$20+ NanoKVM is a tiny low-power RISC-V KVM over IP solution

Sipeed NanoKVM is a tiny KVM over IP solution based on the Lichee RVNano RISC-V microcontroller board that offers most of the features provided by the popular Raspberry Pi 4-based PiKVM solution allowing users to fully remote control a host such as a computer, server, or SBC down to the BIOS level and power on/off. Two variants are available, namely the NanoKVM Lite and NanoKVM Full. Both support up to 1080p60 displays, virtual USB keyboard and mouse, USB storage emulation, Ethernet with Wake-on-LAN, and IPMI (Intelligent Platform Management Interface) through serial interfaces, but the Full version also adds a resin enclosure, 0.96-inch information display, ATX power control through USB-C port, a microSD card with the firmware, and optional WiFi or PoE support Sipeed NanoKVM specifications: SBC – Sipeed RVNano SoC – SOPHGO SG2002 Main core – 1GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (the latter is likely not used […]

SkyByte Mini Wi-Fi-controlled drone runs the open-source ESP32-Drone firmware (Crowdfunding)

The SkyByte Mini is a simple, miniature drone powered by the ESP32-WROOM-32 WiFi and Bluetooth module, and comprised of an MPU6050 inertial measurement unit, coreless motors, and plastic propellers. The Espressif ESP32-WROOM-32 module on the board provides a wireless connection that can be used to control the drone from a mobile app. The printed circuit board uses an “all-in-one” design that removes the need for 3D-printed parts and makes for a more compact final product. The drone’s functionality can be extended with external sensors to suit desired applications. It can be used for hobbyist and educational purposes. SkyByte Mini drone specifications: Wireless Module – ESP32-WROOM-32 module, dual-core Tensilica processor, with integrated Wi-Fi + Bluetooth 4.2 LE Motor control – 4x SI2302 N-Channel 20V MOSFET USB – USB-C port for power and programming Sensor – TDK Invensense MPU6050 IMU 3-axis gyroscope and 3-axis accelerometer Misc- 3x debugging LEDs, 1x power LED, […]

SONOFF SNZB-05P review – A Zigbee water leak sensor tested with eWelink and Home Assistant

Today, we will review another new sensor from SONOFF, the SNZN-05P Zigbee water leak sensor. This is SONOFF’s first-ever water leak detection sensor. In the past, we have reviewed other Zigbee sensors that were upgraded from previous models. SONOFF enthusiasts will likely be pleased because a water leak detection sensor is something that should have been part of the SONOFF ecosystem for a long time. That is a bit late in the game, but it has a unique feature: an Extended Detection Cable that can detect water leaks. Let’s take a look! SONOFF SNZB-05P Water Leak Sensor Unboxing Inside the box, you’ll find the sensor, an Extended Detection Cable (2m), cable clips, and a small manual. The SNZB-05P is water-resistant with an IP67 rating (submersible up to 1 meter for 30 minutes). It uses a CR2477 battery, similar to other SONOFF Zigbee sensors, which should last several years. Both terminals […]

NDAA-compliant NVIDIA Jetson Orin NX and Nano bundles target drones

ARK Electronics has recently introduced NDAA-complaint NVIDIA Jetson Orin NX and Nano bundles designed for drones with the company’s Jetson PAB (Pixhawk Autopilot Bus) carrier board, an ARKV6X flight controller, and an SSD preloaded with NVIDIA Jetpack and the ARK UI. I’ve come across the board following a post on X pointing to an article on Tom’s Hardware about the US passing a bill called “Countering CCP Drones Act” that would effectively ban DJI drones in the US.  DJI is supposed to have a 90% market share of the U.S. hobby market, a 70% market share of the industrial market, and an over 80% market share of the first responder market, so not everybody will be happy if the bill passes in the senate and becomes enacted by the US president. But US companies making NDAA-compliant hardware and drones may bit mind, and that’s how I discovered ARK Electronics NVIDIA […]

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 @ […]

RealTek RTL8126 5Gbps Ethernet PCIe and M.2 adapters are now available for $12 and up

The low-power RealTek RTL8126(-CG) PCIe 3.0 x1 to 5GbE controller was unveiled at Computex 2023 last year, and a few M.2 modules and PCIe cards are now available at very competitive prices. The first module that came to my attention was the “5000Mbps Networking Card B+M Key to PCIe Adapter” from STDEV sold for $27 on Amazon (where there’s also a 7% discount) that’s an M.2 PCIe module with a ribbon cable that is connected to a board with an RJ45 jack attached to a PCIe bracket. There’s limited information about it, and it was just added to Amazon on June 8, so there aren’t any user reviews just yet. But earlier today, Jiri Brejcha informed us he had tested a similar card (might even be the same) from Iocrest with a Raspberry Pi 5 and a Pineboards HatDrive BM1 HAT+ managing to reach 4.7 Gbps transfer speeds in both […]

Serial Bus Servo Driver HAT (A) can drive up to 253 servos simultaneously

Waveshare has recently introduced the Serial Bus Servo Driver HAT (A) ESP32-powered servo motor controller for the Raspberry Pi designed to drive up to 253 serial servos simultaneously. The servos can be controlled via UART or USB through the Pi SBC or used as a standalone controller for a robotics project. The board has a wide input voltage range of 9 to 25 volts and features an onboard XT60 connector, a screw terminal, and a DC barrel jack any of which can be used as power input. Besides that, the board features an RS485 port a TTL Servo header, and a UART control switch for convenience. Previously we have written about the Suptronics X200 HAT multifunction expansion board for the Pi with servo support, as well as the ELECFREAKS Wukong 2040 which can also be used to drive servos.
