This enclosure snugly encases a Raspberry Pi 3A+. Apply some force and finesse to insert the board into the top part of the case. Begin by guiding the connectors on the side (audio jack, HDMI port, and micro-USB port) into their respective cutouts, and then carefully maneuver the board so that the USB-A port aligns with its designated opening. The top part will securely hold the Pi in place, after which it can be placed onto the bottom part. Depending on the use case, the connection between the two parts might not be stable enough, so it might be worth considering gluing both enclosure parts together.
