How to desolder
How to use
1.Place the desoldering wick over the solder to be removed,then put the heated soldering iron tip onto the desoldering wick.The solder will be absorbed.
2.Remove the desoldering wick after the solder has been absorbed.
3.Cut off the used section of the wick using nippers.
4.Repeat steps 1,2 and 3 if the solder is not removed completely.
Absorption may differ depending on the type of solder.Sn63% and 60% (tin content) have good absorption ability.

Usage Examples
How Much Power Does my Fridge Use - with the Battery connected to the SOURCE side and Car Fridge (or other accessory) connected to the LOAD side. The Watt Meter shows the current into the Fridge, voltage and power at the battery and accumulates the Ah and Wh while the fridge is running.
How much charge is going into my battery - With a battery charger (or alternator) connected to the SOURCE side and the aux battery connected to the LOAD side, the Watt Meter shows the charging current into the battery, the voltage and charging power at the battery and accumulates the charge (Ah) and energy (Wh) into the battery.
What is the output of my solar panel - With a solar panel connected to the SOURCE side and solar regulator connected to the LOAD side, the Watt Meter shows the charging current into the regulator, the voltage and charging power at the solar panel and accumulates the charge (Ah) and energy (Wh) into the regulator.
How much charge is my solar panel putting into my battery - Now with a solar regulator connected to the SOURCE side and battery connected to the LOAD side, the Watt Meter shows the charging current into the battery, the voltage and charging power at the regulator and accumulates the charge (Ah) and energy (Wh) into the battery.

2x16 Character LCD is most popular display component for small controller like Arduino, but most of these LCD uses parallel interface. In most of the cases, you will need 10 pins to control it or to display message on it. 8-pin are for the data, Enable and Latch pin for signal control. Minimum, you will need 6-pin for 4-bit mode interface. Still a lot of pins being used up :(
This I2C module for LCD will help you save all those precious pins. This module will only need 2 GPIO pins (specifically I2C pins) to send message to Character LCD.
This module uses an I2C communication interface. Including the I2C pins: SCL and SDA, it only require two more pins for power, VCC and GND. It saves 4 to 8 pins on Arduino or any other controller. The pins are breakout into standard right angle header (2.54mm spacing), you can connect with female jumper wires directly.
It comes with potentiometer for LCD contrast adjustment, and configurable I2C Address through A0, A1 and A2 pads. Anyway, the default address is 0x3F or 0x27. There is also a mini jumper to activate or deactivate the backlight.
- I2C connector: VCC, GND, SCL, SDA
- Compatible with Arduino/Genuino UNO, Leonardo, Mega, 101 (Intel Curie), Micro, Nano, Mini
- I2C Address:0x27 or 0x3F
- Supply voltage: 5V
- Interface:I2C/TWI x1,Gadgeteer interface x2
- Adjustable contrast via potentiometer
- Size:82x35x18 mm (3.2x1.4x0.7 in)
