Getting started with the STEVAL-ST25R300KA kit based on the ST25R300 highperformance NFC universal device and EMVCo reader
Introduction
The STEVAL-25R300KA is a ready-to-use kit based on the ST25R300 high-performance NFC universal device for contactless applications. The kit allows evaluating this device features and functionality in the reader/writer, and card emulation modes. The kit consists of: · a microprocessor main board (STEVAL-M25B1), which includes hardware and software tools that enable using the entire
STM32 ecosystem. This board is powered through USB connectors · a reader expansion board (STEVAL-D25R300A), which embeds the ST25R300 device and an antenna etched on the
PCB with its tuning circuit The communication link between the two boards is the SPI bus. The processor card provides the power. Specific data lines complete the pin connector assignment shared between the cards. Thanks to several demonstrations that can be performed, this kit helps the users develop and test their applications. The kit is FCC certified, with FCC ID: YCPR300AD1. It is also IC certified, with IC: 8976A-R300AD1; PMN: STEVAL-25R300KA; HVIN: STEVAL-25R300KA.

Hardware overview
The main board PCB is usually connected to the PC via USB. The STM32 MCU firmware controls the ST25R300 via the extension connectors. The 5 V supply of the USB bus powers both boards. An LDO converts this voltage down to 3.3 V to supply the microcontroller and the ST25R300. For the reader expansion board, you can select a 3.3 or 5 V RF powering. A green LED close to the motherboard micro-USB C plug indicates when the board is powered.

Expansion board hardware
The STEVAL-25R300KA reader expansion board embeds:
·
ST25R300
·
an antenna, with its own tuning circuit, etched on the PCB
·
a switch to select 3.3 V or 5 V RF powering
The ST25R300 is directly connected to the filtered 5 V USB supply.
There are additional supply filtering components close to the NFC/HF reader IC. All the decoupling capacitors have been placed as close as possible to the ST25R300.

System requirements
·
A USB C port capable of delivering at least 500 mA at 5 V (2 W)
·
A safety extra-low voltage (SELV) limited power source to supply the unit through the USB port
·
A mini-USB cable to use the embedded ST-LINK and the STM32 ecosystem development
3.2
How to use the kit in standalone mode
Step 1. Connect the STEVAL-25R300KA main board to the reader expansion board.
Important: It must be used on a clean and non-flammable surface.
Step 2. The kit is delivered with the default jumper configuration. Power it through the mini-USB via a cable connected to the power source.
Step 3.
Supply the unit through a safety extra-low voltage (SELV) limited power source via the USB port. The source must not exceed 60 VDC/8 A/100 V. When powered up, the microcontroller starts the firmware, which is already downloaded in the flash memory. This allows demonstrating the ST25R300 features:
reader and writer card emulation automatic antenna tuning USB mode (refer to the next section for further details)
3.3
How to use the kit in USB mode
Step 1. Connect the STEVAL-25R300KA kit to a PC via a mini-USB cable.
Important: It must be used on a clean and non-flammable surface.
The PC USB port must be capable of delivering at least 250 mA at 5 V.
Step 2. To control the board, download the STSW-ST25R022 software and install it.

Regulatory compliance information
Notice for US Federal Communication Commission (FCC)
Part 15.19 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Part 15.21 Any changes or modifications to this equipment not expressly approved by STMicroelectronics may cause harmful interference and void the user’s authority to operate this equipment. Part 15.105 This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: – Reorient or relocate the receiving antenna. – Increase the separation between the equipment and receiver. – Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. – Consult the dealer or an experienced radio/TV technician for help. FCC ID: YCPR300AD1
Notice for Innovation, Science and Economic Development Canada (ISED)
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence exempt RSS(s). Operation is subject to the following two conditions: (1) This device may not cause interference. (2) This device must accept any interference, including interference that may cause undesired operation of the device. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. [only if EMC testing performed on the radio board as well:] This class B device complies with Canadian Interference-Causing Equipment Standard ICES-003: CAN ICES-003(B) / NMB-003(B) Conformité à Innovation, Sciences et Développement Économique Canada (ISDE) L’emetteur/recepteur exempt de licence contenu dans le present appareil est conforme aux CNR d’Innovation, Sciences et Developpement economique Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisee aux deux conditions suivantes: (1) L’appareil ne doit pas produire de brouillage; (2) L’appareil doit accepter tout brouillage radioelectrique subi, meme si le brouillage est susceptible d’en compromettre le fonctionnement. Les changements ou modifications non expressément approuvés par la partie responsable de la conformité pourraient annuler l’autorité de l’utilisateur à faire fonctionner l’équipement. [only if EMC testing performed on the radio board as well:] Cet appareil numerique de classe B est conforme à la Norme sur le Matériel Brouilleur NMB-003 du Canada: CAN ICES-003(B) / NMB-003(B) IC: 8976A-R300AD1; PMN: STEVAL-25R300KA ; HVIN: STEVAL-25R300KA
