A Chip Is Born: RP2040-Based Boards Go From 0 to 60+ With Impressive Speed

The microcontroller market โ€” where chips designed for real-time embedded use are placed into development boards typically referred to as “microcontrollers” themselves โ€” is rarely shaken up. If you want something friendly to beginners, you pick an Arduino with a Microchip ATmega328; if you want connectivity, an Espressif ESP32-based board; for performance, STMicro’s STM32 series. […]

I wished that I would begin seeing more such displays in places like restaurants and shops, not to mention school classrooms, offices and makerspaces in the coming months. In Carterโ€™s Adafruit project, the CO2 monitoring device presents a concise public-health message.
