The DL-RTS1278M Communication Module is a low cost, low power embedded mini controller solution from DreamLNK. This RoHS compliant device is designed to be used for remote control applications, such as remote surveillance, remote switch control, automation equipment, and energy management systems. It features integrated 4-ports for serial communications, providing interfaces for RS232, RS485, Ethernet, and CAN-Bus. It also supports various communication protocols, allowing it to directly control devices such as IP cameras, serial switches, digital valves, and digital sensors. With on-board expansion, it can be extended to meet more complex multi-device communication needs. The module is powered by a 32-bit ARM Cortex M4 microcontroller and a rich set of integrated peripherals, including a 10-bit A/D converter, SPI, I2C, timer/counter, and watchdogs.
