    I need to design a board with esp32-pico-mini-02 and two L6470h ST drivers to drive two 12v Stepper motors. The board must be as small and compact as possible and work at 12v and the controls to the motors must be read via rs485 or rs232 interface of your choice via micro selector. For more details after the acceptance of the work.

    I am a furniture maker and I am currently building a wooden drinks cabinet. The cabinet is 450mm tall (low coffee table height) and I want to have a lift mechanism that will raise and lower a drinks shelf. There is not much room to allow for linear actuators, so I have sourced a mechanical scissor lift which goes from 95mm (fully closed) to 370mm (fully open). The lift is designed to lift motorcycles so it is very strong, but it is operated manually. It has a hex nut which drives a threaded bar. Using a socket and wrench, the operator can manually lift and raise the scissor lift. I am looking for someone to help me automate this lift process. I want the operation to be silent (no high pitched sound of electric motors). I want to control the speed and distance of the lift and for the lift ...

    I don't have a file for my project, however I do have an example of what it is I am after and I also will do my best to provide a list of additional things need to be optioned/added to my example file to best satisfy my project's requirements. I am aware the circuit is very basic but I am more inclined towards the PCB for the space saving aspects than anything. All of the circuit components must be rated for 12VDC @ 10-15A. My circuit will be very similar to the attached file (nearly identical in design, as I have an all analog/some breadboard version of this proposed idea currently operational on my vehicle) with the addition of fused power supply outputs to the electronic ignition system, accessory power, both of which would be relay switched power feeds directly from the batte...

    I have designed a PCB that is powered by 12v. It powers an esp32 cam, attiny chip and PIR sensor with a 5v buck convertor. I have added a circuit to the board for a "dark sensor" utilizing an LM393 chip, that will allow the main 12v current to flow when sun goes down. I need someone who is an expert with circuit design, to check and verify the "dark sensor" portion of my circuit, even though this is considered a relatively basic design.
