Keyes 2.13 Inch 250*122 E-Ink Dispaly Screen LCD Module Black &White color

Introduction:
When doing DIY experiments, we often need to use the display. The Keyestudio electronic ink screen module has a 2.13-inch display with a black and white color and a resolution of 250*122. The module dynamically displays the pattern via SPI communication. There are 2 slide switches on the back. The P1 slide switch is for adjusting the display brightness. Sliding to a??0.47a?? position, the display is brighter; sliding to a??3a?? position, the display is darker. The P2 DIP switch is used to adjust the power supply voltage. Sliding toa??5VINa?? position, the power supply voltage is 5V; sliding to a??3.3VINa??, the power supply voltage is 3.3V. The module comes with two positioning holes with a diameter of 3mm, easy to fix it on other devices . For your convenience, we also provide detailed methods for using the display module and the microcontroller. Special Note: When testing, we use the IDE software 1.8.9 version; if you use other versions of the IDE, source code may be incompatible.
