The gray lora antenna is small, so it can be put into the white lora case. But other big 915 antennas can not be used with lora board when lora case installed. ^^ The lora case has a strict requirement in size of lora antenna fitting with it. It means not all antennas working with it. ^^ This 915MHz LoRa board comes unassembled, soldering is required for you, not equipped with lithium battery. ^^ When you use this 915MHz oled wifi lora 32 board, you need to use 2pcs together, one for receiving data and another sending.
^^ - 0.96 oled is mounted on esp32 lora board via 4 screws, so it is removable but pls be careful to do it to avoid damage. ^^ You will receive 2pcs 915MHz esp32 lora board V3, 2pcs lora case for it, 2pcs lora antenna 915mhz, and 2pcs 1.25 mm connector cable.
