Revolution Pi Analog I/O expansion module (RevPi Analog I/O)

Using the analog I/O - module RevPi AIO your RevPi base module can be expanded by 4 analog inputs, 2 analog outputs and 2 RTD input channels. This expansion module is connected to your base module by the means of the overhead PiBridge plug. Inputs, RTD inputs and outputs are galvanically isolated to each other. Differential inputs eliminate ground loops.

Analog input range/options: +/- 10 V, 0 – 10 V, 0 – 5 V, +/- 5 V, 0 – 20 mA, 0 – 24 mA, 4 – 20 mA, +/- 25 mA

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.

25A MOSFET High Power Heated Bed Expansion Power Module MOS Tube for 3D Printer (2 units) (3B6 twin Mosfet board 3d print)

This module is based on power MOSFET and will allow PID control of the heated bed (DC-DC Relays usually do not allow this)
If your total power usage is 240W, and you have a 12V power supply, that means at least 20A (20X12 = 240W) is required.
Since the controller board can only set 15A, this setting will not work. To make it work, you need this extra power module.
Under normal cooling conditions, the module found stable operation with I(Max) = 25A, and the current used should not exceed 25A.
If you plan to use a heated bed with a 3D printer that uses a 12V power supply, this module is recommended for you.

- Universal heated bed power expansion high power module for 3D printers.
- Can be used on Chitu motherboards and other open 3D printer motherboards.
- Helps 3D printers equipped with controller boards (up to 15A) become even more powerful.
- With this additional module, the maximum current on the board can reach 25A.

1. Colour: Black
2. Maximum current: 25A (enhanced heat dissipation)
3. Size: about 6 x 5 x 3.1cm 
4. Mounting holes: 3.2mm diameter, for M3 screws

--100 MHz (typical) shift out frequency
--8-bit serial input
--8-bit serial or parallel output
--Specified from -40C to +85C and from -40C to +125C

Typical Application:
--Drive a lattice screen
--Driver numeric display
--Drive matrix LED

How to Use:

Insert the module that the silk screen says 'RPI IN'. Pay attention don’t make the direction reversed! The correct direction of insert module is above the Raspberry Pi’s PCB; The 8*4header in the module are Q0-Q31 expanded GPIO, they can connect to the peripheral through the Dupont Line. The header which near silk screen write 'EXT' expand GPIO of Raspberry Pi, user can cascade the other module or the same module.

Package Includes:

1x Raspberry pi IO expansion board

IIC/I2C/TWI/SPI Serial Port Module 5V 1602LCD For Display (IB4 serial adapter board)

This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
I2C Address: 0X20~0X27 (the original address is 0X20,you can change it yourself)
The backlight and contrast is adjusted by potentiometer
Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
I2C Address: 0x27 (I2C Address: 0X20~0X27 (the original address is 0X27,you can change it yourself)


Compatible for 1602 LCD
Supply voltage: 5V
Size: 5.5x2.3x1.4cm

Package includes:
1 x serial interface module
