Hi everybody,

Having issues with the GPS Module. It pretends to be dead. No more response 
whatsoever. I'm now going to 
try and do a hardware reset, but in order to do that i'll have to figure out 
what this means;


As with ANTARIS 4 versions, LEA-5 and TIM-5H modules come equipped with a 
RESET_N pin. Driving RESET_N
activates a hardware reset of the system. Unlike ANTARIS 4 modules, RESET_N is 
not an I/O with u-blox 5. It
is only an 
input and will not reset external circuitry.
Use components with open drain output (i.e. with buffer or voltage 
supervisor ).
There is an internal pull up resistor of 3k3 to VCC inside the module that 
requires that the reset 
circuitry can
deliver enough current (e.g. 1mA).
Do not drive RESET_N high.


What is this trying to tell me? 
"Driving it low"... like holding it low when loading a bootloader onto a tiny?
Any help appreciated.

Best regards,
