If you buy this kit as a separate case for your ATU-100, it will come without instructions. I wrote to the seller and he sent them to me straight away. The circuit board terminates near the two end plates of the case, allowing the OLED to be installed connector-up only. This caused the display to tip over. This is not a problem for me as I have a PICKIT3 programmer and edited the firmware to flip the display. The product appears to be of good quality and works as advertised after you edit the firmware.
