IO5

I/O

Used as a GPIO, which is connected to

GPIO_5 (pin 34) on the internal IC

GPIO22

I/O

Used as a GPIO, which is connected to

GPIO_22 (pin 39) on the internal IC

RXD

I/O

UART0_RXD (See the following Note 3.)

TXD

Output

UART0_TXD (See the following Note 3.)

Note:

1. P indicates power supply pins, I/O indicates input/output pins, and AI indicates analog

input pins.

2. This pin can only function as an ADC input and not a common I/O. If this pin is not

used, it must be disconnected. When this pin is used as the ADC input, the input

voltage range is 0 V to 3.3 V.

3. UART0 is a user-side serial interface, which generates information when the module

is powered on and starts.
