Three sizes are prescribed for mikroBUS
™
add-on boards: S, M and L. When designing yours, use the smallest size sucient to hold a
given module. Sensors and transceiver chips will t on S or M in most cases. Odd-shaped encoders or larger connectors will require an
L. Whichever size you use, make sure to retain the notch on the bottom right corner of the board (serves as a guide for proper insertion
into the socket). Otherwise, you are free to experiment with the shape of the board as long as its conned into these dimensions.
