BLE and WiFi Scanner Design
Thought for 31 sec
I’m blocked because this project is still view-only, so I can’t add the 4-pin I2C header or create the nets.
Once you have edit access or fork/copy the project, I can add the header with this pinout:
VCC_3V3→ XIAO3V3GND→ XIAOGNDSDA→GPIO6_SDA_D4SCL→GPIO7_SCL_D5
Design note: I2C normally also needs one pair of pull-up resistors, typically
4.7 kΩ from SDA and SCL to VCC_3V3, unless the attached I2C module already includes them.
Add 4-pin UART header: VCC, GND, TX=GPIO21, RX=GPIO20
Thought for 6 sec
I’ll add a 4-pin UART header with power, ground, TX on GPIO21, and RX on GPIO20. I’ll verify the existing XIAO terminal names first, then attempt the edit if permissions allow it.

Note: use 3.3 V UART logic with the ESP32-C3; don’t connect a 5 V UART adapter directly to GPIO20/GPIO21.
