2020 iot new 868MHz CC1310 433MHz UART Wireless 1KM RF Transceiver Module
Low Cost Long Range 868MHz CC1310 433MHz UART Wireless 1KM RF Transceiver Module
VT-DT2-S02C-433/868/915M serials RF transceiver modules are designed based on TI high performance SoC IC CC1310, which combines Sub-1G wireless transceiver and an ARM® Cortex®-M3 processing core, and can cover ultra long range and be ultra low power.
The serials modules transparently transmit data, i.e. what you receive is what you transmit. There is no requirement for users to put effort on programming to control the RF part, but only treat the module as a UART terminal, connect the UART interface and then let data be transmitted and received. It helps users saving much more time for product development.
CC1310 has Long-range Mode (LRM) which is similar to LoRa. When TX power 15dBm and data rate 625bps, it can cover 3km range communication. The module’s RX current is 6.2mA, and the current under shutdown mode is only 185nA. They are especially suitable for the applications under low battery field such as fault indicator, SmartGrid and Automatic Meter Reading, environment monitor, etc.
VT-DT2-S02C-868M serials RF transceiver modules include 433MHz, 470MHz, 510MHz, 868MHz, 915MHz, also include modules with RF PA. The corresponding pure hardware modules are named “VT-S02C/VT-SA02X”, and user can easily choose what you want.

Description | Reason and Solution |
Can’t communication | 1.The power supply connect not well, check the module VCC whether it is out of maximum rating. 2.The signal line connect not well, check the module SPI interface. 3.The settings of the transmitter module and receiver module are not the same. Check these modules’ register configuration. 4.Signal block. If the transmitter work with a high TX power, and the receiver was put at a short distance(<0.5m), maybe there is a signal block to make no communication. |
Communication distance is too short | 1.The application environment is too bad or the antenna is shield. Put the antenna to a better place outside or higher throw a coaxial line , replace it with a higher gain antenna. 2.The work space contains a same frequency interference source, or a strong magnetic field interference, power source disturbance. Try to change the carrier frequency or get far away from the source of the disturbance. 3.The power supply is not strong. Check the voltage and the current whether it is enough. |
High data error | 1.The power supply ripple is too big, Change the power supply. 2.Check the module register configuration, it is recommended to set as the CC1120-datasheet. 3.There is a carrier frequency interference, change the channel. 4.The antenna unmatched to the module RF interface, change another matched antenna. |
