As it happens once in a while, I acquired a lot of 5 nice dc/dc new converters from ebay for 9 bucks, but now I got them I lack basic information about the product.
"Specifications" I have for them are limited to following: DC/DC Converter 5V Input, 3.3V @ 5A Output SMT
The boards look like following on the pics:
I see 4 "tunnel shaped" connectors on the back side. Could anybody tell me which connectors are for the input VCC in 5v / GND and which for output VCC out 3.3v / GND?Or could anybody tell me how I could test the connectors to determine that without destroying anything?
Any help on this would be greatly appreciated since I intend to use the board to power my LS20032 GPS chip which just arrived from SparkFun! Thanks all for your attention.
