Beware - these need to be updated with actual assembled board. v2 includes sees top going bottom and vice versa.

Signal coming out of a cheap DSO, should be around square, 4MHz

Remove i2c to something simpler - MCP40D17T Let user choose offset or not Check OPAMP capa to get a 60MHz cutoff BAV / MD0100 to be removed * Putting the rp2040 under the board, to expose the beautiful art to users
