...prototype parts. In this case, the price of a large batch is not very important, but how to get one or two pieces quickly and reasonably for testing. The main work is to ensure that the parts have the necessary features and that they actually work. For example, we currently need a PowerBank + trigger-USB cable that supports PD/QC fast charging, so that we can get power out of both 5V USB cables and 12V USB cables, with sufficient amperage in both. A test batch (5-20) means that we are looking for a good supplier from whom we can get a high-quality large batch at a low price. If the test batch works well, we will move on to making 50-500 piece batches. Larger batches are redesigned separately. We primarily use Alibaba, especially when making test batches. We make larger purchases ...

i have 60 12v motors (they have own board with some protection) , which i try to control from arduino im doing now with a 679 darlington transistor but there are lot of cables, i try to make things simple and i need to design a pcb like this in image (atachment) i want to add there RJ 45 port and add motor wires to it for simple connection. i need to do it via any cheap online platform like JLPCB or similar

The aim of this project is to design a power supply that can generate 0-10V and source a current of 6A, has a small size and has a low number of components. The input of this supply would be derived from a 12V source. The control of the Power Supply is open for discussion. It can be based purely on software (digital communication between this PCB and the control PCB) or voltage-dependent feedback (ADC/OpAmp based on this PCB, with the control signal generated on the control PCB). The input 12V is biased at -40kV, and therefore this PCB will be floating at a potential of –40kV. Any mode of communication that is not affected by the fact that this PCB would be floating at –40kV can be implemented. Please discuss the approach to establishing communication a...

I need a circuit design & fabrication of a prototype unit to limit and dissipate high voltage spikes on a 600 VDC, 3.5 kW power system. A small wind turbine on my farm produces up to 3.5 kW, 600 VAC,3 phase power at wild AC frequency (0 to 200 Hz?). A full bridge, 3 phase rectifier takes the wind turbine output & generates 0 to 600 VDC, single phase, single leg, at varying amps, with some noise. If the rectifier output voltage exceeds 300, 400, or 500 VDC (switch selectable), the rectifier engages a load dump heater to dissipate excess power and control maximum voltage output. The rectifier's DC output is fed to a Morningstar Tristar MPPT Charge controller (Model: TS-MPPT-60-600V-48) so as to charge a 48 VDC battery bank. This $2,000.00 Tristar i...

...There are two high voltage LM2596 buck converters that make 12V for a string of LED lights on one one node, and 5V that powers the ESP-32s and servo for another node. Communication between nodes is provided via CANbus using a 3.3V CAN transceiver (ESP-32 has CANbus available, just needs the addition of a transceiver chip: SN65HVD). The CANbus is working fine throughout. However, when I power the network and connect the nodes, I am frying the ESP-32s. I verified that the 5V pin on the ESP-32 is indeed only getting 5V so it is not being overdriven there. I am trying to figure out why the ESP-32s are failing (they get very hot and eventually (a few minutes) die miserably). I've attached the PCB schematic. I'd appreciate any help with design but mostly need to figure...

I need an over voltage protection circuit designed, which needs to cut off the input source when it reaches 59vdc. Max current of power circuit is 3amps. This is to protect the 12v and 5v power regulator circuits. During normal operation, the input source is between 40-59vdc. There are situations that arise where the input voltage may rise to 160vdc for about 3-4 seconds, hence the requirement of over voltage circuit to protect the regulators. The circuit must fit in an existing pcb design. Parts must be available in Jlcpcb. I want the circuit built and tested before payment

i need a pcb board for solar lamp project of 12V

We are a company that produces...does not charge the battery fast enough. We would like to replace this with a dedicated li-ion charging circuit which can supply up to 1A, from a typical "12v" (up to 21v) 50W solar panel. The task will be to design a schematic. We will incorporate the schematic into our main design and we will do the PCB layout. You will need to choose components from the JLCPCB catalogue. Using the EasyEDA design platform will probably be easiest for integration to our project. The output of the task will be a schematic and a BOM, with secondary part options for each primary component (to be used if stock levels of primary component are low). The design will need to be compliant to UKCA and CE standards for EMC interference,...

...each distinct voltage(12, 24, 400, and 700). So it is overall a 5 week project for completion of the entire design, with 1 week deliverables for each voltage. i.e. week 1: 12v design delivered; week 2: 24-volt design delivered, etc. The additional week is for periodic reviews and finalization of the design. Salary will be contingent upon experience and will be discussed with prospective candidates. It will be no less than $1000 USD per week, again negotiable based on candidate experience. This is an opportunity to work on an innovative and distinct project, and the possibility for further contracts with us will follow upon successful and satisfactory completion of this design. We encourage you to apply to find out more details abo...

...Currently there is a piece of plastic that spins around on a shaft, hit hits two manual contact switches depending on which way it is spinning. This is not a good design as each time it hits the switch it 'slows' it down from spinning. So we want to redesign this system as basic as possible using a 3D HALL SENSOR. So it detects the spinning, which way it is spinning, then triggers opto isolator output depending on which way it is spinning, clock wise or anti clock wise. New circuit board will - Detect spinning - Detect clock wise or anticlockwise - Send output depending on direction to an opt isolator. Board Design should include. 12v Input(marked +, -) 3 pin output (opto isolated), (white violet, white blue and green black(has diode). Output '...
