    I have attached a block diagram. PCB board is having one power slot with 24V 40A. Other power slots (Nos 3-5) in the range of 10A. Mosfet load switches need to be designed to switch power slots. Also automatic power supply switching from main smps supply to battery supply need to be implemented. Project milestones are: 1. Project specification requirement analysis and finalization. 2. Schematic diagram and electronic BOM.

    I would need a quadcopter drone put together having motors, escs, battery, and so on without a frame, but mounted on a board. Everything would already be connected together and ready to go ,without the need for calibration, using a remote control at the flip of a switch. The battery would be at least a 6s, but preferably higher like 8s. The motors would need to be high torque and be as flat or least in height as possible. They would need to have the metal shaft already attached and preferably a threaded shaft. The bottom of the motor would preferably be flat too. There are no any specific measurements really, but the motors would be short in height like around an inch in height ,for example, and the motor shaft would preferable be 5 mm in diameter. The motors would preferable be under 500...

    Design pcb to house an esp32 module and associated electronics to make distance measurements from 10mm to 140mm. Accuracy within +/-10mm. The ultrasonic sensor needs to be mounted external to pcb via a connector. Do not want ultrasonic modules on pcb, u must design that circuit yourself. The esp32 will be going into deepsleep, so u must shutdown any current that will drain the battery. Pcb must accept battery holder. Deliver the following: pcb, schematic and libraries (kikad or eagle) Manuf gerbers Excelfile with bom (digiket, mouser or RS links)
