The ESP32 chip features 34 physical GPIO pins (GPIO0 ~ GPIO19, GPIO21 ~ GPIO23, GPIO25 ~ GPIO27, and GPIO32 ~ GPIO39). Each pin can be used as a general-purpose I/O, or be connected to an internal peripheral signal. Through IO MUX, RTC IO MUX and the GPIO matrix, peripheral input signals can be from any IO pins, and …

WebSep 23, 2014 · GPIO: Stands for "General Purpose Input/Output." GPIO is a type of pin found on an integrated circuit that does not have a specific function. While most pins … WebDirectly manageable by a single transistor driven by a GPIO pin, and a resistor per led, so the circuit to build is very simple. With a reduced amount of standard LEDs, you can use the same RPi power source (count some 30mA per LED if using a 330 Ω resistors, so you need some additional 120mA).
