3 Quick start
3.1 Getting started in standalone mode
The motherboard and the daughter board must be connected together.
The jumper configuration when the kit is de
livered is the default one.
The ST25R3916-DISCO kit is powered (like a
PC) by the micro USB bus via a cable
connected to the power source.
The unit must be supplied by a safety extra low voltage (SELV) limited power source
thro
ugh the USB port, the source must not exceed 60 V
DC
/ 8A / 100VA
When powered up, the microcontroller starts the firmware, which is already downloaded in
the F
lash memory.
This makes it possible to demonstrate the different cap
abilities of the ST25R3916.
• Reader and writer
• Car
d emulation
• Peer to peer
• Automatic antenna tuning
• USB mode (see Section 3.2)
There is no need for modifications or configurations
to run the demonstration. Refer to the
firmware’s user manual available on STMicroelectronics website to get more details.
3.2 Getting started with USB mode
Connect the discovery kit to a PC using a micro USB cable. The USB port of the PC must be
capable of delivering at least 250 mA at 5 Volt.
To control the board, download the software from the dedicated page on www
.st.com and
install it. Further information on how to operate the software and the GUI that can be used to
control the control the board can be found in UM2511 “ST25R3916-DISCO kit user manual”,
available on www.st.com.
3.3 System requirements
• Micro USB cable
• USB port, capable of delivering at least 250 mA at 5 V (1.25 W)
• Unit must be supplied by a safety extra low voltage (SELV) limited power source
through the USB port
• For embedded ST link and STM32 Nucleo ecosystem development usage a mini USB
cable is required
