FPV Analog Signal Video Descrambler Encryption Module Hardware 3.3V Customized

• CVBS video stream scrambling and descrambling module used in pairs (transmitter and receiver)
• FPGA digital encryption with high-intensity 32-bit password (up to 2³² combinations)
• Supports PAL and NTSC analog video stream encryption/decryption
• DIP switch configurable for scrambling or descrambling operation
• Password configuration via serial port interface
• Compatible with all FPV VTX systems
• Enhances FPV video security and privacy

The module collects CVBS video and performs analog-to-digital conversion. The digital signal is encrypted through FPGA, reprocesses the video image, then undergoes digital-to-analog conversion to output standard CVBS format to the transmitter.

The received CVBS video signal undergoes analog-to-digital conversion, is decrypted through FPGA, reprocesses the video image, then converts back to analog format for display on the screen.

Module dimensions: 34.5*34.5mm. Top height ≤3mm, bottom height ≤1mm, board thickness 1.2mm. Four corner mounting holes (2.5mm diameter). Weight: 4.3 grams.

Sets module operation mode: "ON" position (left) for encryption, "I" position (right) for decryption.

TTL 3.3V interface for password configuration via AT commands. Fixed baud rate: 115200, 8 data bits, 1 stop bit, no parity. Includes 3.3V power pin (max 500mA).
