Power Source Selection Connector (J8)
The jumper header J8, on the WINC1500 PICtail/PICtail Plus Daughter Board, is used
to select power source for the daughter board. The daughter board can be powered
either from the power supply of the base board or from the external USB supply.
Mounting the jumper in position 1-2 (pin 1 marked with overlay “BB” in the PCB) will
power the daughter board from the base board, and mounting the jumper in position
2-3 (pin 3 marked with overlay “USB” in the PCB) will power the daughter board from
the USB supply.
When the daughter board is powered from the external USB supply, it can still be inter-
faced to any base board with the PICtail/PICtail Plus connectors. The GND for the
PICtail daughter board and base board are common, and the both will operate at 3.3V.
A 5V input from the USB supply is provided to LDO (U3) to obtain the 3.3V for supplying
the daughter board.
2.1.7
Power Measurement Header (J6)
The jumper header J6, on the WINC1500 PICtail/PICtail Plus Daughter Board, can be
used to measure the current consumption of the ATWINC1510-MR210PB module. The
power to the ATWINC1510-MR210PB module is routed through this header.
To measure the current consumption of the module, connect a voltmeter directly across
the pins of J6. A 1
Ω
resistor is connected in parallel with the jumper header J6 which
provides 1:1 relationship between the voltage and current measured across the jumper.

PERIPHERALS
2.2.1
USB-to-UART Serial Converter (U2)
The WINC1500 PICtail/PICtail Plus Daughter Board has an on-board USB-to-UART
serial bridge/converter, which is used for observing UART debug logs from the
ATWINC1510- MR210PB module. The PC console can be connected to the daughter
board using a standard-A to micro-B or micro-AB cable.
The following UART configuration to be used in the PC console:
• Baud rate: 115200
• Data: 8 bit
• Parity: None
• Stop bit: 1
• Flow control: None

User LED
Two user LEDs are available on the WINC1500 PICtail/PICtail Plus Daughter Board
which can be turned ON and OFF. The LED can be activated by driving the connected
I/O line to GND.
