PCB a Week 2: DigiPot

DigiPot-pcb

Matseng continues his challenge of designing one PCB a week. The latest PCB is DigiPot, a digital potentiometer with a rotatory encoder for control, and a 4 digit 7-segment used to display the current value.

The basic idea is a digital potentiometer with a 7-segment display that shows the current value. The “potentiometer” is a Rotary Encoder connected to a microcontroller [TBD] that will read the signals from it and convert it to a value that is displayed on the 7-segment displays.

Via the forum.

    I bet it’s the size of a dime.

    Matseng makes some cool stuff!
    When is he going to start selling these things through Seeed?

    I see the rotary encoder has a central push button. It would appear this project has every thing needed for a compact minimalist PID controller , it is much more capable than a simple digi-pot display and you should advertise that. Very nice.

  • KH: Really? They are digital inputs driven by an MCU. The MCU GPIO probably has diode clamps and ESD protection. Have you experienced such failures? Please...
  • KH: Neither. Google "Marco Schweighauser’s 8-bit virtual Javascript CPU" and see the first result. Sounds more like a very limited feature toy CPU.
  • Alan: "8-bit x86 like CPU" - isn't that an 8080, or Z80?
