Getting Started with TinyLIDAR Time-of-Flight Sensor on Arduino and Raspberry Pi

TinyLIDAR is an inexpensive and compact board based on STMicro VL53L0X Time-of-Flight (ToF) ranging sensor that allows you to measure distance up to 2 meters using infrared signals, and with up to 60 Hz. Contrary to most other VL53L0X boards, it also includes an STM32L0 micro-controller that takes care of most of the processing, frees up resource on your host board (e.g. Arduino UNO), and should be easier to control thanks to I2C commands. The project was successfully funded on Indiegogo by close to 600 backers, and the company contacted me to provided a sample of the board, which I have now received, and tested with Arduino (Leonardo), and Raspberry Pi (2). TinyLIDAR Unboxing I was expecting a single board, but instead I received a bubble envelop with five small zipped packages. Opening them up revealed three TinyLIDAR boards, the corresponding Grove to jumper cables, and a bracket PCB for […]

UltraZed-EG SoM and Starter Kit Feature Xilinx Zynq UltraScale+ ZU3EG MPSoC

Xilinx Zynq UltraScale+ Arm Cortex A53 + FPGA MPSoCs were announced in 2015, with actual products launched in early 2017 such as AXIOM development board or Trenz Electronic TE0808 UltraSOM+ system-on-module which are based on the ZU9EG model, and cost several thousand dollars. Recently, I wrote about Mycroft Mark II smart speaker based on a “quad core Xilinx processor”, and initially I assumed it was an Zynq UltraScale+ MPSoCs since those are the only Xilinx “quad core processors” I know of, but now I think it must be an unannounced part, since the company can’t provide the exact part number, and the price would be too low. Nevertheless, this lead me to check out if there was any lower cost boards based Xilinx Zynq UltraScale+ MPSoC with four Arm Cortex A53 cores, and ZU2EG is the entry-level part that matches this description. I could not find a ZU2EG development board, […]

Xiaomi Mi Box 4 & 4C 4K HDR TV Boxes Launched with Amlogic S905L Processor

Remember Amlogic S905L Processor? Me neither, but I wrote about it in September 2016, with the processor being an updated version of Amlogic S905X without VP9 support, and adding HDMI 2.0b output with support for Hybrid Log Gamma (HLG) HDR. One reason most people won’t remember it is because so far, no TV boxes featured the processor, but this has now changed with Xiaomi introduced Mi Box 4 & 4c TV boxes for the Chinese market. Xiaomi Mi Box 4c is the entry level model (Black color), and Mi Box 4 is slightly higher end with more memory and Bluetooth (White color), but both devices share most of the same specifications: SoC – Amlogic S905L quad core ARM Cortex-A53 @ up to 1.5GHz with penta-core Mali-450MP GPU @ up to 750 MHz System Memory Mi Box 4c – 1GB RAM Mi Box 4 – 2GB RAM Storage – 8GB eMMC […]

Linux 4.15 Release – Main Changes, Arm and MIPS Architectures

Linus Torvald has released Linux 4.15 last Sunday: After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me. Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny. So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue. Also, it is […]

Pine64 to Release RockPro64 Boards Based on Rockchip RK3399 and RK3399Pro for Around $60 and Up

Several Rockchip RK3399 boards have been announced in the last few days, first with AAEON RICO-3399 Pico-ITX single board computer targeting mostly business customers for digital signage, kiosk or, automation and Orange Pi RK3399, a featured-pack board with plenty of interfaces to play with. However those boards, and the one released previously, tend to cost between $100 and $200 or over, and even though we saw Rockchip SAPPHIRE evaluation board going for $75 its was a time-limited promotion, and the normal price is around $150. I’m pleased to report Pine64 will soon launch RockPro64 boards powered by Rockchip RK3399 or the recently announced RK3399Pro with an NPU for around $60 and up. There will be three versions of the board that will only differ by the processor, or RAM capacity: SoC (one or the other) Rockchip RK3399 hexa-core processor with 2x ARM Cortex A72 cores up to 2.0 GHz, 4x […]

Ericsson Unveils 5G Radio Dot for Better 5G Indoor Coverage

5G cellular technology is coming sometimes in 2019, before ramping up in 2020 in several countries. The new 3GPP standard will allow maximum bandwidth up to 10 Gigabit per second, and we’ve already seen announcements such as Snapdragon X50 5G Modem which will be able to reach up to 5 Gbps download speeds. 5G apparently works at either high bands starting at 28 GHz and up to 60 GHz, which means 5G signal might have a really hard time penetrating through walls or other obstacles, or at mid bands between 3.5 and 5 GHz which will still be a challenge compared to 4G LTE operating between 600 MHz and 3.5 GHz. That means that signal from outdoor base station won’t be able to penetrate in all building, so 5G indoor small cells will be necessary for good indoor coverage. Ericsson has already unveiled their own small cells with 5G radio […]

Orange Pi RK3399 Development Board Launched for $109

Orange-Pi-RK3399-Board-Description-Large

Last Friday, I wrote there was already a decent choice of Rockchip RK3399 boards, and added AAEON RICO-3399 pico-ITX board to the list. I forgot about Shenzhen Xunlong’s own Rockchip RK3399 board that was spotted as early as last spring and was told Orange Pi RK3399 was now up for sale for around $110 (699 CNY) in Taobao. The board is now also for sale on Aliexpress for $109 plus shipping ($4.35 here), and the company has released the specifications, so we can have a better look at what the board has to offer. Orange Pi RK3399 specifications: SoC – Rockchip K3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores up to 2.0 GHz, four Cortex A53 cores, and an ARM Mali-T860 MP4 GPU with support for OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL, and DX 11 System Memory – 2 GB DDR3 Storage – 16 GB eMMC flash, […]
