External Interface
Pin | Definition | I/O | Functional Description |
1 | +5V | I | Power supply, DC3.6-5.5V |
2 | +5V | I | |
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. |
7 | AD6 | I | |
8 | AD5 | I | |
9 | AD3 | I | |
10 | AD2 | I | |
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 |
13 | SD_CD | I/O | SD/SDHC interface,The SD_CK connects a 22pF capacitor to GND near the SD card interface. |
14 | SD_CK | O | |
15 | SD_D3 | I/O | |
16 | SD_D2 | I/O | |
17 | SD_D1 | I/O | |
18 | SD_D0 | I/O | |
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 | I/O | 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 | I/O | |
23 | P3.1/EX1 | I/O | 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. |
24 | P3.0/EX0 | I/O | It can be used as an external interrupt 0 input at the same time, and supports both low voltage level or trailing edge interrupt modes. |
