MaTouch ESP32-S3 4.2" Triple-Color E-Ink
Our MaTouch ESP32-S3 4.2 Triple-Color E-Ink display is equipped with the SE0420MN11-A0 model, which uses microcapsule electrophoretic technology to show images. This technology works by applying an electric field to charged particles that are suspended in a clear fluid. The particles move to the sides of microcapsules and become visible by reflecting ambient light, similar to traditional printed paper.
The display has an active area of 400 x 300 pixels and full display capabilities of triple color: 1 bit B/W/R. In addition, there are the following advantages：
- The device keeps displaying the last content for an extended period even after power down.
- It consumes ultra-low power and requires power only for refreshing.
- It uses an SPI interface and demands less IO pins, leaving extra pins for I2C and GPIO expansion.
- It supports a 3.7V battery or a 5.0V Type-C power supply.
- The device has two buttons that provide sliding up, sliding down, and pressing functions to enable six interactive points.
- The device features an ESP32S3 controller with WiFi and Bluetooth support.
