Ant2 LiPo Charger: The smallest USB Type-C LiPo charger

The Ant2 is a tiny USB-C lithium polymer charger that measures just 16 x 9mm, just larger than the USB Type-C connector itself. It is the smallest charger in its class. Ant2 can be used to add USB-C power and battery charging support to space-constrained prototypes and projects. The small size also makes it easier to retrofit USB-C power into your old projects.

Data Fitness Connector (DFC): Allows Peloton bikes to communicate with fitness watches and other connectors (schematic, source code, PCB, etc.)

Data Fitness Connector (DFC) A data broadcaster is a device that allows Peloton bikes to communicate with fitness watches, head units, and apps, a feature not available on stock Peloton bikes. It reads power and cadence data in real time via a cable connected to the bike and broadcasts them wirelessly to nearby devices, including those built around non-Peloton platforms like Zwift and Garmin (see which products are supported). This allows you to enjoy the built-in features of your bike while taking advantage of features and services that rely on third-party platforms.

Air mouse (remote control)

Most smart controls combine RF functionality with smartphone control capabilities in affordable packages. These smart controls are unique universal remote systems capable of controlling multiple devices. The ISD9160 remote reference design is extremely thin and light, and operates via RF rather than infrared, so you don't need to point a straight line at your component. The ISD9160 smart control reference design combines RF functionality and smartphone control in an affordable, universal remote kit. The reference design also supports Skype/Voice calling, with the remote becoming a headset with volume control and microphone support. The remote control can also be used as an air mouse that supports ITG-3050 Gyro (3-axis) and MMA-8451 (3-axis) G sensor modules.
