HY0021 Bluetooth® LE v5.4 Module

The HY0021 from FDK is an ultra-compact Bluetooth low-energy module. The slot antenna on shielded package technology has a small module with a built-in 32 kHz crystal and DC/DC circuit components, a small occupied area for printed circuit boards, and a high wiring design flexibility. It can be used for small and highly creative or unique products. Despite its small size, the module integrates a high-speed quartz crystal unit, a low-speed quartz crystal unit, and passive components around the power supply. Connecting sensors and batteries to the module quickly and easily configures a low-power consumption IoT component that can connect people and things.
