Mini DVR is a compact module for recording analog video onto a microSD card. DVRs are commonly integrated into FPV goggles, but if your goggles do not have one, you can easily add it by using this external module. The DVR module features a built-in battery that can be recharged via a USB-C connector. Both video input and output are provided through a 4-pin jack connector. The video output allows for live preview and playback of recorded footage. The DVR supports microSD cards up to 32GB, formatted in FAT32.
