This is a case for a diy portable FM radio. It uses a TEA5767 stereo radio receiver module with two headphone jacks, one for the antenna and one for the speaker. It runs on an esp32 dev module, it has an LCD screen to see the channels and frequency, it has a 5 pin potentiometer to navigate in the menu and different modes, it has an 18650 lithium cell with a recharge board and a buck converter to convert the 3.7 volt from the battery to 5v for the esp vin and the TEA5767 and it has a power switch. The antenna is on the side and plugs in via the headphone jack already installed on the TEA5767 and when not in use or in storage for traveling, the antenna can be put on top in the dedicated slot. There is no need for screws for the case as this is a snap fit design.
