 The AI-deck can be mounted both on top and on the bottom using the provided long header pins. Either position might yield different pros & cons but for development when a JTAG cable needs to be attached the top position works best. Note though that the ESP32 antenna is a bit fragile and can be damaged during crashes. For better resilience during crashes, mount the AI-deck at the bottom, or put a peace of hot-glue as shown in the picture below.
