OMx02 DataSheet 1.1 www.manthink.cn 1 / 10 T EL：+86-010-56229170 OM802S LoRa Module with Open Source OM802S is a highly integrated low-power half-duplex RF transceiver module embedding high-speed low-power MCU and high-performance RF chip with LORA modem which is capable of achieving significant longer range than existing RF transceiver based on FSK or OOK modulation. OM802S can support secondary development to realize an application of LoRaWAN with the SDK supplied by ManThink, OM802S have abundant hardware resource to realize different function which include SPI, IIC, AD and DIO. This module uses LoRa modem to improve the sensitivity up to -137dBm, significantly extending the transmission distance under a low power. Under LoRaWAN protocol, the start network can solve the problem of collision and low power consumption through gateway solution. OM802S module’s interface voltage 2.6- 3.6 V with consuming only 13 mA at the receiving mode. If there is no packet to transmit, the module consumption is only 3uA which is very suitable for a battery- powered system. Using the OM802S module in an application minimize the need or an expensive and time- consuming RF development. Fast time to market is possible with this pre-qualified module.

It operates in the license free frequency band . The OM802S uses Semtech’s patented LoRa modulation technique which combines Spread spectrum modulation and forward error correction techniques to increase the range and spectrum modulation and forward error correction techniques to increase the range and robustness of radio communication links compared with traditional FSK or OOK based modulation. Typically examples of OM802S receive performances are given in the following table. Table 1 : performance of LoRa with different parameters The module is solderable like a SMD component and can easily be mounted on a simple carrier board with a minimum of required external connections.
