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: …

Rockchip RK2108 Smart Audio Dock Converts Tablets into Smart Displays

Rockchip RK2108 Smart Dock

Last April, Rockchip published a roadmap to 2020 with processors such as RK3588 Cortex-A76/A55 or RK3530 quad-core Cortex-A55 SoCs. Part of the roadmap was also Rockhip RK2108 Arm Cortex-M4 microcontroller with an Audio DSP which did not get as much coverage. The company has now announced RK2108 based smart docks that convert tablets into smart display / speakers so that they can be waken-up and controlled by voice commands. Rockchip RK2108 audio MCU supports A/D audio interface, MIPI DSI/MCU LCD interface and USB2.0 interface, and comes with the following key features: Built-in audio DSP  for voice/audio signal processing Audio pre-processing, active noise reduction, AEC, etc… for improved voice recognition Customizable wake-up words and offline instructions Ultra-low power consumption in both standby and operating modes The RK2108 smart dock pictured above connects to compatible Android tablets over USB or Bluetooth, and turns those into smart display products that can handle voice commands more accurately and at lower power.

Olimex Launches NB-IoT DevKit Based on Quectel BC66 Module for 19 Euros

Olimex NB-IoT Devkit BC66

There are three LPWAN standards currently dominating the space LoRaWAN, NB-IoT, and Sigfox. In a recent presentation, Olimex explains NB-IoT (aka LTE Cat NB1) offers several advantages over LoRaWAN and Sigfox which include: Higher speeds of up to 25.5 kbps (UL/DL) Single GSM base station can handle up to 100 000 NB-IoT nodes Single GSM base station can cover up to 10-100km range in rural environments, and 1 to 10km in urban settings Lasts up to 10 years on a Lithium 3V battery if less than 200 bytes are sent per day The main disadvantage they listed was operator dependence, as you rely on the operator for coverage, and anything related to connectivity. In Bulgaria in particular, they found out it was not easy to get an NB-IoT SIM card activated, and the operator may shut you off without notice. For reference here in Thailand, last time I checked I could not buy a SIM card for evaluation with my …
