The GW3323 Bluetooth smart wristband solution enables one chip to meet the dual requirements of "wireless connectivity" and "algorithm processing", helping to innovate product applications and enhance market competitiveness.

GW3323 Bluetooth Smart Wristband Solution

The solution supports low-power Bluetooth 5.2 and classic Bluetooth SPP communication protocols, which can achieve greater compatibility and interconnection with more Bluetooth devices. With a built-in high-performance 2.4GHz RF transceiver and 0.2A charging current, it has higher integration, stronger connectivity, and lower power consumption, which helps to reduce production costs, improve transmission performance, and expand application functions.
