NanoPi M4 RK3399 SBC Price Drops to $50 and Up

The launch of Raspberry Pi 4 SBC has generated lots of interest, especially with the extra performance and low $35 price tag that has made most alternatives suddenly less interesting. However, Raspberry Pi 4 benchmarks show it’s not quite the fastest board around, and for example, Rockchip RK3399 platforms are still quite faster, sometimes as much as twice as fast. They do cost much more though, often more than twice, and so far one of the cheapest RK3399 boards was NanoPi M4 going for $65. FriendlyELEC has now decided, certainly in response to Raspberry Pi 4 offering, to lower the price to $50 for the 2GB RAM version which compares to $45 with Raspberry Pi 4 2GB, as well as $75 for the 4GB RAM version (was $95). NanoPi M4 specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 2.0GHz, 4x Cortex-A53 @ up […]

Khadas VIM3 SBC Launched with Amlogic A311D Processor, 5 TOPS NPU

We’ve previously written about Khadas VIM3 Amlogic S922X development board and revealed the price tag for VIM3 Basic ($69.99) and VIM3 Pro ($99.99) with a launch date announced for June 24. As time has passed, this has become “fake news” except for the launch date, as Khadas VIM3 SBC has indeed launched but for $99.99 (Basic) and $139.99 (Pro). What’s going on? Why the large price increase? That’s because Khadas team has decided to provide a more powerful platform to the community, and replace Amlogic S922X processor with Amlogic A311D processor boasting higher clock speeds and a 5.0 TOPS NPU. Another version may also become available later on with the soon-to-be-released Amlogic S922X-B processor whose Cortex-A73 cores are clocked at up to 2.2 GHz, instead of 1.7 GHz for the original Amlogic S922X processor that will be referred to Amlogic S922X-A in the future. New Khadas VIM3 SBC specifications: SoC […]

PanGu Board an SBC Based on the STM32MP1 Processor

The PanGu Board is a single board computer (SBC) that is feature-rich and versatile, at an affordable price point. The board powered by STMicroelectronics STM32MP1 processor was released in February of 2019 and hadn’t really made much a splash in the pool of microprocessors available at the time. The processor is now the main feature of the PanGu Board, an SBC with a host of features and utilizing the Arm dual-core Cortex–A7 MPU and the Cortex-M4 coprocessor to allow for more enhanced multimedia ability and all the heavy real-time processing that users are calling for today. Hardware Features MPU Dual Cortex-A7, 650MHz Cortex-M4, 209Mhz 3D GPU Flash & Memory 16-bit DDR3L, up to 1GByte 8-bit eMMC Flash Quad-SPI NOR Flash Supports Micro SD Audio 3.5mm stereo headphone jack support microphone input Display Parallel RGB LCD interface, the resolution up to WXGA (1366×768) MIPI DSI interface Support for resistive and capacitive […]

Raspberry Pi 4 vs Pi 3 – What are the differences?

So now that the Raspberry Pi 4 model B has just been launched, it may be worth checking out the differences against the previous latest single board computer from the Raspberry Pi foundation, namely Raspberry Pi 3 model B+. Let’s get straight to the Raspberry Pi 4 vs Pi 3 B+ comparison table. Features/Specs Raspberry Pi 4B Raspberry Pi 3 B+ Release date 24th June 2019 14th March 2018 SoC Broadcom BCM2711 quad-core Cortex-A72 @ 1.5 GHz Broadcom BCM2837B0 quad-core Cortex-A53 @ 1.4 GHz GPU VideoCore VI with OpenGL ES 1.1, 2.0, 3.0 VideoCore IV with OpenGL ES 1.1, 2.0 Video Decode H.265 4Kp60, H.264 1080p60 H.264 & MPEG-4 1080p30 Video Encode H.264 1080p30 Memory 1GB, 2GB, or 4GB LPDDR4 1GB LPDDR2 Storage microSD card Video & Audio Output 2x micro HDMI ports up to 4Kp60 3.5mm AV port (composite + audio) MIPI DSI connector 1x HDMI 1.4 port up […]

Raspberry Pi 4 Features Broadcom BCM2711 Processor, Up to 4GB RAM

Long expected, the Raspberry Pi 4 model B has finally launched, and it should not disappoint with a much more powerful Broadcom BCM2711 quad-core Cortex-A72 processor clocked at up to 1.5 GHz, 1 to 4GB LPDDR4, 4K H.265 video decoding and output support, a proper Gigabit Ethernet port, as well as USB 3.0 and 2.0 ports. Raspberry Pi 4 comes with all those extra features, but the form factor remains the same, and importantly the price is still $35 for the version with 1GB RAM, making Raspberry Pi alternatives suddenly much less interesting. Raspberry Pi 4 specifications: SoC – Broadcom BCM2711 quad-core Cortex-A72 (ARMv8) @ 1.5GHz with VideoCore VI GPU supporting OpenGL ES 3.0 graphics System Memory – 1GB, 2GB or 4GB LPDDR4 Storage – microSD card slot Video Output & Display I/F 2x micro HDMI ports up to 4Kp60 (Currently 1080p60 max. in dual-display configuration, although 2x 4Kp30 is […]

LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

If you are a fan of the Lego movie. Perhaps you have always wanted to use Lego bricks to make something innovative and techy. Then the Mini SAM M4 board is here for you, as it is a LEGO minifigure-sized development board. Additionally, the design and layout of the board is based around the classic 1980’s ‘spaceman’, and is made by Ben Shockley. Although the board is very small, it has a lot of wonderful features. It comes with an analog reference decoupling/filtering capacitors. Also, it has an analog to digital ferrite bead, as well as a debounce circuitry for the reset and user buttons. Furthermore, the board’s software and firmware can be developed using CircuitPython or Arduino. The development board is either based on the Microchip SAMD51G 48-Pin 32-Bit ARM – Cortex M4F MCU (Mini SAM M4), or features the Microchip SAMD21G 48-Pin 32-Bit ARM Cortex -M0+ MCU running […]

$9.9 ROCK Pi S is a Tiny SBC Powered by Rockchip RK3308 Processor

Radxa launched their low cost ($40) Rock Pi 4 SBC powered by Rockchip RK3399 processor a little over 18 months ago. If you are subscribed to their mailing list, the company has now sent an email entitled “ROCK Pi Summer Updates 2019” (no link available) that reports about v1.4 of the board with 4MB SPI flash onboard, an external WiFi antenna connector, and various other small changes, as well as the announcement of RockPi PoE HAT to power the board from an Ethernet cable, and an USB 3.0 eMMC card reader. But what particularly caught my attention in the email was a new tiny single board computer powered by Rockchip RK3308 Cortex-A35 processor: Rock Pi S selling for as low as $9.9 with 256MB RAM, and targetting headless IoT & smart voice applications. Rock Pi S board specifications: SoC – Rockchip RK3308 quad-core Arm Cortex-A35 processor with built-in VAD (Voice […]
