LinkStar H28K is a compact travel router with dual gigabit Ethernet based on Rockchip RK3528 SoC

LinkStar H28K Compact Quad Core Travel Router

The LinkStar H28K is a compact travel router equipped with a Rockchip RK3528 processor. It offers two Gigabit Ethernet ports and comes with 4GB of memory and 8GB of eMMC storage, which can be expanded to 512GB using a microSD card. Additionally, it features a 12V Type-C connector with Power Delivery (PD) capability. Sadly this router does not offer Wi-Fi capabilities, but the LinkStar H68K does. We’ve also looked at other small yet powerful routers like the NanoPi R5S, FastRhino R68s, and the Radxa E25.  Additionally, we’ve written about the X88Pro 13 8K TV box built around the same RK3528 SoC as found in the H28K router.

$16 Grove Vision AI V2 module features WiseEye2 HX6538 Arm Cortex-M55 & Ethos-U55 AI microcontroller

Grove Vision AI V2 XIAO ESP32-C3 OV5647 camera

Seeed Studio’s Grove Vision AI V2 module is based on the HiMax WiseEye2 HX6538 dual-core Cortex-M55 AI microcontroller with an Arm Ethos-U55 microNPU and features a MIPI CSI connector for an OV5647 camera. It is designed for AI computer vision applications using TensorFlow and PyTorch frameworks and connects to hosts such as Raspberry Pi SBCs, ESP32 IoT boards, Arduino, and other maker boards over I2C. We tested the previous generation Grove Vision AI module based on the 400 MHz HX6537-A DSP-based AI accelerator using the SenseCAP K1100 sensor prototype kit with LoRaWAN connectivity, and managed to have the kit perform face detection and send the data over LoRaWAN. The Grove Vision AI V2 builds on that but with a modern Arm MCU core and more powerful AI accelerator that can run models such as Mobilenet V1/V2, Efficientnet-lite, and Yolo v5 & v8 using the SenseCraft low-code/no-code platform. Grove Vision AI […]

Seeed Studio mmWave sensor kit – Part 1: unboxing and first impression with ESPHome and Home Assistant

mmWave Human Detection Sensor Kit Review Home Assistant

Excited to share my first review, written for CNX Software! This time, we’re diving into the Seeed Studio mmWave Human Detection Sensor Kit, which harnesses the power of mmWave radar. The technology I’m particularly interested in for its smart home potential. Therefore, I jumped at the chance when CNX Software offered a product review opportunity. The kit arrived promptly at my doorstep just one week after accepting CNX Software’s offer. Here are my initial findings of the product and its capabilities to replace existing motion detection products.  Unboxing the mmWave sensor kit I opened the DHL box and found the neatly bubble-wrapped mmWave Human Detection Sensor Kit. Alongside the kit, I discovered a bonus: the MR60FDA1 60GHz mmWave Sensor – Fall Detection Module Pro. This higher-frequency module boasts better resolution and even adds a fall detection feature compared to the kit’s included module, the MR24HPC1. However, the MR24HPC1 24GHz mmWave Sensor […]
