Description
Product Overview
Ling-TRL is two-way serial port transparent transmission module which applies GFSK frequency modulation technology and work on 2.4G free frequency.It features free-development, low-power, automatic switching between transmitting and receiving. It can be quickly debugged successfully if communication protocol is provided and upper computer set the software, it’s also flexible to set the power, channel, network ID and other parameter. Users who know about interface communication can develpe the wireless remote control product and data collection product , rich knowledge about wireless communication is not necessary. Low power performance is also more suitable for battery application.
