Description

Breakout board for ADAFRUIT Feather based on MCP2515 CAN controller with an 3.3V CAN transceiver. This board also connects the various interrupt lines to the Feather to allow for better communication performance especially at higher CAN bus bitrates at the tradeoff that a couple of IO pins are occupied by the CAN FeatherWing. I added 0R resistor bridges into each interrupt line. So if interrupt controlled access is not wanted remove the 0R resistors. Feedback welcome! ![Final Prototype][1] [1]: /editor/20160811/57ac53b30409b.jpg
