We even have nice hardware flow control so you won&#39;t have to think about losing data. Connect to your Arduino or other microcontroller or even just a standard FTDI cable for debugging and testing.<br /><br />This multi-function module can do quite a lot! For most people, they&#39;ll be very happy to use the standard Nordic UART RX/TX connection profile.
