I need a circuit schematic for the 'active' probe end of a 4 probe EMS / TENS device.
Award will be provided to best and most reliable configurable and controllable circuit.
I have seen many circuits online, but I want one to that I know is most configurable and controlled by the output of a microprocessor. inputs can be just push buttons. No manual controlled variable resistor / pots to be used in design. All digital control circuit.
Important part is power supply design & isolation
Submit your work schematic design via PM and best design will be awarded the PCB design.
Please quote how many hours you will take to design a PCB with your schematic.
