1. Introduction
2, Characteristics
2, there are 2 PH2.0 3P sockets and 2 4P PH2.0 sockets, as well as 2 PH2.0 4P sockets.
3, Expansion Board Parsing
Digital IO pin (D2-D13)
You can specify these IO ports as digital outputs, that is, output high level or low level.The D3 pin can be used as a hardware interrupt pin.D3, D10, D11 pins can output analog signals.
Simulated IO port PH2.0 3P socket (A0, A1) and simulated IO port pin header (A2-A3)
You can specify these IO ports for simulated input and simulated input. The simulated input returns a value of (0-1023). The simulated output value is (0-255).
G/V/A4(SDA)/A5(SCL) socket
This socket is convenient for mating with some modules that use a PH2.0 4P interface. (Compatible module: HS-S63-L)TCS342 color sensor, HS-F14LTM1650 four-digit LED digital tube module, HS-F15LTM637 four-digit clock digital tube module, HS-F19LOLED display, HS-F21LLCD1602 display, )
GND/A1/A0/VCC socket
The socket is convenient for connecting with some modules that use a PH2.0 4P interface. (Compatible module: HS-SR04L)Ultrasonic Sensor)
VCC/GND/RX(D0)/TX(D1) 4P pin header
This pin header interface is for the development board's serial communication interface.
