The others 29 pins are dedicated, and they correspond to the ports UART, ADC, PWM, e I2C as we can see in the previous table of the Connector of 40 pins; and to the I2S port as we can be seen in the next that makes reference to the port of 7 pins.
Wengine 29 vigingi ni wakfu, na zinalingana na ya bandari UART PATANIFU, ADC, PWM, e I2C kama tunaweza kuona katika ya awali Jedwali ya ya Kihusishi taswira ya 40 vigingi; na ya I2S bandari kama sisi inaweza kuonekana katika inayofuata ambayo hufanya kumbukumbu ya bandari ya 7 vigingi.
