RS485 sensor nodes are often used in smart agriculture, environment monitoring, or factory & building automation and work up to 1.2 km when using AWG 18 cables. If you already have such nodes but need to extend the distance, or would like to reduce the need for long cables, you could make use of Dragino RS485-LN RS485 to LoRaWAN converter which will work up to 10+ kilometers depending on conditions.

$55 ODROID-GO Advance Linux based Retro Game Console is Powered by Rockchip RK3326 Processor
Last year, Hardkernel took some time away from Arm and x86 Linux SBCs with the launch of ODROID-GO retro game console powered by Espressif Systems ESP32 processor. The console could be programmed with the Arduino IDE, and the $32 price tag made it a popular item despite the limited processing power fo the ESP32 dual-core processor. The good news is that the console got an upgrade with ODROID-Go Advance equipped with a Rockchip RK3326 quad-core Cortex-A35 processor coupled with 1GB RAM to run Linux, and featuring an upgraded 3.5″ wide-viewing angle color display. ODROID-GO Advance specifications: SoC – Rockchip RK3326 quad-core Arm Cortex-A35 processor @ 1.3GHz with Mali-G31 MP2 GPU System Memory – 1GB DDR3L @ 786Mhz, 32 Bits bus width Storage – 16MB SPI Flash for bootloader, Micro SD Card slot (UHS-1 Capable interface) Display – 3.5″ 320×480 TFT LCD (Wide-viewing angle display, MIPI-DSI interface) Audio – 3.5mm earphone […]

This Business Card is a $3 Linux Computer Powered by Allwinner F1C100s SoC
The smallest, thinnest Linux computer There are many business card-sized SBCs, like RPi 4. But George Hillard, an embedded systems engineer decided it would be interesting to build an actual business card that was a computer. His card runs Linux and houses an Allwinner F1C100s carrying an ARM9 processor with 32MB RAM and 8MB flash storage. The Basics It holds some of his photos, a copy of his resume and a couple of games, which is pretty good for something like a business card. There is a USB port off one corner, and the unit can connect to a computer and boot up in about 6 seconds and shows up under USB as a flash drive. But that piggybacked computer-attached display is really the only type of display the card can manage. The Shell and Linux Version The shell has the games, including a version of 2048, and a small […]
Zidoo M9 Mini PC Review – Part 1: Unboxing & Teardown
Over the years, Zidoo has made TV boxes for the consumer market, and digital signage players for businesses. The recently announced Zidoo M9 aims at both markets, plus other applications such as IoT, robotics, and artificial intelligence. Zidoo M9 is either sold as a board or a complete TV box reference design with a case, as it exposes all the usual ports of a TV with HDMI, USB, and Ethernet. But you can do more with internal connectors for cameras, PCIe interfaces, SIM card slot, MPI DSI and eDP connectors, and so on. The company has sent me a review sample, so let’s first check out the accessories provided with the box, and have a look into the hardware design today, before testing the Android firmware in the second part of the review. Zidoo M9 Unboxing The package makes it clear Zidoo M9 “mini PC” looks like a TV box, […]
Some Interesting Talks from FOSDEM 2020 Schedule
We wrote about IoT devroom call for proposals for FOSDEM 2020 a little while ago, and as the free open-source developer meetup is getting closer, FOSDEM 2020 organizers released the schedule. So I’ll look at some of the talks in the relevant devrooms such as the Internet of Things, hardware enablement, Embedded, Mobile and Automotive, as well as RISC-V and others to compose my own little virtual schedule for the 2-day event. Saturday, February 1 10:30 – 10:50 – How lowRISC made its Ibex RISC-V CPU core faster – Using open source tools to improve an open-source core – by Greg Chadwick Ibex implements RISC-V 32-bit I/E MC M-Mode, U-Mode, and PMP. It uses an in-order 2 stage pipe and is best suited for area and power-sensitive rather than high-performance applications. However, there is scope for meaningful performance gains without major impact to power or area. This talk describes work […]
