The DAPter v1.1 is a DAPlink interface for Master modules. Arm® Mbed™ DAPlink is an open-source software project that enables programming and debugging application software on running on Arm Cortex CPUs. Commonly referred to as interface firmware, DAPLink runs on a secondary MCU that is attached to the SWD or JTAG port of the application MCU. This configuration is found on nearly all development boards. It creates a bridge between your development computer and the CPU debug access port. Furthermore, thanks to the DAPter, a device can very easily become Arm® Pelion™ Device Ready. Find out more about Arm® Mbed™ DAPlink. What makes the DAPter module stand out against other DAPlink applications, is that it can be used on any device, it doesn't matter if it is an early prototype or a product in mass production. Just click the Adapter module between the compatible Master module and the motherboard and as soon as it its turned on, it has all DAPlink capabilities.
