1. Introduction
HS-UNO-EXA2(Expansion Board) is a้ ๅฅ expansion board designed for the development board Arduino Uno, integrating the pins of the development board onto a single PCB circuit board.This expansion board is compatible with all HELLO STEM UNO series development boards.The PCB has a PH2.0 interface while also retaining a pin header to meet the different wiring needs of users.It can achieve convenient wiring at the same time, and it also allows users to flexibly add and remove external expansion modules.
2, Characteristics
1. There is a digital IO pin header (pin numbers from D8 to D12), a simulation IO pin header (pin numbers from A2 to A3), and a serial communication pin header interface P6. (It can meet the requirements for using Dupont wires to plug in expansion modules)
2, there are 4 digital IO ports with PH2.0 3P sockets (D3, D9, D10, D12) and 2 analog IO ports with PH2.0 3P sockets (A2, A3), as well as 4 PH2.0 4P sockets and 2 PH2.0 5P sockets.
3, a button connected to the D2 pin of the development board
3, Expansion Board Parsing
Digital IO port PH2.0 3P socket (D3, D9, D10, D12) and digital IO port pin (D9-D12)
You can specify these IO ports as digital outputs, that is, output high or low levels. The D3 pin can be used as a hardware interrupt pin. The D3 and D10 pins can output analog signals.
Simulated IO port PH2.0 3P socket (A2-A3) and simulated IO port pin (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).
