3.2 inch tft lcd screen module schematice made in china

This module is the 3.2” version of the ESP32 touchscreen display, based on ESP32-WROVER, with a built-in 2M pixel OV2640 camera. The LCD is 320x240 TFT, with driver is ILI9341, it uses SPI for communication with ESP32, the SPI main clock could be up to 60M~80M, make the display smooth enough for videos; and the camera OV2640 with pixel 2M, with this camera, you can make applications such as remote photography, face recognition…

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

ER-OLEDM032-1B is the 256x64 blue pixels OLED display with adaptor board that simplifies your design,diagonal is only 3.2 inch.The controller ic SSD1322, communicates via 6800/8080 8-bit parallel and 3-wire/4-wire serial interface. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast,extremely wide viewing angle and extremely operating temperature.Please refer to below interfacing document for how to switch to different interface. The default interface is 8-bit 8080 parallel.

This is a 3.2 inch TFT touch screen expansion board using standard Shield interface and it has good compatibility. It integrates a 3.2-inch touch screen, I2C temperature sensor, TF card holder, level conversion circuit, and the secondary development is easy.IF with GPRS module, you can design your Arduino phone. IF with NFC reader module, you can create access control systems with the photos show. IF with voltage and current sensor, you can make oscilloscope.

Compatibility: As the SD card is connected to SPI pins of ICSP interface, compatible with UNO R3 / Mega2560 / Leonardo- Touch screen type: resistive touchscreen.

Begin by carefully starting the rear connector of the TFT shield onto the Arduino Uno/Mega. Go slowly and ensure that all pins are inserted correctly and are straight.

In order to use 3.2″ TFT lcd  Shield , We must have the libraries. So you can download  Adafruit-GFX-Library and MCUFRIEND kbv install the library by extracting that zipped file in the library folder as shown below.
