1. Introduction
The EX-U+AL2(expansion board) is a้ ๅฅ expansion board designed for the development board U+ PROGRAM CARD, integrating the pins of the development board on a PCB circuit board.The circuit board has both pin header interfaces and also retains the PH2.0 interface.2 types of interfaces, meeting the different wiring needs of users.Can allow users to flexibly add and remove external expansion modules.Adapter power interface: DC005/5.5-2.1MM.Supply interface input voltage range: 6-12V.Board power module output power: 5V/2A.I/O interface: 2.54 pin interface, 2.54 socket size: 65 mm*45 mm*19 mm.
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 (pins from D2-D11) and analog IO ports PH2.0 3P sockets (pins from A0-A5) as well as 4 PH2.0 4P sockets, 2 PH2.0 5P sockets, and 1 PH2.0 6P socket.
3, There is 1 power interface for adapter power supply.
3, Expansion Board Parsing
Digital IO pin (D2-D13) and Digital IO PH2.0 3P socket (D2-D11)
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.
Simulation IO pin (A0-A5) and Simulation IO pin PH2.0 3P socket (A0-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).
Adapter power supply interface
DC005/5.5-2.1MM. Power supply interface input voltage range: 6-12V.
