with SX1250 Tx/Rx front-end 125 kHz LoRa reception with: 8 x 8 channels LoRa packet detectors 8 x SF5-SF12 LoRa demodulators 8 x SF5-SF10 LoRa demodulators 125 /250 / 500 kHz LoRa demodulator (G)FSK demodulator Direct interface to Semtech transceivers SX1255, SX1257 and SX1250 SPI host interface Single 32 MHz clock QFN68 Package Temperature Range – -40°C to +85°C.

Intel Denverton based Fanless Network Appliance Comes with 6x Ethernet Ports, 2x SFP Cages

PL-82000 Denverton Fanless Network Appliance

Intel Atom C3000 “Denverton” processors were introduced in 2016 for low power servers and network appliances with four to sixteen cores, and in the following years, many products based on the SoC were launched including GIGABYTE MA10-ST0 server motherboard, AAEON FWS-2360 desktop network appliance, and Supermicro A2SDi-2C-HLN4F Mini-ITX motherboard among others. New Denverton platforms did not get much coverage on CNX Software in the last couple of years, and an article on LinuxGizmos reminded me those still existed, as US-based WIN Enterprises recently launched LP-82000 fanless network appliance powered by Intel Denverton C3338, C3558, or C3758 processor and featuring six Gigabit Ethernet ports, as well as two SFP cages. LP-82000 specifications: SoC (one or the other) Intel Denverton C3338 dual-core processor @ 1.50 GHz / 2.20 GHz (Turbo); 4 MB cache; TDP: 8.5 W Intel Denverton C3558 quad-core processor @ 2.20 GHz; 8 MB cache; TDP: 16 W Intel Denverton C3758 octa-core processor @ 2.20 GHz; 8 MB cache; TDP: …
