1. Introduction
HS-UNO-EXP1 (expansion board) is a matching expansion board designed based on the Arduino Uno development board, integrating the pins of the development board onto a PCB circuit board.This expansion board is compatible with all the HELLO STEM UNO series development boards.The circuit board has a PH2.0 interface and also retains a pin header, meeting the different wiring needs of users.Can achieve wiring convenience at the same time, and also allows users to flexibly add and remove external expansion modules.
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.)
2, there are digital IO ports PH2.0 3P sockets (pin numbers from D2 to D11) and analog IO ports PH2.0 3P sockets (pin numbers from A0 to A3) as well as 4 PH2.0 4P sockets, 2 PH2.0 5P sockets, and 1 PH2.0 6P socket.
3, It has a 3.3V power pin that can be used for modules with small external current requirements.
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).
