: Often sold in 2-piece packs for approximately ₹1112 ₹887.
) Errors: The roughly 80-Ohm internal resistance of the 74HC4051D chip forms a voltage divider with the source impedance of your sensors. When building high-precision instrumentation circuits, use operational amplifiers configured as voltage followers to buffer high-impedance sensor signals before feeding them into the multiplexer matrix.
Note: The CAN bus must have a 120Ω termination resistor at each end. 6. Common Applications
The module is based on the NXP TJA1051 chip , which is an advanced successor to the popular TJA1050. It provides differential transmit and receive capabilities, allowing microcontrollers to communicate over long distances in electrically noisy environments. Transceiver Chip : TJA1051. Data Rate : Supports high-speed CAN up to 1 Mbps .
The WCMCU1051 replaces older-generation transceivers like the TJA1050. Upgrading to this hardware introduces several core structural fixes:
Due to its reliability and high speed, the WCMCU1051 is frequently found in:
termination resistor must be placed across the CANH and CANL lines at both terminal ends of the physical network. Diagnostic Troubleshooting Flowchart
. It is designed to interface directly with 3.3V or 5V microcontrollers like Arduino, STM32, and ESP32. Protection Mechanisms Short-circuit protection for bus lines. Thermal shutdown and current limiting. TXD dominant timeout
: Ensure your microcontroller's firmware is initialized with identical baud rates (e.g., 250 kbps or 500 kbps) across all active nodes on the network.
