Front side has an integrated fan. It is important to have a clear space to allow for air flow circulation in front of this side.

- Mini HDMI input
- Micro SD card slot
- Camera status LEDs

USB A connectors for peripherals connection, for instance:
- 4G / LTE modem
- Rockblock satellite communication system
- FLARM ADSB system


The top side has an a heatsink and mounting holes for an optional fan. It's important to have a clear space to allow for airflow circulation in front of this side.
