 Make sure your Arduino board can work with [STLink](http://www.st.com/en/development-tools/st-link-v2.html), [Jlink](https://www.segger.com/jlink-debug-probes.html) or [EDBG](http://www.atmel.com/webdoc/protocoldocs/ch01s01.html). The debugging support currently is fully tested with the following boards.
 - [MXChip IoT Developer Kit - AZ3166](https://microsoft.github.io/azure-iot-developer-kit/)
-- [Arduino Zero Pro](http://www.arduino.org/products/boards/arduino-zero-pro)
-- [Arduino M0 PRO](http://www.arduino.org/products/boards/arduino-m0-pro)
