Esp pcb with integrated ultrasonic distance measure
Budget: $30 – $250 USD
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)
