My team member bought Micromod teensy board and SparkFun MicroMod ATP Carrier Board a few days ago.
He bought 60 Micromod teensy boards.
Today, I tested these boards but 9 boards didn't work.
These didn't blink led STAT, and It coudn't find serial port in my computer.
51 boards are working correctly, but 9 boards are not working.
Is this a problem of hardware?
my order numbers are 6719700 and 6681687.
