Product Information
BT20/-A Bluetooth module support ODA aerial upgrade BLE5.0
Model Number：M2021025:BT20/-A
BT20 Bluetooth module, support ODA in-flight upgrade, ultra-low power consumption, BLE5.0 high-speed transmission, Android and Apple dual system support, pin, patch two specifications to choose from.
The performance of the baseplate module is the same as that of the patch module. The baseplate module supports the TTL voltage of 3, -6V, and can be directly connected to most of the 5V microcontrollers

Pin Definition
Pin 1-UART_TX: serial port data output, pin 2-UARt_TX: serial port data input, Pin 11-resetb: low reset (at least 5ms), pin 12-VDD: Power 3.3, pin 13-GND: ground, pin 14-GND: ground, pin 15-DIO_4: disconnect pin (200ms low electric pulse disconnect), pin 16-DIO_5:LED lamp pin (not connected blinking, connected on), pin 17-DIO_0: Bluetooth connection indicator (not connected low, connected high)
Instruction Set Specification
Dx-bt20 5.0 Bluetooth serial port module commands for the Command set (AT Command is case-insensitive)
The AT command must end with carriage return or \r\n or hexadecimal 0D0A. The AT command can only take effect when the module is not connected. Once the Bluetooth module is connected to the device, the Bluetooth module will enter the mode of transparent data transmission
Application
Intelligent toys, instruments and meters, printers, medical equipment, massage chairs, intelligent door locks and so on
