## Long description

Gravlaser GRL-21013 is a black-transparent enclosure designed specifically for the Raspberry Pi 4B with support for the Raspberry Pi TV HAT DVB-T tuner. The case provides precise cutouts for USB, Ethernet, HDMI and power connectors, an opening for the GPIO header and space to mount the TV HAT module. Passive ventilation slots are incorporated to help dissipate heat from the Raspberry Pi 4B while preserving a compact and unobtrusive appearance suitable for media or experimental installations.
Advantages
The enclosure allows straightforward installation of the Raspberry Pi TV HAT without modifying the board or tuner, keeping connectors and GPIO accessible. Its black-transparent finish offers visibility of indicator LEDs while maintaining a discreet exterior. Passive ventilation supports stable operation under moderate loads, and the tailored cutouts reduce the need for additional cable routing or adapter accessories.
Suitable for
Home media centers and streaming setups based on Raspberry Pi 4B
Digital TV reception projects using the Raspberry Pi TV HAT DVB-T tuner
Educational and experimental electronics projects that require tuner integration
Compact, fixed installations where port accessibility and passive cooling are required
Key specifications
Material: rigid plastic, black-transparent finish
Compatibility: Raspberry Pi 4B form factor and Raspberry Pi TV HAT DVB-T tuner
Access: cutouts for USB, Ethernet, HDMI, power, and GPIO header
Cooling: passive ventilation slots integrated into the enclosure
Mounting: internal space and screw points for board and TV HAT alignment
How to use
Place the Raspberry Pi 4B into the lower shell of the case aligning board mounting holes with the internal standoffs. Position the Raspberry Pi TV HAT onto the Raspberry Pi’s 40‑pin GPIO header and align its connectors with the case opening before closing the upper shell. Route external cables through the corresponding cutouts for HDMI, Ethernet, USB and power. Ensure ventilation slots remain unobstructed during operation to maintain passive cooling efficiency.
Usage recommendations
Use the case on a flat, stable surface and avoid blocking ventilation openings. For reliable DVB-T reception, connect a suitable antenna to the TV HAT and place the assembled unit in a location with good signal reception. If the Raspberry Pi is expected to run under sustained heavy load, consider monitoring temperatures and, if necessary, supplement with external cooling or relocate to a cooler environment.
