Vin rail: This is where the input of the on-board regulators are connected. This domain is
powered through protection diodes.
5-V rail: This is the output of the 5-V regulator U2. The rail is a fixed 5 V output regardless of
jumper settings. The voltage in this rail can be less than 5 V only when the board is powered by
the USB. This 5-V rail powers the circuits that require fixed 5 V supply.
3.3-V rail: This is the output of the 3.3-V regulator U4. This rail remains 3.3 V regardless of
jumper settings or power source changes. It powers the circuits requiring fixed 3.3 V supply such
as the on-board programming section.
Vddd rail: This rail provides power to the digital supply for the PSoC device. It can be derived
from either the 5 V or 3.3 V rail. The selection is made using J10 (3-pin jumper).
Vdda rail: This rail provides power to the analog supply of the PSoC device. It is the output of a
low noise regulator U1. The regulator is a variable output voltage and can be either 3.3 V or 5 V.
This is done by changing the position on J11 (3-pin jumper).
