Scheme-it

Introduction

Schematic Drawings
Use schematic symbols to layout the components of your circuit and make electrical connections. With symbols ranging from amplifiers to vacuum tubes, as well as the ability to build custom symbols, you are able to design nearly any circuit. Access to Digi-Key's extensive part database also allows you to browse and assign orderable part numbers.
Diagram Building
Use the system blocks to refine your idea at a conceptual level. The higher-level components are there to help you plan out the broader intentions of your idea. This powerful block chain library allows you to quickly layout the function of circuit. Once your design is ready, save and share with your colleagues.
Flow Chart Creation
The flow chart creation option will help transition your concept to a design. Use the library of arrows, shapes, UML symbols, and more to sort out the flow and annotate each stage. Insert a textbox, math function/formula, image, or link to help illustrate the objectives and make your plan easy to follow.

The Wooden Menace-Robotic Arm

TE Connectivity's 2201855-3 I/O Connector demonstrates a reduced ¼ the size of a standard RJ45, which replaces the latter in robotic applications. It saves valuable PCB real estate and users have more freedom with smaller designs and additional port counts. The goal of this project is to create a robotic arm that can move in most any direction like a humanoid arm. It uses 2201855-3 as a connector for getting robotic commands from the microcontroller. It should have grippers on the end that can grip trivial objects like a piece of paper or a pen/pencil.

D-sub DB25 to USB Adapter

The DB-25 parallel port is a kind of connection for computers to communicate with another device. The port is also called Line Print Terminal (LPT) because it is usually designated as printer port. Through innovation, this kind of port becomes obsolete due to its physical design; thus, the Universal Serial Bus (USB) interface has replaced the parallel printer port. The size matters for new computers, which eliminates the use of D-sub connectors.

Industrial C-slot Cylinders with M8 Connector

There are different types of environment that can be expected to industrial plants. Since dc/ac motors and other mechanical equipment are common to these areas, mechanical wearing with vibrations is also expected. This vibration is natural to mechanical equipment even in a small frequency but enough to cause problem to small signal devices like sensors. The sensors should be durable that meets the standard requirements. Other than sensors, the system should also have a secure connection in which TE Connectivity M8 connectors can provide the rest of connection requirements. In this design, it shows a simple automation of flow control. It makes use of actuators and magnetic sensors that securely integrated to its electronic control unit using and M8 connectors. The M8 connector offers the safe and reliable connection with flexible and high temperature thermoplastic design. Its gold plated or brass contact with shield of steel or nickel-plated ensures the efficient flow of data and low power source.

RJ45 Modular Jack Connector with Pulse Transformers

A Registered Jack 45 (RJ45) connector is a standard type of connector for data communication that is commonly used for Ethernet cables and networks. The RJ45 connector is a modular plug used primarily for network cabling. The connector features eight pins to which the wire strands of a cable interface electrically. Standard RJ-45 pinouts define the arrangement of the individual wires needed when attaching connectors to a cable.

Simple Ham Radio Bluetooth Interface

Ham radio is a popular hobby and service in which a licensed amateur radio operator explores communications equipment. Typical ham radios do not have bluetooth support, which may be hassle for some. None of the transceiver manufacturers are providing a wireless interface. However, with this ham radio bluetooth interface, communicating and listening to other entity would be easier. The device uses Bluetooth module and a circular connector. The TE's CeeLok FAS-T connector is one of the most rugged, small, 10 GB Ethernet, field terminable I/O connector. It has been designed to perform in some of the most extreme environments in the industry, while providing substantial size and weight savings via its small shell size 8-form factor.

Stacked PC and PC/AT Architectures

The PC and PC/AT architectures have ended up amazingly popular in both general purpose (desktop) and dedicated (non-desktop) applications, its utilization in embedded microcomputer applications has been constrained because of the expansive size of standard PC and PC/AT motherboards and extension cards. The circuit uses the TE 1-2201197-0 fine pitch, surface mount, stacking connectors as the interface for each module.

Peripheral Slot Card for CompactPCI Serial Systems

This project is designed with TE Connectivity's backplane connector 2198265-2 to support the 14 GbE ports of the Peripheral Slot Card for CompactPCI Serial Systems. PCI (Peripheral Component Interconnect) is an interconnection system between a microprocessor and attached devices in which expansion slots are spaced closely for high-speed operation. With the integration of the STRADA Whisper connector, it can transfer data at blinding speeds of 25 Gbps and offers unparalleled scalability up to 40 Gbps, which allows achieving efficient future system upgrades without costly backplane or midplane redesigns.

High Speed Serial Link using Strada Whisper Backplane

This design shows a high speed serial link using Strada Whisper Backplane. Serial link is a type of communication between two digital systems wherein data is transmitted as a series of voltage pulses down a cable/wire. Amid the world's growing data needs, data transmission speeds need to increase as well. The greatest challenge is that data rate has to be faster while maintaining or lowering the rated power. Connectors are very fundamental components to consider in the design. Lossy connectors would damage signal integrity. Signal integrity is the key: without it, systems don't run cost-effectively. To make these connectors fast and reliable, TE Connectivity has integrated some features to increase signal integrity.

High Speed Parallel Backplane System Interfaced for Plug-in Cards

Data transfer rate has a vital role in data communications. Every network application needs a certain amount of data to function effectively that makes high data transfer rates beneficial in modern business networking. A backplane system such as the TE Connectivity's STRADA Whisper connectors are widely used in computer and telecommunication systems because of its revolutionary design that transfers data at a rate of up to 40Gb/s. It is the first of the next generation of high speed interconnects with extremely low noise characteristics allowing data to run at longer distances. Thus, permitting networks to be used for complex tasks while slowing the traffic.

High Speed Data Communication Management with Strada Whisper

The technology advances a lot after mobile phones are commercialized. The mobile phones provides remote communications and data transmissions at very convenient way. With these ease of data communications, it is now possible to collaborate ideas and innovations around the globe. The data transfer requirement increases accordingly because of the number of users that needs to communicate and exchange information every now and then. Therefore, the communication system needs to upgrade in order to meet the demand in information technology. In this simple design is built a STRADA Whisper backplane connector that offers a data transfer of 25Gbps and scalability up to 40Gbps for further future system upgrades. It has an insertion loss of less 1dB and linear up to 20GHz. It has individual shielded pairs offer excellent signal integrity / EMI performance that makes it less susceptible to noise and resulted to greater flexibility.
