heltec LoRa32 v3 and sht30 hookup

Here is a Heltec Lora32 V3 module with two extra pins added to the board to give easy access to the i2c SDA and SCL pins for Environmental Sensing in Meshtastic firmware. Pin 17 is SDA and pin 18 is SCL. I tinned the two pads on the circuit board with silver bearing electronic solder and tinned the tips pf the two pin male header and, using the "helping hands" jig I soldered the pins to the board. Using the Meshtastic web flasher (flasher dot Meshtastic dot org) on an Opera web browser on Linux, I flashed Meshtastic 2.2.23 and then, using the Meshtastic android app, I scrolled down to the "Module Configuration" section and clicked on "Telemetry" and enabled the "Environment telemetry" and enabled "Displayed on screen", etc. And it WORKED! Even though the SHT30 sensor is on the same i2c bus as the OLED display, it did not mess up the OLED display. If I probed the i2c pins with a voltmeter, it messed up the display.
