​
Power Pins and Connections

  • GND: This is the common ground for all power and logic.
  • USB: This is the positive voltage to/from the USB C jack, if USB is connected (This is usual at voltage 5v).
  • RUN / RESET: This is the run/reset pin of the RP2040, you can pull down this using an external button or other controller to reset the board.
  • 3.3V: These pins are the output from the 3.3V regulator, they can supply up to 800mA peak current.

Communication Pins

I2C, SPI, and UART on RP2040

The RP2040 is capable of handling I2C, SPI, and UART on many pins. However, to simplify things we have assigned few of the IO pins to make things simpler for users.

​
I2C Pins

  • I2C0 SCL: SCL, GPIO9
  • I2C0 SDA: SDA, GPIO8

​
SPI Pins

  • SPI0 SCK : SCK, GPIO2
  • SPI0 MOSI: MO, GPIO3
  • SPI0 MISO: MI, GPIO4
  • SPI0 CS : SS / CS, GPIO5 (or any available GPIO)

​
UART Pins

  • UART0 TX: TX, GPIO0
  • UART0 RX: RX, GPIO1

​
USB Pins

This is used for power and data transfer. Connect to your computer via a USB C cable to update firmware and at the USB pin you would receive 5v.

​
Buttons and Status LED

  • BOOT Button: Hold down during power-on / reset to enter the UF2 bootloader mode (appears as a USB mass storage drive).
  • RESET Button: Restarts the RP2040 microcontroller.
  • Status LED: User-controllable status LED connected to GPIO16.

​
PWM Pins

The RP2040 supports PWM on all GPIO pins. There are 8 dual-channel PWM slices, each with configurable frequency and duty cycle. The important thing to know is that you cannot use the same channel on different pins at the same time. Please refer to RP2040 DATASHEET.

​
Analog Pins

The RP2040 has four 12-bit ADC channels. These pins are the only pins capable of handling analog, and they can also do digital.
  • A0/GPIO26: ADC channel 0
  • A1/GPIO27: ADC channel 1
  • A2/GPIO28: ADC channel 2
  • A3/GPIO29: ADC channel 3
