[FAQ]bill.huey asked about Serial CAN-BUS Module based on MCP2551 and MCP2515

Hi, I just bought one of these boards and I have to adapt it for use in a system that's 3.3v. Typically the MCP2515 are 5v systems petit specifies that works with 3.3v. What's the actual story here with the working voltage ? I'm ultimately going to try to put in on a SPI bus with logic levels of 3.3/5v (level shifted from a 1.8v 96boards system) and I was wondering if I can power the board from a 5v source and the specification above are a mistake ? If not, then what's needed to drive it ?
