FNIRSI 1013D teardown and mini review – A portable oscilloscope based on Allwinner CPU & Anlogic FGPA

The FNIRSI 1013D is a dual-channel flat-panel oscilloscope with a rich set of features. It is cost-effective and useful to people in the maintenance and R&D industries. Although it has been on the market for a few years, I purchased one, and I decided to introduce it and disassemble it to check out the hardware design. FNIRSI describes its oscilloscope as “small and portable”, so I assume it should include a lithium battery, a TFT LCD screen, a processor to handle the display, and another chip to process the digital signals. Let’s take it apart first to find out. FNIRSI 1013D oscilloscope unboxing FNIRSI 1013D package content: 1x FNIRSI 1013D oscilloscope 2x 100MHz matching probes (1X and 10X) 1x USB cable 1x Charging adapter 1x Instruction manual The FNIRSI 1013D adopts a 7-inch 800 x 480 resolution color TFT LCD with a capacitive touch screen. There are two input channels […]

AXERA AX620A 4K AI SoC delivers up to 14.4 TOPS for computer vision applications

AXERA AX620A is a high-performance, low-power AI SoC with a quad-core Arm Cortex-A7 processor and a 14.4TOPs @ INT4 or 3.6TOPs @ INT8’s NPU that is slightly inferior to the Amlogic A311D, and mainly used for AI vision applications. With high computing power and built-in image processing capabilities, the AX620A can support a wide range of AI workloads. It also offers low power consumption with low standby power and fast wake-up, so the chip can be integrated into battery-powered products. AXERA AX620A specifications: CPU – Quad-core Arm Cortex-A7 @ 1.0 GHz with 32KB L1 I-cache + 32KB L1 D-cache per core, 256KB L2 cache, FPU and NEON NPU – 14.4 TOPS @ INT4, 3.6 TOPS @ INT8 with support for Imagenet, AlexNet, VGG, ResNet, GoogLeNet, Faster R-CNN, SSD, FPN, Yolo V3, and other neural networks. ISP Proton AI-ISP up to 4Kp30 4 channels of camera support up to 4x 1080p30 Support […]

DongshanPI-D1s – An Allwinner D1s RISC-V development board designed to teach programming

The DongshanPI-D1s development board is comprised of a soldered-on Allwinner D1s RISC-V system-on-module board (SoM) and a carrier board with two 40-pin headers and a 2.0mm dedicated header. This development board is specifically designed to teach programming with a focus on the RISC-V architecture. The development board was designed by 100ask. They previously designed the Dongshan NeZha STU a development board based on the Allwinner D1. The main difference between the two is that 100ask did not include the Ethernet and HDMI interfaces on the DongshanPI-D1s board. The pinout of the headers is also slightly different because they opted to make the headers compatible with the widely used 40-pin GPIO from Raspberry Pi single board computers. DongshanPI-D1s preliminary specifications: D1s Core Lite SoC – Allwinner D1s single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with with 32 KB I-cache + 32 KB D-cache Memory – 64 MB DDR2 (SIP) […]

BIGTREETECH CB1 – A Raspberry Pi CM4 compatible Allwinner H616 system-on-module

The BIGTREETECH CB1 core board is an Allwinner H616 quad-core Arm Cortex-A53 system-on-module (SoM) that follows the Raspberry Pi CM4 form factor and was designed by BIGTREETECH, a company whose main business is related to 3D printer motherboards and their peripherals. The BIGTREETECH CB1 comes with 1GB RAM, an HDMI output interface, 2.4GHz WiFi, and 100Mbps Ethernet. The CB1 has better multimedia capability than the CM4 with support for 4Kp60 H.265/H.264 video decoding and 1080p60 H.264 video encoding, while the Broadcom BCM2711 processor on the CM4 can only handle 4Kp60 H.265 and 1080p60 H.264 video decoding, and 1080p30 H.264 video encoding. Some disadvantages include the lack of CSI and DSI interfaces on the Allwinner H616 system-on-module and the presence of only one video output interface against two for the Raspberry Pi CM4 module. BIGTREETECH CB1 specifications: SoC – Allwinner H616 quad-core Cortex-A53 @ 1.5GHz with Mali-G31 MP2 GPU with OpenGL 3.2, […]
