I do not recommend this seller. Wasted time for 10 weeks. Very long time did not send out the items, then added non existent tracking number. Then lied that it is just delay in info update. Nothing changed and not came even after month. Then he cancelled the shipment. He ignored dispute until the last day, willingly not going to return the money. Before dispute, he answered once/twice a week with random, inappropriate reply. Nothing official in this store.
I bought two modules but all modules don’t work. it looks be maxim line driver broken. and jumpers area wrong direction.
