1. Introduction
2, Characteristics
1, digital IO pins (pins from D2 to D13) and analog IO (pins from A0 to A5) pins are provided. (It can meet the need of connecting extension modules with Dupont wires.)
3, there are D0/D1 pin headers that can be used for communication with the outside.
3, Expansion Board Parsing
Digital IO port PH2.0 3P socket (D2-D11) and digital IO port pin header (D2-D13)
You can specify these IO ports as digital outputs, that is, output high level or low level.Among (D2 and D3 pins can be used as hardware interrupt pins.)D3,D5,D6,D9,D10,D11 pins can output analog signals).
Simulated IO port PH2.0 3P socket (A0-A3) and simulated IO port pin header (A0-A5)
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).
