Heltec WiFi Kit 32 to drive servo?

Has anyone succeeded in driving a small servo with this board? I can do it with other ESP32’s (“ESPRESSIF ESP32-WROOM-32”) that don’t have the display. If you got it to work, what GPIO pin did you use? I tried pin 14.

I’m an idiot. I had the pin# stickers on the wrong sides of the chip! Works great now.
