3 Jumpers

This chapter describes all jumpers that can be modified on the probe. The default setting is
shown with a grey shaded area. All jumpers are named directly on the board, so it is very
easy to set the jumpers according to the features.

3.1 Power Supply Voltage (JP: 99, 100, 101, 102, 103)

3V3 and 5V are the supply voltages for the Level shifters. The Jumpers JP99 and JP101 in
conjunction with S1 and S2, allow to use an externally power supply for the Level shifters. In
that case, take care of the input-voltage. Neither a voltage regulation nor an over-voltage-
protection does exist for an external power-supply. The default setting is supplying the level
shifters with UVCC3 and UVCC5 directly.
