NanoPi R2S Dual Gigabit Ethernet SBC & Router is Powered by Rockchip RK3328 SoC

FriendlyElec launched NanoPi R1S router with two Ethernet ports based on either Allwinner H3 or H5 processor coupled with 512MB RAM last November. Both ports are “Gigabit” Ethernet port, but one is implemented via a USB 2.0 to Ethernet controller with a maximum bandwidth of around 330 Mbps. If you’d like to get two Gigabit Ethernet reaching close to 1 Gbps each, and your target application would benefit from a bit more memory, the company is now working on NanoPi R2S based on Rockchip RK3328 processor with 1GB DDR4 memory, one Ethernet port using the GMAC from the chip, and one Ethernet port relying one a USB 3.0 to Ethernet controller. The rest of NanoPi R2S specifications are pretty similar to the earlier board except WiFi is also gone: SoC – Rockchip RK3328 quad-core Cortex-A53 @ 1.5 GHz with Arm Mali-450MP2 System Memory – 1GB DDR4 RAM Storage – MicroSD […]

iWave Systems Launches NXP i.MX 8QuadMax / i.MX 8QuadPlus SBC

NXP i.MX 8 series family offers plenty of options from the i.MX 8X Cortex-A35 processor to i.MX 8QuadMax octa-core processor with two Arm Cortex-A72, four Arm Cortex-A53, and two Arm Cortex-M4F cores. We already covered plenty of i.MX 8 hardware on CNX Software, including a fair amount of i.MX 8QuadMax systems-on-module such as Toradex Apalis iMX8, iWave Systems iW-RainboW-G27M SMARC 2.0 SoM, Advantech ROM-7720 Qseven 2.1 computer-on-module, and others. But for some unknown reasons, there haven’t been that many i.MX 8QuadMax single board computer, and AFAICR we only wrote about Seco SBC-C43 board so far. But there’s now another option thanks to iWave Systems iW-Rainbow-G27S Pico-ITX SBC equipped with a choice of i.MX 8QuadMax or i.MX 8QuadPlus processor and up to 8GB RAM. iW-Rainbow-G27S specifications: SoC (one or the other)— NXP i.MX8 with VPU and HiFi4 DSP: NXP i.MX 8QuadMax with 2x Cortex-A72 cores, 4x Cortex-A53 cores, 2x Cortex-M4F real-time […]

Getting Started with Amlogic NPU on Khadas VIM3/VIM3L

Shenzhen Wesion released the NPU toolkit for Khadas VIM3/VIM3L last November, so I decided to try the latest Ubuntu 18.04 image and the NPU toolkit on Khadas VIM3L, before switching to VIM3 for reasons I’ll explain below. I’ve followed two tutorials from the forum and wiki to run pre-built samples and then building a firmware image and samples from source. Khadas VIM3L and VIM3 Have Different & Optional NPUs This will be obvious to anyone who read the specs for Khadas VIM3 and VIM3L that the former comes with a 5 TOPS NPU, while the one in the latter only delivers up to 1.2 TOPS. But somehow, I forgot about this, and assume both had the same NPU making VIM3L more attractive but this type of task, Obviously I was wrong. But the real reason I stopped using Khadas VIM3L can be seen in the photo below. My board is […]

Year 2019 in Review – Top 10 Posts and Stats

2019 is closing to an end, or you may already be into 2020 while reading this post. In any case, that means it’s time to look back at 2019 and look forward to the events and new products to take place next year. While 2018 was a boring year for new processors, 2019 brought us some interesting new chips such as Amlogic S922X / A311D, or the first Arm Cortex-A55 only processors such as Amlogic S905X3. Rockchip RK3399Pro was promising when it was announced last year, but it never really took off. It was a pretty quiet year for Allwinner as well. RISC-V architecture has been ramping up with the first general-purpose RISC-V MCU: GD32V, WCH CH572 Bluetooth LE MCU, the launch of more SiFive RISC-V cores, and Kendryte K210 RISC-V AI processor announced last year has found its way into more and more boards. There have also been the […]

OnLogic Introduces Four Apollo Lake Pico-ITX SBC’s with Integrated Heatsink

We previously covered some Apollo Lake Pico-ITX boards with the likes of GIGABYTE GA-PICO3350 or AAEON PICO-APL3 motherboards, but there are now more options with OnLogic – formerly known as Logic Supply – recently launching four Apollo Lake Pico-ITX SBC’s. OnLogic EPM160, EPM161, EPM162, and EPM163 are powered by either an Intel Celeron N3350 dual-core processor or an Intel Pentium N4200 quad-core SoC with different memory capacities, display and networking options. OnLogic EPM16x specifications: SoC EPM160, EPM161, EPM162 – Intel Celeron N3350 dual-core Apollo Lake processor @ 1.1 GHz / 2.4 GHz (Burst frequency) with Intel HD Graphics 500 EPM163 – Intel Pentium N4200 quad-core Apollo Lake processor @ 1.1 GHz / 2.5 GHz (Burst frequency) with Intel HD Graphics 500 System Memory / Storage EPM160 – 1 GB LPDDR4-2133, MicroSD card slot, mSATA (shared PCIe Mini Card slot) EPM161 – 2 GB LPDDR4-2133, 8GB eMMC flash, MicroSD card slot, […]

Banana Pi BPI-F2S Industrial SBC Launched for $58 with Linux 4.19 based Debian or Fedora OS

Last month we covered Banana Pi BPI-F2S single board computer (SBC) for industrial, IoT, and smart audio application that was powered by the intriguing SunPlus SP7021 “Plus1” processor featuring four Cortex-A7 cores, one ARM9 ARM9 real-time core, and one 8051 I/O controller core, as well as up to 512MB built-in DDR3 RAM. At the time, the board was not available, and we had limited information about software support, except the company would provide a Yocto-based Linux distribution. The good news is that you can now buy Banana Pi BPI-F2S industrial SBC on Aliexpress for $58 and Taobao for 390 RMB, and the company released source code and OS images for the board. Here’s a reminder of Banana Pi BPI-F2S specifications: SoC – Sunplus SP7021 “Plus1” with a quad-core Cortex-A7 processor @ 1.0 GHz, one Arm A926 microprocessor, an 8051 core to handle I/Os, and 128MB or 512MB DDR3 DRAM.

Testing NVIDIA Jetson Nano Developer Kit with and without Fan

A few weeks ago I received NVIDIA Jetson Nano for review together with 52Pi ICE Tower cooling fan which Seeed Studio included in the package, and yesterday I wrote a getting started guide showing how to setup the board, and play with inference samples leveraging the board’s AI capabilities. I’ll now test the board with the stock heatsink in both 5W and 10W modes, and see if thermal throttling does occur, and then I’ll fit the tower cooling fan to find out if we can extract more performance that way and how much lower the CPU temperature is. Jetson Nano Stress Tests with Stock Heatsink Let’s install SBC-Bench testing utility,

check it’s properly installed,
