Using the Adafruit si5351 Board

Many constructors are using the Adafruit si5351a i2c board with their µBITx as part of a Raduino replacement (often in conjunction with a processor upgrade and feeding the display with an i2c daughter board).

Note that the Adafruit board does not have 0.1uF capacitors on the outputs of the three clocks.   You will need to find a way to incorporate these capacitors in your circuit.
