DL-RTM300-B RF Module is an UART wireless serial port module with AT commands. It combines an integrated RF Controller with ARM Cortex-M0 32-bit core, 64kB on-chip Flash, 8kB on-chip SRAM, and supports hardware parity check. The Clock Speed of the main frequency can reach up to 48MHz. The high efficiency of receiving sensitivity enables this RF module to have excellent RF performance and strong anti-interference ability in the 420-510MHz/860-950MHz frequency bands.

The 868/915Mhz RFM95 Wireless Transceiver Moduless feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

1.8KM Range 915Mhz RF Transceiver Module, -120dBm Receiving Sensitivity, Pin to Pin with HopeRF's RFM300-915S2 RF Transceiver Module

DL-RFM96 is a SX1276 chip based Wireless Transceiver Module, which adopt LoRa modulation technique, can achieve a sensitivity of over -140dBm. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness.

DL-RFM69HC is a wide-band transceiver module designed with Semtech's SX1231 chip, which can work in the 315/433/868/915MHz ISM open frequency band.
