A first raspberry pi project. Pin11 is green, Pin13 yellow and Pin15 is red. Pin 19 is connected to a momentary switch. Many thanks to the developers of Scratch.GPIO who made this so easy to do. It was Peter's first attempt at a hardware project and also his first Scratch project. The resistors are 330ohm.
The PmodPS/2 is a module that allows users to interface PS/2 style mice or keyboards with their system. By supplying a clock signal to the Pmod, users can then receive the standard 11-bit words that are sent from the attached peripheral.

The BerryClip is a really nice little addon board for the Raspberry Pi which sits on the GPIO pins and provides a switch, 6 LEDs and a buzzer. Available online.
The PmodR2R is resistor ladder with a R-2R resistor configuration. Users can provide 8-bits of parallel data to the module through GPIO signals. This setup teaches users the basic principles behind a Digital-to-Analog Converter.

The PmodSTEP provides a four channel drive for a stepper motor via the ST L293DD. Users may wire two pairs of channels in series to drive up to 600 mA of current per channel and can view the current status of a GPIO signal through a set of user LEDs.
High performance and affordable, Camelot Camera series is the first USB2.0 smart camera system that features a stackable design and customizable features.
This Camera series and other were developed by Imaging Diagnostics, a leader in embedded imaging systems.
Having established that I could get GPIO output working, I've added a switch for input. This enables me to switch between different flashing patterns for my set of LEDs.
The PmodKYPD is a 16-button keypad arranged in a hexidecimal format (0-F). By digitally driving a column line to a logic low level and digitally reading each of the rows, users can determine which button is currently pressed.

The PmodCON3 is a module designed to connect up to four servo motors. Users can control each of the motors individually through GPIO as well as powering them from an external power source.
The PmodLS1 allows users to communicate through GPIO signals with up to four optical sensors. If a reflective infrared light dectector is used, a line following robot can easily be created.
The PmodCON1 is a small module with six screw terminals to interface with external wires that are not compatible with the DIP standard. Two of the terminals can be used to provide power from an outside source and the other four can be used for data signals.

How to test an android LCD screen?How to test an android LCD screen?
We are committed to promoting Android screens and hope that more and more engineers can experience and test the Android LCD module by themself, and it will be found that Android LCDs can greatly optimize devices' human-computer interaction experience.
If you haven't used Android screen or similar products before. We recommend that you first read our product specifications and development manual. Our sales team will recommend relevant models to you according to your needs. After you purchase samples, relevant development cases and SDK will be shared with you. This will help you develop your own functionality.
You can learn what functions our screen can support from our specifications. Usually, our modules support Android 5.1 or higher systems, and Proculus is able to provide clients with customized operation systems, such as modifying boot animation or customizing boot software. In addition, various interfaces are reserved on our PCB board, such as serial ports supporting RS232 and RS485, IIC, HDMI, and GPIO. If you need audio and video, we also reserve interfaces for microphones and speakers.
On this basis, if you find that you still cannot meet your development needs, you are welcome to put forward specific needs to our sales personnel, and we will provide specific customized development services according to your project needs.
Can I customize a LCD?Can I customize a LCD?
Proculus Tech can help clients customize LCD Modules according to industries requirements.
If you need customized service, please let us know:
1. What is your EAU?
If you don't have a mass production plan yet, we will try our best to find a standard product that is suitable for your application. Custom service often means re-design and new mold creation, which might not be economic for your project. But we will provide custom service if you're sure to take the development cost.
We’re glad to see our partners to be price competitive in the market. Proculus is going to refund development cost when the project goes into mass production and place order more than 500 units.
2. Hardware Configuration?
Please check the standard product specifications first and let us know what changes you want:
a. Amount/type of interfaces
b. PCB layout
c. The PCB size
d. LCD brightness
e. ouch screen size/type
f. Other external devices
3. Do you need us to develop software?
We can help you develop Android apps to implement the functions you need. Please describe your needs in detail to our sales team, we will assess the development time and cost accordingly.
If you have more questions, please send us an email to: contact@proculustech.com
Why Choose Android LCD Module?Why Choose Android LCD Module?
When people talk about human-computer interaction, Android module often plays a very important role.
At present, the mainstream interaction mode can be divided into Android and Windows according to system type, and can be divided into tablet integrated mode and chassis mode according to form.
So what are the advantages of industrial Android tablet modules?
1. Android module is small in volume, easy to install and maintain.
2. touch function can simplify the work, more convenient and fast, more humanized.
3. It integrates main board, LCD and touch screen into one module, has good stability.
4. It doesn't need fan for heat dissipation, so that has a smarter volume than industrial computer. The use of aluminum block heat dissipation in the shell making lower power comsumption and low noise a reality.
5. In addition, Android is widely used and has a good development foundation.
Proculus Tech has common advantages in Android industrial tablets, and has been widely used in industrial, medical, chemical, smart-home, manufacturing and other work areas by users. Today, Proculus smart industrial tablets are widely known in business. Coupled with the growing need for smart shopping malls, Android industrial tablets can be better connected to mobile terminals, and its advantages will gradually emerge. This will also bring great convenience and practicality for the intelligent management of the industrial site.

The PmodDHB1 uses the Texas Instruments® DRV8833 dual H-Bridge motor driver chip to drive two DC motors or a single stepper motor. Each H-Bridge can be driven by GPIO signals.
Mounted the GPS receiver to the Pi using velcro on the battery holder so I can remove it if needed. This case has a nice opening to facilitate access to the GPIO pins.
This picture shows the test setup used to test with a 30 MHz SPI bit rate which is the maximum supported by the NXP LPC214x microcontroller used on the SPI master board (USB13700 board with it's GPIO API).

This hardware disconnects the Home Assistant Raspberry Pi from wall power when a nearby severe storm is detected. The RPi is not shutdown, but is forced to switch to battery backup power by removing power from the UPS input.
The RPi itself controls the power by GPIO pin controlled by an automation in Home Assistant.
