Change ADC full-scale range?

Hi to all users, I'm a newbie about redpitaya.
Taking a look to schematics I find 2Vpp and 40Vpp hardware selectable range.
For 2Vpp range I can see 499k+499k resistive partitor while for 40Vpp I can see 10M+200k resistors.
How can I change values for custom full-scale voltage?
Thanks.

Hi and thank you for your post.

We do not recommend that you modify the board and lose the warranty, and if you need a bigger input voltage range, just use an additional external attenuator before our board. We also recommend that you run the calibration after that.
