Toshiba TCKE9 reusable e-fuse features a fixed over-voltage clamp with adjustable overcurrent limit

Toshiba has recently introduced the Toshiba TCKE9 reusable e-fuse (electronic fuse) series, a new lineup of e-fuse ICs that can be used repeatedly, to protect power supply lines from various electrical faults like overcurrent, overvoltage, overtemperature, and short circuits. These new chips integrate various protection features into a single chip which simplifies circuit design and reduces component count compared to how a traditional protection circuit with multiple components is designed. This new line of products offers different ICs with different voltage ratings and adjustable current settings, alongside two reset modes auto-retry and latching. All these features make this e-fuse useful for applications like laptops, wearables, audio/video equipment, and industrial applications like automation systems, robotics, and many other applications. Toshiba TCKE9 reusable e-fuse Specification Input Voltage – 2.7V to 23V (Maximum – 25V) Output Current – 0 to 4.0A (Adjustable overcurrent limit – 0.5A to 4.0A via external resistor) ON Resistance […]

CrowView Note Review – A 14-inch laptop shell designed for Raspberry Pi 5 and Jetson Nano Developer kit

Elecrow CrowView Note is a laptop shell with a 14-inch Full HD display, an 84-key QWERTY keyboard with a touchpad, built-in speakers and microphone, and a 5,000 mAh battery that’s specially designed for the Raspberry Pi 5 and the Jetson Nano Developer Kit thanks to adapters. However, it can be used with any machine with either a full-featured USB-C port or spare USB and HDMI ports. So it works with any Raspberry Pi model, Windows, Mac OS, or Linux computers, Android smartphones, PS4/PS5 game consoles, and more. This type of laptop shell has been around for years with the first one being the Laptop shell for the Motorola Atrix 4G smartphone introduced in 2011, and more recently Nexdock launched a range of laptop shells such as the Neckdock XL 15.6-inch touchscreen display and wireless charging. The CrowView Note differentiates itself with its low price and direct compatibility with the Raspberry […]

Sipeed Lichee Book 4A 14-inch modular Linux laptop launched with TH1520 quad-core RISC-V processor

We’ve just written about Deep Computing’s DC-ROMA RISC-V Laptop II, but Sipeed has just launched the Lichee Book 4A modular RISC-V laptop based on the quad-core Alibaba T-head TH1520 processor and running Debian Linux. I was expecting the Lichee Book to launch with the SpacemIT K1 octa-core RISC-V processor, but Sipeed started with the time-tested TH1520 quad-core RISC-V processor coupled with up to 16GB RAM and 128GB eMMC flash and equipped with a 14-inch IPS display. In the future, we’ll get the Lichee Book 3A with the SpacemIT K1, and the Lichee Book 5A with an unnamed Cortex-A75-class RISC-V SoC with a 20 TOPS AI accelerator. Sipeed Lichee Book specifications: 260-pin SO-DIMM system-on-module (SoM) Sipeed LM3A – Upcoming module based on SpacemIT K1 octa-core RISC-V CPU (Cortex-A55 class) with 2 TOPS NPU Sipeed LM4A SoC – Alibaba T-Head TH1520 CPU Quad-core RISC-V Xuantie C910 (RV64GCV – RVV 0.7) processor @ […]

DC-ROMA RISC-V Laptop II with SpacemIT K1 octa-core SoC to run Ubuntu supported by Canonical

Deep Computing has announced the DC-ROMA RISC-V Laptop II powered by a 2.0 GHz SpacemIT K1 octa-core 64-bit RISC-V processor coupled with up to 16GB DDR4 and running Ubuntu with official support from Canonical. Deep Computing unveiled the first RISC-V laptop – named ROMA – in 2022 but it never really took off because of all the web3 and cryptocurrency features plus the ultra-high price. The new DC-ROMA RISC-V Laptop II does without those and features a 14-inch IPS display, a 1TB SSD, a WiFI 6 and Bluetooth 5.2 module, a webcam, several USB ports including a USB-C with DisplayPort Alr mode, and a “development interface” with a few GPIOs. DC-ROMA RISC-V Laptop II specifications: SoC – SpacemiT K1 CPU – 8-core X60 RISC-V processor @ up to 2.0 GHz; single-core performance equivalent to about 1.3x the performance of an Arm Cortex-A55 GPU – Imagination IMG BXE-2-32 with support for […]
