How to substitute TJA1050 with SN65HVD230 in shareproject

How to order a shareproject except with a different chip?

Want to substitute the TJA1050 CAN transceiver (5V) with SN65HVD230 (3v3).

Or is there an easy way to clone the project and change the part list?


Here is the CAN board project

https://www.pcbway.com/project/shareproject/CAN_Bus_Communication_Module_MCP2515_82bfe215.html


Would it be possible to create a similar project replacing the 5V TJA1050 with 3v3 SN65HVD230 and run board at Vcc 3v3 instead of 5v?

This would solve problem of having to level shift the SPI signals for use with ESP32 that has 3v3 GPIO that are not 5V tolerant.

Note the MCP2515 works at both 3v3 and 5V, and the SN65HVD230 is pin compatible with TJA1050.
