ZEBRA CONFIDENTIAL: INTERNAL USE ONLY ZEBRA TECHNOLOGIES 3
1 – Getting started
Connect EMA NFC READER BOARD to an STM32 via an SPI differential to SPI converter
(LTC6820IUD). The supply voltage has to be capable of delivering at least 300 mA at 5 V supply. A
demo software is available for download at www.st.com to be programmed onto an STM32.
To use the STM32 Nucleo boards with the EMA NFC READER BOARD the
following software and hardware are required:
• an STM32 Nucleo-64 development board
• a Windows® PC to install the firmware package
• interface board using LTC6820IUD
• a USB type A to Mini-B USB cable to connect the Nucleo board to the PC
• unit must be supplied by a safety extra low voltage (SELV) limited power source through the
USB port, the source should not exceed 60Vdc / 8A / 100VA
To install the board firmware package (order code: X-CUBE-NFC5) the PC must have:
• 128 MB of RAM
• 40 MB of free hard disk space
EMA NFC READER BOARD can be loaded with firmware and has ST25R3911B related
documentation both available at www.st.com.
2 – Board setup
To set up the board:
1 - Connect the EMA NFC READER BOARD to the STM32 board via SPI differential to SPI
converter (STM32 and SPI converter could be part of the same PCB design)
2 - Power the STM32 board using 5V power supply
3 - Program the firmware on the STM32*
4 - Reset the MCU and the NFC Reader board is ready to be used.
*All required documentation for STM32 programming could be found on www.st.com
