Restaurant Order Dishes System rf Module High Transparent Wall 433M
Description
The VT-DTMSD3
433 module is designed as a wireless sub module for wireless communication between devices like controls, POS systems, data collectors etc which based on TI’s high performance CC112x chip, integrated 32 bit ARM Energy Micro Cortex-M3. Industrial grade chip and high performance transceiver were integrated on small size RF module.
VT-DTMSD3-433 is transparent transmit, means received same as transmitted. Outstanding advantage are long transmit distance, low power, multi port etc. User do not need to programming and control it, short R&D time. VT-DTMSD3-433 take use of MCU package and processing, then user use UART port to realize wireless transmit. This module is easy to use for users, that no need to programmed software for wireless communication.
