- Yes, this is an adorable small HDMI television with incredibly high resolution! We tried to get the smallest possible HDMI display with high-res, high-contrast visibility. The display is very easy to use
- it should be powered by 12DC, then connect a digital video source to one of the ports. It work connect to any device with direct HDMI such as raspberry pi, banana pi and pcduino. The biggest difference is that it can work when you plug it on device without any software support.
- If you want a power adapter : 12V/2A Power Supply
This 7.0" TFT LCD Module can be can be easy controlled by MCU such as 51,AVR,STM32,PIC,MSP430,DSP,ARM, and ARM .It can be used in any embedded systems which require display high quality colorful image. The Module used
SSD1963 LCD controller with 7 inch LCD module with touchscreen. This LCD has a superior display quality and super wide viewing angle, please see the sample pictures, they are taken directly from the LCD display.
On board 400mA DC-DC Boost regulator to provide power supply to LCD backlight
LCD-specificed intialization code is provided, so that you can save time to optimize power control register and gamma curves for best display performance. We have test the provided code, it gives the best display performanace
There’s no doubt Arduino has quickly become the world’s most popular do-it-yourself microcontroller board system, thanks to its simplicity, versatility and surprisingly low cost. But the key to that versatility is its Shield header that allows daughter boards or ‘shields’ to extend the Arduino’s functionality. In the last project, we built a digital clock project using the popular 1602 alphanumeric LCD shield and it’s hopefully had your mind ticking over with other ideas and possibilities. This month, we’re going a step further, introducing a new low-cost shield that incorporates a 320 x 240-pixel TFT LCD touchscreen.
The ST7781 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts,
8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display data RAM of 240x320x18
bits. It can perform display data RAM read/write operation with no external operation clock to minimize power
consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to
Power supply voltage:2.7V-3.3V,5V is OK,but part of the screen becomes black when tested
Data interface level:2.7-5V
Backlight power supply voltage:highest 3.3V
Module size:43.6mm x 43.1mm(width X height)
Installation diameter:2mm
Backlight:White
Features :
84 X 84 dot matrix LCD,can show 4 lines of characters
Use serial interface communicate with the master processor,the number of interface signal line reduced greatly, only 8 signal lines including power and GND.Support different types of MCU,such as the SPI,MCS51 serial mode 0 of AVR.Transfer rate up to 4Mbps,can full speed write display data without waiting time.
Can use the conductive glue to connect the module with the printed board,without connecting cable.The metal hooks on the module can fix the module on the printed board,which is very easy to install and replace.
LCD controller/driver chip has been bound to LCD chip,the volume of LCD is small
Low power supply,the working current in normal situation is lower than 200μA,and has power-down mode
Useful LCD display for Arduino with 16 symbols and 2 lines. Display background LED is connected to potentiometer regulating screen brightness and contrast. You can control switching on/off with sketch.
Display has GREEN color.
LCD display uses standard HD44780-compatible driver. Arduino "LiquidCrystal" library is used for display programming and can be found in Arduino IDE coding environment. You can use standard characters or make your own characters.
LCD display uses digital Arduino digital outputs: 4, 5, 6, 7, 8, 9.
Under LCD there are 5 navigation buttons: Up, Down, Left, Right.
Option. Buttons are connected with A0 analog input only, so you can monitor button status using just one Arduino input. Pay attention: status monitoring is unavailable when several buttons are pressed.
Shield includes blocks of digital and analog inputs/outputs and also it has A1-A5 analog input blocks (5V/GND/IN) for quick connection to periphery.
