Year 2025 in Review, CNX Software stats, and looking ahead to 2026

Time for the last post of 2025, as the year is almost over. I’ll look back at key developments and notable products launched in 2025, share some CNX Software website traffic statistics, and look ahead to 2026. Year 2025 in Review After 22 product releases in 2024, Raspberry Pi calmed down a little bit in 2025, and the highlights of the year included the Raspberry Pi 500+ mechanical keyboard, the 5-inch variant of the Raspberry Pi Touch Display 2, and a Raspberry Pi 5 1GB RAM. What didn’t quite stop were the accessories from third parties for Raspberry Pi SBC and Raspberry Pi Pico boards. The most exciting Arm SoC release of 2025 was probably the 12-core CIX P1 Armv9 SoC found in Radxa Orion O6 SBC, MINISFORUM MS-R1 Arm mini PC, and Orange Pi 6 Plus board, but while performance was fine, it was overhyped in 2024, and software […]

DFRobot HUSKYLENS 2 AI camera review – From built-in AI samples to training a custom model to detect elephants

Hello, today I am going to review the HUSKYLENS 2, released in October 2025. It is the next generation of HUSKYLENS, an AI vision sensor equipped with a Kendryte K230 dual-core RISC-V SoC with a 6 TOPS AI accelerator and a 2.4-inch IPS touchscreen. The device runs machine vision algorithms fully on-device, providing fast and low-latency performance, and includes more than 15 built-in AI models. HUSKYLENS 2 also supports deploying custom-trained models, including integration with Large Language Models (LLMs) via a Model Context Protocol (MCP) service. In addition, it is compatible with various microcontrollers, such as Arduino and Raspberry Pi, through UART or I2C communication interfaces. HUSKYLENS 2 unboxing The manufacturer sent the HUSKYLENS 2 module and the Microscope Lens separately. Both parcels were shipped from Chengdu, China, and arrived at my office in Chanthaburi, Thailand, in about one week. The parcels were packed in standard cardboard boxes and arrived […]
