Yes same thing happened to me here. In the hardware guide it says
"When power is applied to J1 or VIN, the external power must be in the range of 7 to 17 V. The power is converted to 5 V via a switching power supply, which powers the rest of the system. This supply was designed for a 1 A continuous supply. Higher currents will generate more power losses and may thermally damage the switcher. The switcher does have internal short circuit protection, and thermal shutdown protection. The end-user should not rely on thermal not short circuit protection."
Even though we were using correct power supplies, It seems like it maybe shorted, there was no shutdown involved with my incident so maybe it failed and just short circuited our boards or just had faulty boards. Now the J1 and my VIN do not work at all.
I just RMA'ed this thing. Ill see how round 2 goes.
