The antenna is an important part of the communication system. Its feature directly affects the performance of the communication system. The match impedance of module is 50 ohms, we recommend that users adopt standard spring antenna.
USB converter board:
Modules needed by configuration tool to configure the relative parameters. The Company supplies a USB interface matching plate adapter with TTL/RS232/RS485 level, so that users can quickly and easily with the PC side communication.
If you need another frequency band 433MHz, or TTL/RS485 port, just leave message please!
