    I would like to get a PCB designed to interface a caliper with arduino. Basically the idea is to have a PCB where is possible to solder a sparkfun ardiuno promini and some additional components (transistors, resistors). All the system will be installed inside a plastic box and micro USB should be accessible from outside. Check attached scheme.

    I used the below circuit to generate high current analog output (0-10V) from PWM input by changing the duty cycle of the PWM. It works well when I use 5V PWM that comes from Atmega8 microcontroller. See Drawing One However, using the same circuit with 3.3V PWM that comes from ESP8266, it does NOT work. It gives only 2V output. See Drawing Two Could you please make similar board in your bench...

    I have a tested PCB design, I simply need the design to be more space efficient. It drops the DC voltage from a battery network down to a lower voltage and uses an external 12VDC signal to trigger a relay to fire the shunt coil on an MCCB using the battery voltage as it's supply. The OHM and wattage of the resistors mounted externally can be selected to allow the PCB to work with different ...
