• 264KB on-chip SRAM

• 2MB on-board QSPI Flash

• 26 multifunction GPIO pins, including 3 analogue inputs

• 2 × UART, 2 × SPI controllers, 2 × I2C controllers, 16 × PWM channels

• Drag-and-drop programming using mass storage over USB

• Temperature sensor

Raspberry Pi Pico Pinout

Raspberry Pi Pico has a total of 40 input and output pins out of which 26 are multipurpose GPIOs operating at 3.3V and 8 ground pins. Apart from these pins, it also has 3 pins for debugging. The below image taken from the official datasheet of Raspberry Pi Pico illustrates the layout of all the pins.
