Inconsistent pinout TTGO LoRa T3-S3

Open BadCactus634 opened this issue 9 months ago • 2 comments

Hi, I'm trying to attach a BME280 sensor to my Lilygo TTGO LoRa T3-S3 that I just bought, but the pinout on the site is not correct. H594-PIN-DIAGRAM_600x600 As you can see, the pins of the I2C bus (SDA, SCL) are documented as pin 18 and 17, but these pins don't exist on the pinout.... where should I connect my I2C sensor?

SDA and SCL can be customized, and any unused GPIO can be mapped, for example

Wire1.begin(36 /*sda*/,37 /*scl*/)

Yeah but I can't do that, I'm using Meshtastic which do not allow for pin customization. Why don't just break out the pins from the display? It's connected to the same I2C bus....
