WaveShare NFC/MIFARE Development Kit ST25R3911B

Product detailed description

The kit integrates all the necessary components to develop your own NFC application. It is an NFC chip ST25R3911B, 1.3" OLED display with SH1106 driver, microSD card reader, 4 buttons, 2 programmable LEDs and as the main microcontroller is used ARM microcontroller STM32F103R. The power supply of the kit is provided by a microUSB connector, which also serves to transfer data to/from the microcontroller. The UART-USB converter used is type CP2102GMR. Other unused pins of the microcontroller are brought out on the board for custom expansion. There is a SWD connector on the board as a programming interface.

The whole kit comes assembled in a plexiglass box. The kit comes with a USB microSD card reader, a 16GB microSD card and a microUSB cable for connection to a PC.

There is a demo code that is already loaded in the microcontroller from the manufacturer. It is written using HAL libraries from ST microelectronic, so the original STM32 Cube configuration software can be used for development and Keil uVision is used as a compilation program. However, you can also use the original STM32 Cube IDE compilation software or other compilers supporting STM32 HAL libraries.

The demo code allows you to update the content of the NFC ePaper modules.

All details including schematics and source code for the demo software can be found in the Resources section at the link below.
