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

Khadas VIM3 Amlogic-A311D SBC

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 – Amlogic A311D hexa-core processor with 4x Arm Cortex-A73 cores …

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

Raspberry Pi 4 SBC

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 being worked on) 3.5mm AV port with composite video (and …

LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

Mini SAM Lego Board

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.
