Wireless UART RF Module -RF3100

RF3100 Wireless UART Transceiver converts traditional UART to wireless communication. There are three selections of frequencies: 433~435 MHz, 868~870 MHz, or 902~928 MHz. It is a transparent transceiver module that integrates low transmission power and high receiving sensitivity designs. Compared to previous models, RF3100 provides higher communication speeds up to 76.8 Kbps and longer distances up to 600 meters. The modules get approvals from Europe ESTI(EN300-200-1 and EN301-439-3) and FCC 15.247. It meets the wireless regulation and saves the application for approval of frequencies.
