Teltonika FMB140 - CAN Bus Tracker
GNSS/GSM/Bluetooth® tracker with integrated CAN chip, internal GNSS/GSM antennas and internal battery.
Product Details
The FMB140 is the CAN model: an integrated CAN chip with two CAN channels reads the vehicle bus directly, with no OBD dongle in between. Where the FMB920 needs a Bluetooth OBDII dongle for engine data, the FMB140 takes it straight off the wire — the right choice for trucks, buses and machinery.
