AITRIP 10PCS PCF8574 PCF8574T IO Expansion Board I/O Expander I2C Evaluation Develop Module

The PCF8574 IO Expansion Board provides general-purpose remote I O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)..
The main resources: PCF8574, I2C interface, the 8-bit parallel.
Typical applications: for I / O resource constraints the MCU I / O expansion.
PCF8574T expansion board applicable to a variety of platforms including AVR / ARM.
PCF8574T PCF8574 IO expansion board support I2C bus cascade (by pin header row seat docking methods can be used simultaneously multiple I2C modules).

With PCB board (including power supply IC, touch IC, SD cardcage) compatible 5110 interface.
At least 4 IO driver are needed (without touch) , at least 9 IO driver are needed( with touch).
This 2.8-inch LCD module uses ILI9341 drive chip to drive 240*320 dot , with 240*320 resolution.
The module is equipped with voltage stabilized IC to support 3.2v /5V power supply.
2.8 inch color screen, support 65K color display, and the display is colorful.

Using IO trigger for at least 10us high level signal.
The module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
If the signal back, through high level ,time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level....
Power supply :5V DC, quiescent current : .

【Same function as the original Arduino】It great for learning the basics of how sensors and actuators work, and an essential tool for your rapid prototyping needs.
【CHIP UPGRADE】Upgrade the main control chip to ATMEGA328P-AU.And it same as the original arduino pin layout. It compatible with all expansion boards..
【ADDED A 500MA SELF-RECOVERYFUSE】Compared with the original ARDUINO, a 500ma self-recovery fuse is added, which automatically disconnects the circuit when short-circuited to avoid component damage.Change the plug-in pins of the original ARDUINO to SMD pins to avoid short circuit of the development board contact conductors, which is safer..
【Added 10 LED marquees driven by MOS tubes】which avoids the problem of insufficient output current of the IO port of the single-chip microcomputer, and can directly drive a small DC motor through the IO port..
【EASY TO USE】Change the original USB-B type interface to MICRO-USB interface, which is more convenient to use..

BRIGHT AND CLEAR DISPLAY: Blue back light and white char color, adjustable contrast..
NOTE: Built with arduino IIC bus control, which takes only two IO ports(the original 2004 LCD needs 7 IO ports to be up and running).
ADJUSTABLE: Screen display contrast is adjustable by adjusting the screw of blue part.
EASY OPERATION: Screen display contrast is adjustable by adjusting the screw of blue part..
BACKLIGHT: Backlight could be controlled through jumper wire or through program..

3D Printer Accessories Set meets most needs. Including CNC Shield V3.0, UNO R3 Board, A4988 StepStick Stepper Motor Module..
