Which pins do I need to wire to use this like an HC-06?
According to Seeed Studio, this module uses UART pins, but as far as I know, Arduino Pro Mini doesn't have UART pins. So how should I wire these two?
Of course it does. RX and TX (pins 0 and 1) are UART pins, intended for program download and serial monitor communications. It is possible to use them with a radio, but not while downloading code or using the serial monitor.
You can have a separate serial connection on other digital pins, using the SoftwareSerial, NeoSoftwareSerial, or AltSoftSerial libraries, and that is what most people use with radios.
