Night Vision Analog FPV Headset

The night vision headset is designed around the Tang Primer 25k FPGA to deliver maximum 549us of latency @60Hz night vision feed with thermal outline overlays. Additionally, the headset has an additional port to adapt any analog drone FPV receiver, creating a dynamic, low latency, utility headset for law enforcement, private security, inspection, and recreational use.

Version 1:

Prototype versions testing the IR camera input and display output

Second prototype focusing on ESP32 functions in combination with FPGA timing for display and camera feed

Reverse Engineering SONLC-02A FLCOS Displays

Starting with the displays, I found these "0.2in FLCOS micro displays" from Aliexpress which use a driver board to convert CVBS into display data. For this project, I only needed the displays as they were, in theory, compatible with my FPGA. I reverse engineered their input, the I2C initialization data, and their power-on sequence, all without a datasheet, pinout table, or examples. The result is a VGA micro display which i can run entirely from 21 pins on my FPGA.
