I got BME280 boards a little different (wider) then this one: Bme280 - Hardware details | Soldered Documentation
I power it directly with ESP32-S2 3.3V
I get that I need to cut JP3 and short JP4 to get the VCC from the easyC connect to VCC from the jumper wire, but what about SDA and SCL? How to short them between easyC connectors and header breakouts?
A schematic of your board would help.
