OpenGD77

I know about that pin, but there is no PAD for it. What append in case that regulator get shorted for whatever reason, do you thing the MCU GPIO will survive ? On EN leg is only pull up resistor and LP3992. In your scenario fault may can short to ground or pull to 3.3 from regulator gd77. In my cas...

The power control is done using a N-Channel MOSFET (AO3400, cheap and I have plenty), and 2 resistors (300kΩ between Source and Gate, 200Ω on the Gate line). I use to Power Control for GPS built in voltage stabilizer in GP-02 Kit. Small chip LP3992 have a ENABLE leg. So i connected to CPU and seems...

I really Thank You for guide how add GPS to GD77
I have question, bold satellite number is for Beidou system?
