I probably take GRHVxxx fully assembled. High voltage + tiny smd = high probability of burned pcbs. I have a hot plate and can do smd soldering. But I am pretty sure that GRHVxxx is two-sided, and requires hot air or an oven.
According page 7 of the LSK389 datasheet, LSK389 comes in 4 different versions (A to D):
IDSS Range (mA)
A 2.6 to 6.5
B 6.0 to 12.0
C 10.0 to 20.0
D 17.0 to 30.0
Which version of LSK389 is needed for Blue Hawaii?
