SKU:K159
Description
PaperDIY Assembly Kit is a DIY e-paper development board kit that includes a main control board, an e-paper display, and a 140mAh lithium battery, with hardware assembly completed by the user. The main control board uses the ESP32-S3R8 core, featuring a standard 16MB Flash + 8MB PSRAM memory combination and supporting 2.4 GHz Wi-Fi connectivity. The kit is equipped with a 4.7" e-paper display with a resolution of 960×540, supporting 16-level grayscale display. It has an onboard battery connector, a microSD card slot, and a USB Type-C interface. The open structure allows users to design their own peripheral structures, making it suitable for building desktop information displays, electronic labels, maker DIY projects, and embedded hardware development experiments.
