Variants

Most ShieldBuddies are fitted with the TC275 CA-step processor. The later DC-step processor is fitted to some and this will become the norm in 2018. If you are using the Arduino IDE add-in and basically using the ShieldBuddy as a super-fast, triple core Arduino then there is no difference. Advanced users who program it via Eclipse will be able to use CAN-FD as this is available only on DC step onwards. There are some minor bug fixes in the silicon but these are in obscure functions that only people like Bosch might use. The current ShieldBuddy production has the USB connector moved so that it is now in the same place as on an Arduino Mega so that it can be used in things like the MDUINO21 Arduino-based PLC from Industrial Shields in Spain. However these exist as both CA and DC-steps!
