The Pi-OLED Hat is a board to easily allow mounting an OLED display onto a Raspberry Pi to display simple status information such as network IP address and player status. It also provides push buttons that are used to access the FPP OLED menu system. From the menus, playlists can be started, various test modes activated, shutdown / restart, tethering options, etc… are available with more to come in future versions of FPP. The hat provides a temperature sensor for reading the current temperature in the mounting location. Finally, the board provides two expansion headers. The first is a 1×4 female header that provides access to the I2C bus for additional I2C peripherals. The second is a 2×5 male header that is a direct mapping to the first 10 pins of the Raspberry Pi connector. It exposes the I2C bus as well as 3 GPIO pins that could be used to wire additional push buttons or other sensors or triggers. Since it is a direct mapping to the Pi header, any of the Pi I2C devices such as RTC's should work.
