    I would need a quadcopter drone put together having motors, escs, battery, and so on without a frame and sent to me. 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 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.

    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)
