Getting Started

Here is an example of using 2.13-inch eInk and a XIAO ESP32S3, If you're want to work with other eInk of different sizes, please check the supported eInk table above, you could also find the demo code specific to those on their respective example code folder.

STEP 1: Insert the XIAO ESP32S3 into the XIAO Socket: Align the pins and gently insert your XIAO ESP32S3 into the XIAO socket on the board.

STEP 2: Insert the eInk into the FPC Connector: Carefully slide your 2.13-inch ePaper into the 24-pin FPC connector on the ePaper Breakout Board.

STEP 3: Download the Demo Code: Navigate to the demo code repository and open the code for your specific eInk Screen and use Arduino IDE to flash onto your XIAO ESP32S3. Follow the instructions in the repository to upload the code.

STEP 3-1: Once you have downloaded and unziped the demo code, please navigate and open the "2.9 inch E-paper - Monocolor 128x296" folder.

STEP 3-2: Then open the "example" folder:

STEP 3-3: Then use Arduino to open the "example.ino" file:

STEP 3-4: Please click the Board selection dropdown menu, and then click on "Select other board and port..."
