Jumper settings:
1. J7 and J10 are used to isolate the UART port for the ATSAMD21 microcontroller
when programming the Bluetooth module PAN1740, or engage the board into
Arduino mode.
2. J9 and J12 are used to set up the evaluation kit into either independent mode or
Arduino mode. When J9 and J12 are in-situ, the sensor and ATSAMD21 are
connected via I
jumpers will enable the Arduino mode when the Grid-EYE board is hosted onto the
Arduino board. If not hosted onto the Arduino board and jumpers are removed
unexpected and undefined data will be received and/or transmitted.
3. When programming ATSAMD21 with SAM-BA, J18 is placed in-situ to update the
bootloader or start the application. By having the jumper J18 connected and the
reset button SW1 pressed, ATSAMD21 will be ready for updating the bootloader.
