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.

Discontinued: Raspberry Pi Compute 3 Module I/O Dev Board (AW C2 Compute 3 DEV board)

The Compute Module 3 I/O Development Board (CMIO V3) is suitable for the development of Compute Module 3 or Compute Module 3 Lite. The IO Board features an SD card socket to support the Compute Module Lite 3 variant and breaks out the compute modules I/O's to various ports and 120 x standard pitch 0.1" headers.

To start the development, plug the Compute Module 3 or Compute Module 3 Lite into the IO Board, and power the development board using a micro USB 5V 2.5A Raspberry Pi Power Supply. The development board contains all of the necessary interface ports to allow an engineer to design and test their own prototype application. The modules simplify the design process engineers need to undertake when developing a System on Module (SoM) solution into their final product. Engineers do not need to concern themselves with the complexities of interfacing with the BCM2837 processer directly and instead can concentrate on designing the interfaces to their own IO board and their application software . This simplicity fosters rapid development.

Please Note, this is the IO Board only, compute module is not included.

The Raspberry Pi Compute Module I/O Dev Board Features the Following Interfaces:

  • Multiple GPIO interfaces on 2 x 60 way 0.1" Headers
  • 1 x Micro USB connector type B - USB Slave
  • 1 x USB connector type A - USB Host
