3 GND GND GND
4 GND GND
5 GND GND
6 AD7 I 5 input ADCs. 12-bit resolution in case of 3.3V power supply. 0-3.3V input
voltage. Except for AD6, the rest data is sent to OS core via UART3 in
real time with 16KHz sampling rate. AD1 and AD5 can be used in
parallel, and AD3 and AD7 can be used in parallel, which equals to two
32KHz sampling AD. AD1, AD3, AD5, AD7 can be used in parallel, which
equals to a 64KHz sampling AD; the data is summed 1024 times and
then divided by 64 to obtain a 64Hz 16bit AD value by oversampling.

11 +3.3 O 3.3V output, maximum load of 150mA.
12 SPK O External MOSFET to drive buzzer or speaker. The external 10K resistor
should be pulled down to the ground to ensure that power-on is low level.
13 SD_CD IO SD/SDHC interface,The SD_CK connects a 22pF capacitor to GND near
the SD card interface.

19 PWM0 O 2 16-bit PWM output. The external 10K resistor should be pulled down to
the ground to ensure that power-on is low level. The OS core can be controlled in real time via UART3
20 PWM1 O
21 P3.3 IO If using RX8130 or SD2058 I2C RTC to connect to both IOs, SCL should be connected to P3.2,and SDA connected to P3.3 in parallel
with 10K resistor pull-up to 3.3V.
22 P3.2 IO
23 P3.1/EX1 IO It can be used as an external interrupt 1 input at the same time, and
supports both low voltage level or trailing edge interrupt modes.
