How do I remove the RK3188-SOM main board from the RK3188-SOM-EVB peripheral board? It looks like a very tight fit.
Try to use a thin and long object as a lever. Carefully place it on a spot that won't damage other components. Push each side slowly up before attempting to pull out the RK3188-SOM-4GB from the RK3188-SOM-EVB's connectors.Never try to remove the whole side in one go! Doing so would most likely damage the connectors and the male pins! Always try to symetrically push up the RK3188-SOM frm the EVB.
