I have a small CAN transceiver board. It will take an ISO1050, or a number of other transceivers. It has on-board power regulator, and RJ45x2 connectors. Interface is CAN-RX and TX, GND, and two power in/out, so its very flexible. I could convert to a shield/booster-pack, but this is more useful since it can connect to any of my dev boards: Tiva, Arduino, NXP, Nucleo, etc.
