FC for Fame Console Video Expansion Board AV+RF Output DC-DC Step-Down Games Accessories

Adopts DC DC step-down technology for efficient power conversion.

Incorporates LC filtering for very small ripple and minimal heat generation.

Supports a power supply range of 9~18 volts, compatible with both positive and negative inputs.

Utilizes a dedicated IC for RF output, ensuring stable operation and clear image quality.

The design allows for two-channel selection via jumper settings, and includes options for two-way audio output while sacrificing TV functionality.

After many revisions, this version has become perfect. The power sw on the board can be connected to a self-locking switch to control the power supply of the whole machine. If there is a switch on the motherboard, short-circuit the Power sw, otherwise it will not be powered. The R21 zero-ohm resistor on the board can be unsoldered to the R2 position to achieve two-way audio output, and the other output is from the RF socket. Although it is connected in parallel, it is better than one speaker.
