ESP32 0.96 Inch OLED Wifi And Bluetooth Module

OLED is a graphical display module that can be used to display small images and graphics and we already interfaced with ESP32 to build an Internet Clock. It is a small and less power-hungry module.

OLED (Organic Light Emitting Diode) is a kind of Light Emitting Diode that is made using organic compounds that excites when electric current allowed to flow through them. These organic compounds have their own light hence they don’t require any backlight circuitry like normal LCDs. Because of this reason OLED display technology is power efficient and widely used in Televisions and other display products.

ESP32 has integrated antenna and RF balun, power amplifier, low noise amplifier, filter and power management module. The whole solution is that the PCB area is small. This committee is 2.4 GHz dual-mode Wi-Fi and Bluetooth low energy technology, composed of TSMC 40nm chips, power and excellent radio frequency characteristics, with a wide range of applications that are safe, reliable and scalable.

This product is a Wemos 0.96inch OLED integrated with ESP32 chip and can connect to bluetooth.
