The live GPIO pin monitoring library sets up the ESP32 to stream information about what all of the pins are doing in real time to a webserver, which displays the information as a helpful graphic.

If you count in the new ESP32-S3 that brings in USB ... The C3 is really a blend of the two: a limited number of GPIO pins like the ESP8266, but with nice peripherals like the ESP32.

Espressif Systems has just started mass production of the ESP32-C5 RISC-V wireless microcontroller with dual-band (2.4/5 GHz) ...

We made something similar but using the RP2350A board, the Raspberry Pi Pico 2, and published a guide on how to get Wi-Fi on the Pico 2 using an ESP32 ... with more GPIO pins than the RP2350A ...
