    item came within reasonably good time for the free postage, on initial testing although still some tinkering to do for it intended purposes it worked straight off a 12v supply as input but its out of the factory setting reading 16,4v no load and the adjustment pot worked when trying to raise voltage or lower it as expected? so far i have allowed it to run for 2 hours after setting to 13v and its kept within 0.1v good enough regulation. appears to use a Texas instruments TL-494 driver chip

    Item was as advertised and the delivery fast, BUT the item was insufficiently packed. It is a relatively fragile electronic module and posting it in just a paper envelope is not sensible or sufficient packing. By luck the module was not damaged. Seems this seller is scrimping on packing. Not a good move.
