ANT

RF signal output.
If you need to use an external antenna, you can shield the onboard antena by modifying the module on the 0R resistor. Or contact Feasycom to modify.

Hardware Design Note

  • In simple test environment, the module can be used for basic testing and operation by simply connecting VDD, GND, UART_RXD, and UART_TXD.

  • If the MCU needs to obtain the connection status of the Bluetooth module, it needs to be connected to the STATUS pin.

  • After drawing the schematic diagram, please send it to Feasycom for review to avoid Bluetooth distance not achieving the best effect.
