VEXT and Voltage Divider

#1

Just to be sure I am not soubling up with voltage dividers i take it on the Wireless Shell there is no voltage divider on pin13?

Also If i have my sensor powered from Vext in my code i send pin 21 high or Low to either power it or turn it off. Is this correct?

Yes, there is no voltage divider on GPIO13.

Vext is control via GPIO21, it’s already included in the module.

When GPIO21 is HIGH, Vext have no output; GPIO21 is LOW, Vext output 3.3V
