Connecting the Board
The form factor of the ATECC608A Trust Development Board was chosen because Microchip has heavily adopted
the use of the mikroBUS connector on host boards. Many of Microchip’s development platforms will support one or
more mikroBus interfaces. These include:
• Microchip Explorer 16/32 Development Board
• MPLAB
®
Xpress Evaluation Board
• Automotive Networking Development Board
• PIC
®
Curiosity Boards
• PIC Curiosity Nano Boards
• AVR
