Jetson Mate Cluster box takes four Jetson Nano/Xavier NX modules

Jetson Mate Cluster Box

While we’ve seen plenty of cluster boards based on Raspberry Pi SBC or Compute Modules, I had never seen clusters of Jetson modules. Those already exist, and PicoCluster has a few, but what made me write this post today is Seeed Studio’s Jetson Mate cluster box equipped with a carrier board taking up to four NVIDIA Jetson Nano or Xavier NX modules, an enclosure covered with a largish cooling fan with RGB LED for good effect… Jetson Mate specifications: SoM compatibility – Jetson Nano or Jetson Xavier NX via four SO-DIMM sockets Video Output – HDMI 2.0 Networking Gigabit Ethernet (RJ45) port Microchip KSZ9896CTXC 6-port GigE Managed Switch for internal networking between the modules and to the outside world Camera – 2x MIPI CSI connectors USB – 4x USB 3.0 ports (one per module), 1x USB 2.0 port, 1x USB-C port for power Debugging – UART debug pins (4x pairs, […]

Hackboard 2 Intel Celeron N4020 SBC comes with optional 4G/5G cellular modem (crowdfunding)

Hackboard 2

We’ve seen several x86 SBCs made for the makers’ community including AAEON Up Board family, AMD powered UDOO BOLT boards, and Seeed Studio Odyssey-X864105 SBC and mini PC. Hackboard 2 is another one of those single board computers. Powered by a dual-core Intel Celeron N4020 Gemini Lake Refresh processor coupled with 4GB DDR4 RAM and 64GB eMMC flash, the board offers the usual HDMI, Ethernet, USB ports, plus a 40-pin Raspberry Pi header, and an optional 4G or 5G modem. Hackboard 2 specifications: SoC – Intel Celeron N4020 dual-core Gemini Lake Refresh processor @ 1.1 GHz / 2.8 GHz (Turbo) with 4MB cache, Intel UHD graphics 600; 6W TDP System Memory – 4GB DDR4 RAM Storage –  64 GB onboard eMMC flash, 2x NVMe M.2 slots for up to 4 TB additional storage Video output HDMI 2.0a output up to 4K 30-pin eDP connector for 11.6″ to 15.6″ displays 6-pin […]

Ollie USB board exposes isolated UART, CAN, USB, RS485 & RS232 interfaces (crowdfunding)

Ollie USB board

Just like months, we wrote about Tigard open-source USB FT2232H board for hardware hacking with easy access to OpenOCD, JTAG, Cortex, flashrom interfaces used to debug/flash boards, extra I/Os with UART, SPI, and I2C, as well as a header to connect a logic analyzer and observe signals. If the board does not exactly match your requirements, Ollie USB board might, also it may not serve exactly the same purpose(s). The board acts as a USB bridge to isolated UART (x2), CAN, USB, RS485, and RS232 interfaces. Ollie specifications: MCU – STMicro STM32F042 Arm Cortex-M0 microcontroller with CAN interface Host interface – Micro USB port Isolated interfaces (all with ESD protection) 2x UART ports up to 12 Mbps with 1.8/3.3/5 V voltage levels (set by slide switch) CAN bus based on CANable/CANtact open hardware, flashed with dual firmware CANtact and Candlelight (switch selectable) and equipped with termination resistor switch Downstream USB […]

RISC-V hardware & software ecosystem highlights in 2020

RISC-V hardware software 2020

The RISC-V Summit 2020 is currently taking place virtually, and RISC-V International, a non-profit corporation aiming to drive the adoption and implementation of the RISC-V instruction set architecture (ISA), took the occasion to remind us of the growth of the ISA both in terms of commercial adaption, education, and other projects. Calista Redmond, CEO of RISC-V International, detailed the growth in memberships: This year, our technical community has grown 66 percent to more than 2,300 individuals in our more than 50 technical and special interest groups. We’re seeing increased market momentum of RISC-V cores, SoCs, developer boards, software and tools across computing from embedded to enterprise … We’re proud of our growing global membership, which has more than doubled in the last year to 1,000 total members, including 222 organizations.” RISC-V also launched the RISC-V Exchange now listing over 124 RISC-V cores, SoCs, and developer boards, as well as 129 […]

What is Federated Learning in 5G C-V2X?

Implementation approach of Federated learning

In the past, Bluetooth, Wi-Fi, 3G, 4G with onboard sensors and GPS gave a huge start to the partial or conditional automation of the vehicles.  In today’s era of 4G/5G C-V2X (Cellular vehicle-to-everything) with onboard compute and sensors have pushed the connectivity evolution in the automotive industry. Work has increased on high-automation and fully autonomous vehicles. This is all possible due to wireless communication which is 5G. 5G brings high bandwidth, ultra-low latency, and high reliability to the board. With these promises, it becomes very evident that these technologies, specifically with 5G that can be leveraged in vehicles. The technology is not just to connect vehicles, but also tries to see if a vehicle can connect to a network to get some information from the cloud servers. For the use case of vehicles platooning, we can expect a latency of 10 ms with 99.99% reliability and a high data rate […]

$20 mini spot welder machine welds thin steel strips on battery packs

portable mini spot welder

When I think about welding machines, I imagine fairly large units, protective gloves and masks, plus sparks coming out of the welding process when two metal parts are melted together. So when I saw a small “portable DIY mini spot welder machine” going for $25 on Banggood[update: or just under $20 shipped on Aliexpress], I thought to myself: “what is THAT”? It turns out it’s made for welding jobs with thin nickel-plated steel strips such as the ones that can be found attached to 18650 batteries, or full battery packs. Mini spot welder specifications: Controlled with by unnamed MCU Display – LCD with welding parameters: WELD ENERGY – 01-99 adjustable by up and down keys INPUT – Display input power voltage WELD WAY – Manual / Auto (adjustable with “square label” button) Based on 5x 300A MOSFETs 30cm 10AWG cables for welding pens 25V 10000uF high-frequency low-resistance capacitor to increase […]
