Tehnilised andmed

This module is a module that converts a TTL signal into a CAN signal. The serial port is used as the interface of the embedded system, the data transmission is simple, there is no need to learn the CAN protocol, the development cycle is shortened, and the development cost is reduced. The module is compatible with 3.3V, 5V power supply, and the small area is semi-hole technology, which is easier to embed in the system.

The module is equipped with a 32-bit ARM processor and a CAN level shifting chip. 14 sets of masking filters, each with five frame filtering methods. The parameter is set to the AT command setting mode, the command is simple and concise, and there are only 6 instructions. A wider baud rate range is more adaptable to the network.

The serial port of this module is TTL 3.3V signal, which cannot be connected with 232 signal! If you want to interface with a 5V system, it is best to have a 5V to 3.3V circuit.
The module has a status indicator that is 1 Hz when in communication mode and 5 Hz when in configuration mode.

The ARM processor with Cortex M3 core has stronger data processing capability and lower power consumption. The processor integrates the CAN controller to make the transmission more time-saving.
