Bluetooth 5.0 BLE serial port module provides faster communication rate than Bluetooth 2.0, with up to 230,400 baud rate for smoother data transmission.

When the broadcast interval is set to a maximum of 10 seconds, the s l e e p current is 4.5uA (discoverable and connectable), and a CR2032 battery can last for 1400 days, the HC-42 B luetooth 5.0BLE serial port module is a natural choice for applications that require a high power consumption.

Antenna is led out by a we Idable wire at the end. High precision crystal vibration 32.000HMZ. State of the LED Blue indicator blinks. The module is not connected and enters the AT command state Blue indicator is steady on. The module is connected and the transparent transmission mode is enabled. NRF52832 chip scheme Bluetooth 5.0BLE protocol. Stamp hole package Easy to embed in appli cation system.
