CH9143 Mini Module BLE/UART/USB Module BLE/USB to Serial/TTL UART Module

The CH9143 is a BLE/UART/USB three-way chip that enables data transfer between Bluetooth, USB, and serial ports. Bluetooth supports host mode, slave mode and master-slave integrated mode, and Bluetooth communication and parameters can be configured under slave mode and master-slave integrated mode, supporting BLE4.2. The serial port supports AT configuration, supports MODEM contact signal, and has a maximum baud rate of 1Mbps. At the same time, it can realize online debugging or data monitoring between computer USB interface, serial port and Bluetooth. USB and BLE virtual serial port technology, the computer side provides a virtual serial port driver, shielding Bluetooth and USB underlying technical details, no secondary development, that is, compatible with conventional serial port applications and serial debugging tools, quickly achieve three "serial port" transmission to each other. Data transfer between BLE, USB, and UART. BLE supports slave mode, master mode and master-slave mode. PC-side USB and BLE virtual serial port driver provided. Compatible with existing serial port software and tools, with no secondary development required. Supports Bluetooth host connection in Windows/Linux/Android/iOS and other systems. 2 serial port driver modes: driver mode and installation-free USB-CDC driver mode. 100m BLE transfer distance. Adjustable 8 positions of BLE TX power. Supports BLE transfer configuration and serial AT configuration. Maximum baud rate of serial port is 1Mbps. Serial port supports MODEM signals: , DTR, DCD, RI, and . Serial port supports 5/6/7/8 data bits and 1/2 stop bits. Serial port supports odd, even, no parity, space 0 and . Full-speed USB device interface, USB V2.0 compliant. Colour:Black Material:PCB+electronic nents Different batches may have different appearance, which does not affect use.
