Display confirmation
A timing signal from the GERDA to the LCD module may destroy the built-in driver IC of the LCD module depending on its timing. Please pay attention if you are going to control the GERDA directly with jigs. When executing the display test mode with the UART etc., conform to the product movement for the time from the power on to the reset cancellation/communication start, etc.
