RDA5807FP Card Radio - VERITAS

This mini card radio, based on the RD5807FP, has undergone peripheral optimization and can receive FM frequencies using headphones as an antenna. The direct output sound is still quite pure.

This project is a simple RDA58087FP card radio, powered by CR2032 batteries and using an earphone cable as the antenna. It provides basic FM radio functionality.

I've also added a small custom design element: a small acrylic radio keychain combining a blue-architectural Beritas-style back panel and front panel. No programming is required; simple soldering is all it takes. It's suitable for beginners practicing soldering.
Instructions: Insert the batteries and earphones, turn it on, and press seek+ or seek- to automatically search for stations. It will stop when a station is found.

Points to note: 1. It's best to use CR2032 batteries. Rechargeable batteries like LI2032 may have issues with insufficient voltage or short battery life.
2. The front panel printing thickness is 1.5mm. It's best to print from the bottom; the logo will have a glowing effect under side lighting. Thanks to LCSC for their efficient and high-quality front panel printing.
3. Saving the project may revert to the default font. Include a Gerber file in the attachment; you can edit the project with your preferred image. 4.
Hardware includes four M2x9 hex socket screws and four M2 lock nuts.
5. Custom LCSC panel is used; the file is in the project file at the bottom.
To be added.
