#M5Paper: a Touch EINK device not only for hobbyist
M5Stack, MicroPython | 2 min | 10786
M5Stack has just launched a new device in its core series. This time, the company has combined two great things into a great product: a 4.7" EINK screen with touch capabilities and an ESP32 with 8MB PSRAM. As usual, the device is compatible with Arduino, MicroPython, and UIFlow. It only costs USD69,00.
The M5Paper is a fully programmable and portable device, which is an ideal choice for an IoT application (or you can just use it as an E-reader). The touch EINK screen can be used to show weather information, control your home application, and so on.
An ESP32-DOWDQ6-V3 (16MB Flash and 8MB PS-RAM) powers the M5Paper. The 4-bit grayscale EINK screen enhances the reading experience. Additionally, the GT911 chip controls the touch screen functionality supporting multipoint touch and a variety of gesture controls.Over the last year, M5Stack has improved the documentation of the products. You can find everything about the M5Paper on this link. Additionally, you can find open-source code examples on GitHub.
Similar to the M5Stack Core Ink, the M5Stack paper is equipped with buttons, sensors, and different ports for Micro-SD card and external devices (HY2.0-4P). Check out Fig. 1!
