Neptune is a cost and performance optimised reference design for portable Bluetooth audio streaming devices, including simple Bluetooth pairing using low cost NFC tag and DAB/FM radio capability. The platform also demonstrates iOS device docking via an Apple Lightning dock using iAP2 and is compliant to MFi (Made For iPhone/iPad) standards. Two variant of Neptune are available, with and without physical iOS docking capability. Neptune can be used to evaluate a number of device applications including full Master mode with graphic display, rotary controls and keypad, Headless device (using LEDs to indicate operation) and Slave mode.
Based on Frontier Silicon’s Tuscany module, the Neptune reference platform supports Bluetooth streaming audio, enabling a new generation of battery and/or mains powered Bluetooth wireless audio products. Neptune operates as a DAB/FM radio, wireless speaker and docking platform with full graphic display and can also be used as a headless Bluetooth docking speaker.
The Neptune platform incorporates high quality acoustic design, powered by Tymphany Peerless drives, to demonstrate the excellent audio capabilities of the Frontier Silicon architecture.
Neptune is provided with a full engineering design pack including detailed specification, schematics, gerbers, bill-of-materials, software, EMC and ESD compliance reports. Support is available to customise the platform for individual requirements. The platform is production-ready and needs only industrial design tooling to finish off a complete high-quality audio system.
The fully-flexible reference design comprises three main PCBs, an iDevice daughter board and the Tuscany module.
