The most obvious feature of the Pico Pro is the RJ45 network connector, taking up roughly a quarter of the total board space on what is rather a small PCB. At roughly 75mm x 25mm (3″ X 1″), that board packs quite a few surprises into a very limited space. The first is t...

Therefore these phases need a quarter the clock cycles compared to standard SPI. In terms of performance: QIO > QOUT >> DIO > DOUT. QOUT or QIO are much faster than DIO or DOUT. ESP Easy official builds uses DIO for everything except DOUT for the smaller (1M size) units. ...

ESP32-Touch, Hall, I2C, PWM, ADC, & DAC: The ESP32s, are a series of inexpensive microcontrollers introduced in the last quarter of 2016. They are powerful systems on a chip (SoC), they replace the ESP8266, and perhaps one might even say the Arduino UNO.
