Khadas VIM3L (Amlogic S905D3) Benchmarks, Settings & System Info

Khadas VIM3L Heatsink

Khadas VIM3L is the first Amlogic S905D3 SBC on the market and is sold as a lower-cost alternative to the company’s VIM3 board with a focus on the HTPC / media player market. Shenzhen Wesion was kind enough to send me a sample for review, and I’ll start by checking out benchmarks and system information in Android 9.0 Pie operating system. I also plan to perform a more detailed review with Android 9.0 and CoreELEC with a focus on media playback. I received the bare board only, and the first thing I did was to install it the heatsink I received for VIM3 and in turn, install it in the acrylic case. The company told me the heatsink is not really necessary “for normal purpose using like watch TV”, but it should be installed for performance tests and heavy workloads. I’d still recommend purchasing the heatsink to make sure it works well during the summer months as well. Upgrading Android …

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 …

Novasom M7+ SBC Adds FFC HDMI Connector, USB & RS-485 Headers, Improves on Raspberry Pi 3 SW Compatibility

Novasom M7+

We previously wrote about Novasom M7 Rockchip RK3328 SBC being promoted as a drop-in replacement for Raspberry Pi 3 in industrial projects. That’s despite the different port arrangement, and instead, the company bases the claim on the availability of the 40-pin header, mounting holes matching RPI 3 board design, as well as software compatibility thanks to a library that allows customers to re-use the code written for Raspberry Pi boards. Based on feedback from customers, the company has made some changes to their design and launched Novasom M7+ SBC, and made several improvement to the software to be even more compatible with Raspberry Pi 3 board. Specifically there are five changes: Ability to power the board via the USB type-A port (5V) as an alternative to the 12V power barrel jack Stronger Backlight Driver for display  up to 6A @5V) t FFC cable for HDMI output – The dimension of the HDMI cable and its rigidity may make it hard …
