Ameba RTL8722DM is a low-power dual-band WLAN and Bluetooth Low Energy SoC by Realtek. The RTL8722DM also include memory for Wi-Fi protocol functions and application making it simple for anyone to develop various kind of IoT applications. At the same time it has a wide range of peripheral interfaces. With all these interfaces, it can connect to most of the electronics components like LEDs, temperature and humidity sensors, and so on.
The e-Paper module display uses the flexible substrate as a base plate, with an interface and a reference system design. The 2.9" active area contains 296x128 pixels and has 1-bit white/black full display capabilities. An integrated circuit contains gate buffer, source buffer, interface, timing control logic, oscillator, etc... are supplied with each panel. You may refer to the official 2.9inch e-Paper HAT (D) datasheet to know more information about this module.
