GPIO Reference Board (Model B+,A+,2B and 3B) (1C3 gpio ref 40pin board)
RASPBERRY PI NOT INCLUDED(Neither the key-ring and keys for those who wondered)
This cute little GPIO reference board from allows you to quickly and easily distinguish between the different pins of the Raspberry Pi Model B+, Raspberry Pi 2B, Pi 3B and Pi 3B+. It's even got a key chain hole, so you can carry it around and keep it handy - you'll never know when you need to hack a Pi!
The GPIO reference board features BCM numbering on one side and the pin names on the other. It can be soldered for permanent referencing, or slipped on and off when required.
Dimensions:
Width = 67mm
Height = 19mm
Thickness = 0.8mm
On the RPi3 and later you'll have to snip off a little bit of the corner closest to pin 39 thanks to the new POE pins on the board

130A High Precision DC Watt Meter And Power Analyzer (1A2 DC Power analyzer)
Examples of Uses:
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.

FAQ
Why is the test data wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?
Answer: There are three types of power:
Active Power (P represents / unit W)
Reactive power (Q represents / unit Var)
Apparent power (S represents / unit VA)
Here we only talk about Active Power, for others, please google it:
P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P<U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor.
