Key Features
- Bluetooth 5.0 Core Technology: Powered by a high-performance Jieli (JL) system-on-chip paired with a dedicated 24.000 MHz crystal oscillator (Y1) to ensure lightning-fast pairing, extended wireless range, and ultra-stable connection tracking.
- Ultra-Compact Footprint: Miniature circuit architecture allows it to fit seamlessly inside small enclosures, handheld audio gadgets, and tight internal housing layouts.
- Integrated PCB Trace Antenna: Features a multi-segmented copper trace antenna etched directly onto the left side of the board, eliminating the need for complex, bulky external antenna structures.
- Low-Noise Audio Decoding: Built with a precise network of micro surface-mount smoothing capacitors (C1, C4, C9, C10) and resistors (R1, R2, R3) that filter power ripple noise to deliver clean, crisp audio outputs.
- Clear Solder Pad Layout: Outfitted with pre-milled, heavy-duty through-hole solder pads on the right edge, clearly segmented into a 3-pin audio array and a 2-pin power terminal for easy installation.
