Spektrum BT2000 DX3 Smart Bluetooth Module, SPMBT2000 4.6 x 4 x 0.47 inches

What information are you looking for to get the Bluetooth module? This is the module that plugs into the DX3 transmitters. https://a.co/d/0iQjfcM5 I'm asking as if you have multiple arrma cars (or even put a spektrum receiver in a traxxas) and upgrade your transmitter to something like a DX5, the transmitter will show the same telemetry data and more. Granted purchasing the Bluetooth module is cheaper than getting a better transmitter. For instance here's a screenshot from in the app. All this plus more I can see on my DX6R screen.
