Embedded SPI or UART to CAN module

CSM series embedded SPI/UART to CAN module can help you quickly conduct the project design of apparatuses and instruments with CAN-bus communication interfaces.

CSM series integrates 32-bit microprocessor, CAN controller, CAN transceiver, power circuit, isolation circuit and bus protection. All components are arranged in a miniature package module. The module dimension is only 31.80x20.30x6.50mm, which is equivalent to a DIP-24 integrated circuit. Although the module is small, it has complete functions. Without connecting with any peripheral components, CSM series can connect the device to the CAN-bus network via SPI or UART port.

CSM series protocol conversion module makes interface expansion simpler

CSM series products support SPI or UART to extend the CAN interface. You can choose any of SPI and UART interfaces, which is more flexible. They support multiple conversion protocols, which is more convenient. The signal power supply is fully isolated, which is more reliable.
