Has anyone any experience with the oscilloscope 'hat' for the RPi, made by Velleman (their VM205). It fits happily, and the software is working, but the instructions are a bit minimal.
In particular, there is a potentiometer on the board but no indication of its purpose. There is also a small connector beside the large set of pins for input/output, but no information about what it is for either.
Anyone know, please?
Philip.

Quick google search brings up
Page 7 for connector pins
As to the Potentiometer it is probably for calibration so do not touch unless you have a means of calibrating the device.

Thanks, Paul. Waning re pot noted.
One gets a printed version of the manual with the board, and the pin connections are given in that. But the connector I'm asking about is next door to the pins, on the edge of the board and roughly halfway along its length. It is a socket rather than pins, and appears to have
5 connections.Philip.

could it be an in-circuit programming connector for whichever micro controller is on the board?
-- In his book, Mr. DePree tells the story of how designer George Nelson urged that the company also take on Charles Eames in the late 1940s. Max's father, J. DePree, co-founder of the company with herman Miller in 1923, asked Mr. Nelson if he really wanted to share the limited opportunities of a then- small company with another designer. "George's response was something like this: 'Charles Eames is an unusual talent. He is very different from me. The company needs us both. I want very much to have Charles Eames share in whatever potential there is.'" -- Max DePree, chairman and CEO of Herman Miller Inc., "Herman Miller's Secrets of Corporate Creativity", The Wall Street Journal, May 3, 1988
