Materials
  • Ameba x 1
  • Waveshare 2.9inch e-Paper HAT (D) x 1
Example
In this example, we use the Ameba RTL8722 module connects to a Waveshare 2.9inch e-Paper module to display a texts in alphanumeric. The display uses the flexible substrate as the base plate, with interface and a reference system design. The 2.9” active area contains 296×128 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 about this module.
