The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet (1MB pdf) before using this product.  
The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.)  
Ranging measurements are available through the sensor's I2C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output.  
The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.  
 
PIN     Description  
VDD  Regulated 2.8 V output. Almost 150 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 2.8 V input with VIN disconnected.)
 
VIN  This is the main 2.6 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I2C lines high to this level.
 
GND  The ground (0 V) connection for your power supply. Your I2C control source must also share a common ground with this board.
 
SDA    Level-shifted I2C data line: HIGH is VIN, LOW is 0 V
 
SCL      Level-shifted I2 C clock line: HIGH is VIN, LOW is 0 V
 
XSHUT    This pin is an active-low shutdown input; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. This input is not level-shifted.

The MAX7219 is an integrated serial input/output common-cathode display driver that connects a microprocessor to an 8-bit digital 7-segment LED display, or a bar graph display or 64 separate LEDs. It includes an on-chip B-type BCD encoder, multi-channel scan loop, segment word driver, and an 8*8 static RAM to store each data. Only one external register is used to set the segment current of each LED.
A convenient four-wire serial interface can be connected to all common microprocessors. Each data can be addressed without any need to overwrite all displays when updating. The MAX7219 also allows the user to choose whether to encode or not encode each data.
The entire device includes a 150A low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display 1-8 bits of data, and a detection mode that allows all LEDs to illuminate.
Only need 3 IO ports to drive 1 dot matrix! No flicker when the dot matrix is displayed! Support cascading!
 
Module parameters:
1. A single module can drive an 8*8 common cathode matrix
