5.2 Jumpers of the evaluation board SK-91460-MAIN V1.2
In this section only the jumpers, influencing the adapter board are explained. Please refer to
the user guide of the evaluation board SK-91460-MAIN V1.2 for the other jumpers and
switches.
5.2.1 Analogue Power Supply Voltage
The power supply for the ports of the adapter board is generated by the evaluation board.
The voltage is selectable between 3.6 V and 5 V.
Jumper Setting Description
closed The microcontroller interface is powered with 3,3V
SL260
open The microcontroller interface is powered with 5V
closed Power supply MCU_Vcc is connected
SL262
open Power supply MCU_Vcc is disconnected
closed 3,3V is supplied to UVCC3
ST370
open 3,3V is not supplied to UVCC3
closed 3,3V is supplied to VCC3C
ST371
open 3,3V is not supplied to VCC3C
Default: SL260 = open SL262 = closed
ST370 = closed ST371 = closed
By default, the I/O-ports are supplied by 5 V.
Note:
1) The Jumper S28 of the adapter board selects UVCC3 or MCU_VCC (UVCC5) as
power supply for the I/O-port. By default this Jumper selects MCU_VCC (UVCC5).
