  • This is a prototype voltage source. It uses a 16-bit DAC to create voltages from 1 mV to 2.5 V and is controlled by an ESP32-S3 microcontroller. The UI consists of a small screen and 3 buttons and a rotary dial. The modules are interconnected with I2C using Qwiic jumpers.

    Really cool to see those Adafruit PCBs in use. I bought some but I have not had a plan to make use of them just yet. How useful would you rate it? Anything outstanding good or bad about it?

      Adafruit documentation on their learn site is very helpful. Adafruit also has a discord channel for support.

      @@N8FDYWhen you power on that unit,do i need to add on that USB cable an ferrite beard.

    Even as a (die-hard) Fluke-fan I was always interested in the Brymen 869s. But now I hear you start to dislike it more and more? Can you tell me what it is about this meter that makes you feel this way?

      Because of my vision problems I need the backlight to help read the screen. The backlight goes off after 4 minuets and 16 seconds. There is no way to override this behavior. To turn it back on you have to press the select button for 1 second or more, and if you do it less then 1 second it changes the function for that rotary switch setting. The meter also remembers the select mode even after power off and back on. Sometimes I don't press the select long enough and in change form DC to DC+AC,, and that changes the readings a bit. I once shot a whole set of pictures with voltage measurements before I noticed it was in DC+AC so I had to redo it. I know this is a little nit but it still annoys me. I am sure a normal sighted person would not need the backlight on all the time and everything else about this meter seem pretty good.

      Thanks for the elaborate answer. I agree that holding a button for a longer time to use the backlight which otherwise has another function is not always that practical, for instance I have an Owon clamp meter that has one button for HOLD and (long press) Backlight and I too find it not really convenient at times. I prefer to have dedicated backlight buttons.
