This integration includes a 40 MHz crystal oscillator, 4 MB of flash memory, filter capacitors, and an RF matching network, components that would typically require separate installation. This streamlined approach not only simplifies the setup but also enhances the module’s overall efficiency and functionality.

All the pins of the ESP32-PICO-V3 are connected to the pin headers, offering compatibility with various interfaces such as PWM, ADC, DAC, I2C, I2S, and SPI.
