6. SMD Jumpers
The Accel Click™ board communicates
with the main board via I
2
C or SPI interface
depending on the position of the J1, J2 and J3
SMD jumpers. These jumpers are soldered in
I
2
C interface position by default. There is an
option to select the alternate address with
jumper J4 in the case of I
2
C interface (default
position is logic 1).
