CAN Bus Shield for Arduino, Mbed Platform With Fault-Tolerant MAX33040E CAN Transceiver
Posted by on
The MAX33040Eshld shield evaluation kit by maxim integrated represents a demonstration and development platform for the MAX33040E CAN Bus transceiver. It serves as a standalone evaluation board and the Mbed or Arduino platform to communicate with a CAN Bus network. The board features test points to access critical signal pins of the transceiver. The MAX14931 digital isolator is used as a level translator with a 1.71 VDC to 5.5 VDC supply range which also feeds the micro-controller. The onboard microSD card socket supports OBD-II (vehicle diagnostics) applications.
The MAX33040E/MAX33041E are +3.3 VDC Controller Area Network (CAN) transceivers with integrated protection for industrial applications. These devices possess extended ±40V fault protection on CAN_H and CAN_L for equipment where overvoltage protection is required. They also incorporate high ±40 kV ESD HBM and an input common-mode range (CMR) of ±25V on CAN_H and CAN_L, exceeding the ISO 11898-2 CAN Standard of -2V to +7V. This makes these parts well suited for applications enduring moderate electrical noise, influencing the ground levels between two nodes or systems. The transceiver features a shutdown pin and a multifunction standby pin.

Teensy 4.0 Triple CAN Bus Board With Two CAN 2.0B And One CAN FD Port
The Teensy 4.0 Triple CAN Bus Board is a Teensy 4.0 board with triple CAN Bus connections, two Classical CAN 2.0B, and one CAN FD. It can be powered by an external +12 VDC power supply with reverse voltage protection.
The Teensy 4.0 is an Arduino-compatible board with an Arm Cortex-M7 microcontroller running at 600 MHz. The board is compatible with the Arduino IDE and the Arduino library. In most cases, code written for another Arduino board works with a minimum of changes on a Teensy.
