Wearable device power supply reference design for wireless charging using bq51003 and bq25120

Wearable devices require advanced power management to keep batteries running for extended periods of time while enabling always-on functionality. In addition, the device needs to use small rechargeable batteries and support a small form factor design. This application note shows how to implement a scalable power management solution for wearable devices that can be customized for activity monitors or smart watches. This design features a Li-ion battery charger and low quiescent current (Iq) DC/DC buck and boost converters for PMOLED displays, a boost converter for heart rate monitors (HRM) and a second Configured with low Iq DC/DC buck, it provides wireless charging input and highly configurable battery management solution.

MAXREFDESGPS_B: How to add GPS to your product without draining your battery

The GPS reference design is an evaluation kit designed to demonstrate the essential features of an ultra-low power GPS (global positioning system) receiver, as well as serving as a reference design to illustrate how to implement such a receiver rapidly. The reference design uses the MAX2769C L1-band GNSS RF front end IC (RFIC) from Maxim Integrated, and the ultra-low power GPS baseband processing firmware provided by Baseband Technologies Inc. (BTI) that runs on a MAX32632 microcontroller unit (MCU).

ecpbreaker: Based on icebreaker FPGA board, upgraded ECP5

The icebreaker project is a very nice and handy little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.

Teacher ChaN’s latest power strip

The style of enameled wire is as usual, and the craftsmanship is still excellent. The power board designed this time is made of double panels, and a copper-laying design is applied. The insulation layer is laid first and then the copper. If the device on the front needs to be grounded, break the insulation layer and solder it to the copper.
