The hardware of the two modules is identical, with the only difference being at the software level. Both modules are equipped with transmitting and receiving capabilities, and their RF specifications—including transmit power and spectral bandwidth—are consistent. The distinction between the two modules lies in their data throughput: the transmitter module supports a throughput of only 600 kbps, whereas the receiver module achieves a throughput ranging from 2 Mbps to 7 Mbps.
