What is the part number for the CAN transceivers used in the Cube Black and Cube Orange?
These are parts U3003 and U3004 found on sheet 3 of the Cube Black PDF schematic, and parts U16 and U18 found on page 9 of the Cube Orange PDF schematic.
p/n: TJA1051TK/3,118
After some digging around I noticed that the FMUv3 Pixhawk Open Hardware Design bill of materials lists the CAN transceiver as MAX3051EKA+T which fits the pin names in the Cube Black/Orange schematics perfectly and a PCB photo shows it has the expected top marking (“AEKF”).
I think that the TJA1051TK/3,118 mentioned above can’t be right, since it is intended for 5 V operation while the Cube feeds 3.3 V to the transceivers. Additionally, pin 5 of the transceiver is grounded in the Cube schematic which doesn’t make sense for the TJA1051TK/3.
