Hi All,

any idea why this product won't boost the 3.3V 2Khz pwm signal from the Atmel Xplain PRO board? It's set up correctly, GND from the XPRO, 5V from XPRO, 3.3V from XPRO, input from PWM signal, but only output 3.3V .. i have measured all lines with the Oscope and tried 2 different boards (i.e. i have multiple copies of this product) https://www.sparkfun.com/products/12009 and all that is output is a 3.3V pwm.

LV GND = GND
LV = 3.37 V
LV signal is 2khz
HV = 5V
HV GND = GND

So lost why this is not working, any help would be great. Thank you in advance...
