Just remember that to route the clock signal to the external clock connector on the Lime mini you need to rotate a SMD resistor. Also it will then fail the LimeTest routine if you run it because during the test of the clock circuitry the DAC driving the onboard VCTCXO is exercised. It makes no difference to the operation it just shocks you a bit if you run Lime test after doing the resistor mod.
