@Shivanand-Chanderbally I recently finished a node using the acs712 and found it to be very sensitive to nearby magnetic fields. It is best to have it as far away from these as you can.

Unfortunately we do not have any other manufacturing partners, so all sensebender boards are produced by itead.
How did you confirm that the board where broken? Have you tried starting the self test in the standard firmware that the micro is delivered with?
The factory firmware is available at
