2.2.2
STLink board The STLink is the in-circuit debugger and programmer for the STM32G0 microcontroller located on the ST25R200 module application board. The serial wire debugging (SWD) is the bus interface for this communication. It also provides a Virtual COM port interface allowing the host PC to communicate with the target microcontroller through a UART. STM32 applications use the USB full-speed interface to communicate with the STM32CubeIDE software tool or ST25R200 GUI running on the host PC. The 5 V supply of the USB bus powers the boards. An LDO converts this voltage down to 3.3 V to supply the microcontroller and the ST25R200. A green LED indicates when the board is powered. The board is breakable and can be used independently. On the back side, the PCB pad signal names are indicated for wire connections or for a solderable system module.

ST25R200 module
Presentation The ST25R200 module embeds the ST25R200 reader device and a STM32G0B1KEUxN processor. The 5 V supply of a USB bus powers the boards. Usually, the board is powered by the STLink board. If the ST25R200 module is used separately, other possibilities are offered (Table 2). An LDO converts the voltage applied down to 3.3 V to supply the microcontroller and the ST25R200. A connector allows to plug an antenna. Five antennas are delivered with kit, the main NFC Antenna of 20×25 mm size etched on the PCB with its tuning circuit is delivered connected to the ST25R200 module (Table 1). This board is breakable and can be used independently. On the back side the PCB pads signals names are indicated for wires connections or for a solderable system module (Figure 2). Thanks to the STM32G0 IOs modularity the pins can be used for different configurations; a pre-assignment is proposed with associated IP functions, but alternate functions can be chosen too (Table 3). Three bi-color LEDs are available for indicating events, by default they are assigned to the demo by the firmware. Two footprints are provided for using the board in standalone mode, a USB and an STLink.

Antenna tuning
Tuning compatible with all the antennas delivered imposes a tradeoff due to the presence of the EMC filter on the main board. Optimum matching is not delivered for each antenna and manual fine tuning is required. Dedicated tools and tuning application notes are available on ST web site. The antenna impedance must be calculated to remain below 250mA. Normally, it should be the case for 18-20 ohm tuning.
NFC tags
The tag boards are available for reader&tag system evaluation. The antennas delivered are very small, which can impact the reader plus tag system if the application requires a long range. In this case, please refer to the design recommendations provided on the ST website NFC.
Tag 1: ST25TV This board embeds a ST25TV (ST25TV02K-CAFH3 UFDFPN5) with its tuned 10 x 5mm antenna. Two PCB pads are available for temper detect evaluation TD0 & TD1. To use them, the solder bridge SB1 must be removed.
