Building SWR bridges is pretty easy for most people here and there are many examples on the internet to follow if you want one.? The difficulty with the uBITx in its current form is finding a way to bring the Vfor and Vref signals into the Radurino for calculation and display.? You either have to do some pin juggling… or move some current analog features to the I2C buss.? That’s where the challenge is.
