I need help with design of a device which can take DC (variable voltage as input from 12-60v) and convert that into an AC 110 volt 60 Hz (also 220 volt 50 Hz) and such device should be able to sense voltage and frequency of the grid , where we are trying to feed , and based on that, it can synchronize frequency and voltage. And then it can feed power to the grid, but say from usual household plug so that it becomes portable device for say uto 1000 Watt portable solar power generators, wind generator. If output voltage sensing is difficult then probably 2 models - 110volt 60 Hertz and 220volt 50 Hertz. Also need a prototype shipped to me to US, along with all the schematics, drawings, designs.
I plan to use a TPS54283PWPR from Texas Instruments in a project I am working on. I need an experienced engineer to help design my schematic and to ensure I have not made any silly mistakes (before I commit to the PCB) - alternatively, if this proves to be the incorrect part I will need help to identify alternative. All I need is a reliable DC DC converter with 24vDC input and output 1 = 5v at about 2 amps and output 2 at 3.8v at about 1.5 amps (I'm struggling with the maths in the datasheet)
I am currently developing a battery powered DC variable power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for re...
It is a probe card with simple components like Resistors and Caps and LDOs and some switches. There is one BGA component microcontroller and we need somebody to come onsite and help with testing/soldering rework as and when needed.
Looking for Altium PCB design professional, who can design PCB from the schematic, and prepare the BOM list for the SMPS power supply. Since it is 400V DC applications, the PCB should design suitably in professional way.
Looking for PCB designer Professional in Altium Software upto 8 Layer PCB. The partial work has been done the pending to be done.
Seeking a remote solar PV design specialist to work with company providing turnkey solutions. We would require both illustrative design of system array/s and ideally electrical schematic. You will be provided with a BOM from which a Solar Array Design (including sight of the space in which to create)and the Electrical Schematic will need to be created. In addition, calculations relevant to system production, along with load consideration on the electrical side are required
I'm looking for an electronics expert to help me work out how to automate functions on a circuit board. If you understand the attached board and how it works message me for further details on exactly what I'm looking to do.
Hello, we need a complete PCB design and component selection. for a camera battery charger. there will be 3 Batteries of Sony camera see image for details. Device should have display to show charging percentage of each battery. we need a professional person for this project.
Looking for an embedded engineer to design an IR remote control receiver to adjust the volume, select different inputs, power on/off ,tone control bypass for an audio amplifier / preamp Please read complete attached scope of work before submitting your quote Will be helpful if you can share reference of past experience of similar projects
We require a PCB designer to layout a PCB for us. The test circuit has been developed on an STM32 Nucleo-144 MCU Development Board, NUCLEO-F767ZI. You will be required to draw the full circuit based on the development board and then after approval, layout the PCB in accordance with the circuit diagram. I am reposting as time got away with me late last year. Want to award by the end of the week. PLEASE READ THE ATTACHED DOCUMENT. IF YOU DON'T READ I WILL DELETE YOUR BID.
Hi! I basically need from you to build PCB for prototyping purposes (design that could be easily and very quickly manufactured). I have around 30 micromotors from 1, Constar company and this connector: HRS DF36-15S-0.4V(51) 2, I also have few Maxon "Heavy duty" motors and 3, Flexible PCB with many sensors. PCB should enable connection from above appliances into many motor drivers and controlling boards. Additional requirement is that this PCB should enable us to have extremely fast signals as the whole prototype works on CAN FD with controlling loop 2ms. *Prefered skills in high speed robotics or automotive industry is needed. Please do not apply if you don't have advanced experience. FAQ: 1, When do you need it? Ideally yesterday, acceptable this weekend, negotiable one...
