This module is a portable mobile power supply that supports 3V / 1A and 5V / 2.2A two kind of voltage outputs.
5V voltage output rated current is 2.2A, maximum support 3A current (not recommended for overload, easy to damage the module, speed up the service life), the output of current depends on the quality of the 18650 battery.Micro USB/Type-C charging current 600mA-800mA, supports up to two 18650 batteries. It is recommended to use two 18650 batteries, which can be longer.
Special attention: the installation of the battery must be determined positive and negative, the board has been clearly marked positive and negative! Installation errors will burn out the module.

The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. 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, lead less, 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 micro controllers 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

Solderless and crimpless, all you need is just a heat gun to finish the joint, much faster and easier than the old way.
Fit for Confined and Narrow Spaces - can be bent after connection and no need to crimp or solder in the confined area, just control the temperature via a heat gun.
Better Waterproof and Seal Performance - there is two hot melt waterproof adhesive rings in each butt connector, which help it hold up better to moisture.
High Temperature Resistance in A Short Time: use exclusive material in the butt connectors to avoid shrink tubing melting before solder ring.
Shrinkage ratio is 3:1
Temperature that start to shrink: 80℃
Temperature that solder ring start to melt: 111˚C
Temperature that solder ring melt completely：138˚C
NOTE: Temperature of surface of the connector is what is mentioned above, rather than the temperature that the hot air gun should set.

The new Raspberry Pi Zero Wireless is an super-ultra-low-cost, tiny-small-form-factor Raspberry Pi! It has WiFi and on board Bluetooth for better connectivity.
BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in I2C.
This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!
The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. For simple easy wiring, go with I2C.
Supply Voltage: 1.8 - 5V DC
Interface: I2C (up to 3.4MHz)
Temperature: -40 to +85°C
Pressure: 300-1100 hPa
SDO LOW : 0x76
SDO HIGH: 0x77

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins!" Are you out of luck? You would be, if you didn't have this ultra-cool TCA9548A 1-to-8 I2C multiplexer!
Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command.
Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77) and you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets will get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part.
Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level.
This is Dot Led Matrix Module incorporating MAX7219 Driver chip. By using this dot LED module in your upcoming project, you will be able to add some great cool animation.The individual module features 32×8 LED’s, each controlled very precisely by the MAX7219 driver to generate the color pattern you wish. The great advantage of using this is users will have control over all of the 256 LED by just connecting 3 output communication wires to microcontrollers like Arduino etc.
