If you selected the components what you will use, it's time to assemble. The PINs in ESP can be changed if you compile the firmware yourself.
- ESP Serial RX (for GPS) PIN 6
- I2C SCL -> ESP PIN 4 i2C SDA -> ESP PIN 5
Line the GND to the module's GND, and 3.3V or 5V according to your module to the VCC of your module. The GPS TX pin should be wired to ESP's PIN 6. GPS RX not used.
Line the GND to the module's GND, and 3.3V or 5V according to your module to the VCC of your module. Wire the module's SCL pin to ESP PIN 4, and SDA pin to ESP PIN 5.
With I2C devices you must use the same SCL, SDA pins for all devices you want to connect.
