Geehy low-power Bluetooth chip GW8811

The GW8811 series of ultra-low-power Bluetooth 4.2 chips is based on the 32-bit Arm® Cortex®-M0 core. Integrates a high-performance 2.4GHz RF transceiver and rich digital interfaces; integrates Balun, eliminating the need for off-chip impedance matching networks and external crystal oscillator load capacitors, which can save BOM costs and PCB area to the greatest extent; integrates high-efficiency DC-DC reduction voltage converter to achieve ultra-low power consumption.
