M139 PwrCAN Module 13.2

M5Stack M139 PwrCAN Module 13.2 is a versatile module for the PwrCAN bus, featuring isolated CAN communication and a 9V_DC to 24V_DC power bus. The M5Stack M139 also supports Pwr485 (with isolation) and provides an isolated 5V power supply to the M5 host. The module uses the CA-IS3050G isolated transceiver for CAN communication and the CA-IS3082W isolated transceiver for RS485 communication. The GPIOs for CAN and RS485 communication, and the 120Ω terminal resistance at the CAN and RS485 outputs, can be selected via dip switches. The module's power bus accommodates a 9V_DC to 24V_DC input, with connections available through HT3.96 and XT30 connectors. The built-in isolated power module F0505S-2WR3 supplies power to the M5 host. This module is ideal for applications in robot control, protocol conversion, industrial automation, automotive communication systems, intelligent transportation, and building automation.
