Can 6-9, 12, and 13 pins be used as GPIO for pin assignment on the main board of the spresense?

Asked 2 years ago, Updated 2 years ago, 125 views

Looking at the SPRESENSE specification, it is divided into three parts:

  • CXD5602 pin name
  • Ardirno pin name
  • Functoin pin name

I need two UARTs and six GPIOs for an external connection, and one of the UARTs uses the micro USB of the main board CN2, and I would like to connect to the other one from GPIO.In this case, we would like to use 6-9 pins and 12 and 13 as GPIO using UART communication on 2-3 pins.

The CXD5602 pin name says 6-9, 12, and 13 pins are I2S, SPI and IRQ, but is it possible to use this as just a GPIO?

Assuming that the 2-13 pins are the pins shown in the figure below, you can use 2-3 pins (D01, D00) as UART while 6-9, 12 pins as GPIO (D26, D25, D24, D23, D22).However, the 13-pin is an analog input (A2) and cannot be used as a GPIO.
