I just finished porting the code to run on an Atmega328p. This means that we can now use standard Arduino boards (UNO, Nano, Leonardo...) 

For a question of integration in the box, I rather recommend using the NANO board. 

#if defined(TEENSYDUINO)
#define TOF_SDA 18
#define TOF_SCL 19
#define VL53L1X_1 17
#define VL53L1X_2 16
#define VL53L1X_3 15
#define VL53L1X_4 14

#elif defined(ARDUINO_SAMD_MKRWIFI1010)
#define TOF_SDA 8
#define TOF_SCL 9
#define VL53L1X_1 7
#define VL53L1X_2 6
#define VL53L1X_3 5
#define VL53L1X_4 4

// #Arduino UNO, NANO, Leonardo...
#else 
#define TOF_SDA A4
#define TOF_SCL A5
#define VL53L1X_1 A0
#define VL53L1X_2 A1
