Overview
  • This simple and cheap device has many uses, but it’s mainly intended to replace multiple panel meters.
  • It can also be used as a small additional text screen for PC, Raspberry Pi or any other computer with USB.
  • Whilst working on the high-current linear power supply design it became clear that we needed a way to show several different voltage and current readings, along with heatsink temperature, and it just didn’t make sense to use several panel meters for that job.
  • It’s difficult enough to cut a single neat rectangle in the front panel of the instrument case to fit one screen, let alone three or even five.
  • And there would be a lot of extra wiring if we used separate panel meters, plus increased current draw and it could end up pretty expensive.
  • This one low-cost device using a micro, an LCD screen and not much else makes the whole thing so much easier.
  • There are two ways to use this board. In the Bench Supply, we’re feeding in five analog voltages with a common ground. These voltages are a fraction of the actual measured voltages (ie, the outputs of voltage dividers).
  • The onboard micro samples these voltages and converts the values back to the original scales, then displays on them on the screen.
  • In the case of the fifth input, which is used for temperature sensing via an NTC thermistor, it also performs the required calculations to deal with the non-linear behaviour of the NTC.
  • In the other mode, the micro detects when it is plugged into a USB interface and then behaves differently.
  • You send it text over a virtual serial link, which is shown on the display.
  • So you can easily show whatever you want on the 16x2 or larger 20x4 character backlit LCD screen.

Important Note For Kit Buyers:

  • This product is supplied in component form and requires soldering, drilling, and assembly.
  • We recommend users are familiar with at least basic electronic principles and have the ability to solder.
Features
