ADC pin (See the following Note 2.)
9
IO24
I/O
GPIO_24, a standard PWM pin, which is
connected to GPIO24 (pin 32) on the IC
10
RST
I/O
Hardware reset pin (active at a low level)
11
IO3
I/O
GPIO_3, a standard PWM pin, which is
connected to GPIO3 (pin 23) on the IC
Note:
1.
P
indicates power supply pins,
I/O
indicates input/output pins, and
AI
indicates analog
input pins.
RST is only a hardware reset pin and cannot clear the Wi-Fi network configuration.
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 2.0 V.
3. The UART pins are user-side serial interfaces.
