The WattUp Hearables Developer Kit

Enabling Faster Integration of Energous’ WattUp Wireless Charging Technology Into Customer Product Designs

The WattUp developer kit for hearables supports higher power delivery and fast-charging for a wide variety of hearables, such as Bluetooth earbuds, smart headphones and more.

The hearables reference design transmitter incorporates the DA14680, DA4100, EN3921 ICs and EN3913M module. The DA4100 is a highly integrated system-on-chip RF transmitter IC, the EN3913M is a highly-efficient, 2-stage GaN power amplifier (PA) controlled by the EN3921 IC, while the DA14680 supports full Bluetooth low energy 4.2 features.

On the receiver side, the DA2223 RF-to-DC receiver can be connected to up to four antennas and the DA14585 is a size-optimized, ultra-low power Bluetooth low energy system-on-chip ideal for small form factor product designs.
