CNX Software ☛ Phyx LANA-TNY – A WCH CH32V203 RISC-V development board for embedded applications
The LANA-TNY is a compact development board created by Phyx and built around the CH32V203 RISC-V microcontroller. It offers a low-cost solution for embedded development and features a built-in USB bootloader, eliminating the need for an external programmer to flash the firmware. With a USB-C connector and a minimalist design, the board provides essential components to start development quickly. At its core, the Phyx LANA-TNY is powered by the CH32V203G6U6, a 32-bit RISC-V microcontroller from WCH Electronics, capable of running up to 144MHz with 1-cycle multiply/divide operations.

CNX Software ☛ Infineon PASCO2V15 CO2 sensor achieves ±50 ppm accuracy with built-in microphone and IR emitter
Infineon’s PASCO2V15 CO2 sensor is a compact and precise carbon dioxide sensor that uses photoacoustic spectroscopy (PAS) leveraging its built-in microphone and IR emitter to detect CO2 levels by measuring pressure changes caused by the absorption of infrared light by CO2 molecules. The sensor is highly precise (±50 ppm ±5%) and can cover a wide range (0 to 32,000 ppm).
