Orange FM

Orange FM is a cartridge for Game Boy that allows you to listen to FM radio stations through your Game Boy’s speakers (on certain models, see compatibility chart below). It features an internal antenna for strong signals, as well as support for external antennas connected to the cart’s audio jack. In addition to mono audio output through the console, the cart delivers stereo audio through the cart’s audio jack to connected headphones or speakers. Learn more about Orange FM

Assembled PCB
If you order the assembled PCB, you’ll receive:

• A fully assembled Orange FM circuit board, no soldering required
• An Orange FM cart label (non-holographic)

To complete this project, you will need:

• A cartridge shell. We recommend a GBC style shell. You can use a DMG style shell as well, but trimming the shell to fit the headphone jack is more difficult. Trimming/filing of the shell is required for the PCB to fit, due to the audio/antenna jack. A 3d printed cutting guide is available as an optional purchase, or you can print your own.

DIY PCB
If you order the DIY option you will receive:

• An Orange FM circuit board, with a pre-soldered and pre-flashed MCU containing the Orange FM firmware. A few other supporting parts are also pre-soldered.
• An Orange FM cart label (non-holographic)

To complete this project, you will need to have:

• The remaining parts. See the DIY assembly guide here, which includes the BOM, a basic assembly guide, and links to pre-made shopping lists for both Digikey and Mouser. Make sure you can source the flash chip SST39SF010A or SST39SF020A or SST39SF040 as it is EOL. 
• The ability to solder QFN, small pitch TSOP packages, and 0603 sized components. The radio chip is a small QFN package, and you will need a hot plate, hot air, or reflow oven to solder it. The other parts can be soldered with a regular soldering iron.
• A GBxCart or similar to flash the ROM file. This will also allow you to apply any updates that are released to the Orange FM ROM.
• A cartridge shell. We recommend a GBC style shell. You can use a DMG style shell as well, but trimming the shell to fit the headphone jack is more difficult. Trimming/filing of the shell is required for the PCB to fit, due to the audio/antenna jack. A 3d printed cutting guide is available as an optional purchase, or you can print your own.

Please do not purchase the DIY version unless you are confident in your ability to solder these parts and complete the project! Again, please view the DIY assembly guide before purchase to ensure you understand what is required.
