SparkFun MicroMod Cellular Function Board - Blues Wireless Notecarrier Shipping:4-6 Days These are Common-Anode type which

These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three legs to ground through a resistor

the shield effectively has a built-in MinIMU-9 v3 IMU module that can optionally be used to make a attitude and heading reference system (AHRS) so that your robot can its orientation

AX-18A has the same performance but more advanced external design than the AX-18F

It will also work perfectly with Arduino Mega R3's

The above schematic shows the additional components the carrier board incorporates to make the VL53L1 easier to use
