Scheme-it is an online schematic and diagramming tool that allows anyone to design and share electronic circuit diagrams. This is an area of the TechForum where you can ask questions, make comments, and share ideas about the Scheme-it tool. You will also find the answers posted to many of the frequently asked questions.
This Product Selection Guide contains information to help select products in the Thumbwheel Potentiometers category on DigiKey.com Thumbwheel potentiometers allow for manual adjustment of an in-circuit resistance value. Also known as thumbwheel trim pots, they are available in side or top adjustment and include a tactile edge on the actuator for human interaction and position indication. They ...
The Transient Voltage Suppressor (TVS) diode is a two-terminal semiconductor device designed to absorb a surge of electrical energy. They have a wide variety of applications ranging from input circuitry protection for Electrostatic Discharge (ESD) to “catching” the inductive kick (flyback voltage) of a relay. The TVS semiconductor is a unique device that clamps at a predetermined voltage ...
Introduction The Microsemi Maker-Board is a low cost evaluation kit featuring the SmartFusion 2 SoC. The SmartFusion 2 combines an ARM Cortex-M3 processor with Microsemi’s flash-based FPGA fabric on a single chip along with many of the peripherals SoC users are accustomed to such as RAM and DSP blocks. The Maker-Board adds on an Ethernet interface, an ambient light sensor, SPI Flash, and ...
Maybe drawing the schematic on larger paper, then printing with a reduction would be easier than trying to redo symbols? Mick Brian_German July 3, 2019, 6:47pm
This is an overview of how to build a latching relay circuit from a regular non-latching relay with the use of a few additional components. There are many other methods of latch circuits using digital logic, PLC’s, or the use of microcontrollers. Fig. 1 BOM Relay with a N.O. contact Voltage source matching the relay coil voltage N.O. switch (this can also be a float switch or similar N.O ...
My reference only: TT10141. Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to DigiKey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right ...
Figure 1: Schematic showing the typical PNP sensor to PLC interface. Tech Tip: The three-wire open collector configuration allows sensors to be connected in parallel using a wired OR configuration. You can find additional information about this type of configuration in this related post. While this is a valid configuration, the system will be ...
I stumbled across an opportunity and purchased about 300 of these damaged boards. They are PetSafe In-ground dog fence transmitters, model RF-1010. These have all been damaged by lighting surges. I am hoping that I can repair them and make some good money for my family. I know how to solder, but the problem is that I’m not familiar with this stuff, so I have no idea what these parts are or ...
