No. The FPP developers are strong proponents of Open Source, Open Hardware, and the DIY community. As a way of showing this support for our DIY cape users, we are providing free vouchers which can be used to “purchase” a License Key from Shop.FalconPlayer.com for free. If you have a cape which you built for your own personal use, all you need to do is send a picture of the cape to diy@falconplayer.com and we will send you the free voucher. The cape must be setup to use either a programmed physical EEPROM or a Virtual EEPROM provided with FPP. After securing a License Key, the EEPROM will be signed and allow full functionality on your DIY cape.
