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

Happy New Year 2026 CNX Software

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 […]

MicroPython v1.27 adds support for ESP32-C5, ESP32-P4, and STM32U5 microcontrollers

MicroPython v1.27

MicroPython is one of the most popular firmware for microcontrollers due to its ease of use. The MicroPython v1.27 release adds support for some interesting microcontrollers, namely Espressif Systems ESP32-C5 and ESP32-P4, thanks to an update to the ESP-IDF v5.5.1 framework, as well as STMicroelectronics STM32U5, and features a range of other changes. These include improvements to the test suite to cater to the increasing number of supported hardware platforms, the introduction of tier levels for different hardware platforms, various optimizations and bug fixes, updated libraries, new ESP32 and STM32 boards, and more. The last time we reported on a MicroPython release was for v1.24, which added support for Raspberry Pi RP2350 and ESP32-C6 microcontrollers.   Other MicroPython v1.27 highlights: Test suite improvements Auto-detecting if the target has Unicode support Automatically including float tests when possible Always including stress tests Improving the skipping of tests that use slice and the […]

Arduino-programmable environmental and air quality sensor kit features ENS160 and BME280 sensors

Novaduino Environmental Sensor Kit

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display Module. It provides VOCs, eCO₂, temperature, humidity, and barometric pressure data in real time, making it ideal for Smart Home experiments, classroom projects, or hobby weather-station builds. The kit integrates a Sciosense ENS160 air-quality sensor and Bosch BME280 environmental sensor connected via Qwiic, which measures TVOCs, eCO₂, temperature, humidity, and pressure with an on-device AQI indicator. It includes the Novaduino display PCBA, 2.4-inch IPS touchscreen, buttons, rotary encoder, Feather M0 Express or RP2040 module support, headers, mechanical hardware, and optional 3D-printable enclosures (STL/F3D/STP).  Designed for learning soldering, assembly, and Arduino programming, the kit is uncalibrated and intended for educational and experimental use only.

Black Friday and Cyber Monday 2025 – International deals, coupons, and events

AliExpress Black Friday 2025

Like every year since 2014, I’ll list a few international deals for Black Friday and Cyber Monday 2025, as many CNX Software readers cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events, which will take place from November 20 to December 1. I’ve gathered various deals, discount coupon codes, and events from relevant manufacturers of single board computers, MCU development boards, mini PCs, Smart Home devices, and DIY products, as well as popular online stores, including AliExpress, Banggood, and others. AliExpress Black Friday and Cyber Monday 2025 event AliExpress sales event for Black Friday and Cyber Monday 2025 has just started and will last until December 3, 2025 (although I can see until November 29 and December 4 in some places). You can use some of the coupons on the screenshot above, or some alternative coupon codes for the US and some other countries (excluding DE, RU, […]

HackStar – An RP2040 or ESP32-S3-based USB hacking cable/dongle (Crowdfunding)

HackStar

HackStar is an ethical hacking tool based on Raspberry Pi RP2040 or ESP32-S3 in a USB cable or dongle form factor for education, pentesters, and makers. While the email I received claimed the HackStar was the “first-ever production-ready ethical hacking product on Kickstarter”, we’ve written about a range of hacking devices based on ESP8266, ESP32, and/or RP2040 microcontroller(s) such as the popular Flipper Zero, the BUG USB stick, nRFBOX V2 ESP32 wireless hacking tool, ESP32 Marauder Double Barrel, HackyPi USB adapter, and many others. What’s relatively new, or at least less common (see HackCable project), here is that the HackStar is also available as a USB Type-A to USB Type-C WiFi hacking cable… HackStar Cable hardware specifications: Wireless SoC – Espressif Systems ESP32-S3 dual-core LX7 processor @ 240 MHz with 2.4 GHz WiFi 4 and Bluetooth LE/dual mode USB Type-A male connector USB Type-C male connector Length – TBD HackStar […]
