The HMIFeatherWing gives you the possibility to easily add a HMI with a display and a joystick to your project. Just plug it on top of your Feather board and you can implement any HMI or menu structure you want.
The Feather Wing has a EA DOGM132-5 2.1" display (https://www.lcd-module.com/fileadmin/eng/pdf/grafik/dogm132-5e.pdf) with a ST7565 controller and 132 x 32 pixel. The feather wing allows to control the backlight with PWM so you can dimm it and turn it off and on. There exists versions of this display with black or blue color and even a transflective one which even works with or without backlight and is readable in full sun light. You can use any Arduino library for ST7565 controllers or my DogGraphicDisplay library: https://github.com/generati
