Hi Friends,
I bought 5 MSP430-CCRF for making some prototypes about a network sensors.
The sensor need to work only with battery so, current consumption is really important.

So I do some tests and I got in LPM4 a current consumption about 9uA.
But unfortunately I got this result only on 3 of my 5 boards. In the other 2 boards I got 90uA in LPM4.
This mean that this two boards has a hardware problem.

So I need to be sure than, the next order I will do I GOT ONLY GOOD BOARDS!!
Can someone of Olimex give me information about this problem?
Does the Olimex ATE do a LowPower Test in order to ensure the customer about the quality of the boards??

Up!

Please someone of Olimex can answer me?? I wrote to Support Email too but without success. I need to do this order and I NEED TO BE SURE TO GET GOOD BOARDS!!

Yesterday, supported from a colleague of mine (hardware engineer) we found a problem of my two boards:
the problem was in the MCP1702 and capacitor C2 and C3.

So, being sure that the boards where just unboxed from Olimex shipping box, I ask you again:
DOES YOUR BOARDS EXECUTE AN ELECTRICAL TEST, with a classical ATE system or no?
Shall I order along with your boards, 10 MCP170, 10 C2, 10 C3 to be sure to get my 9uA???
