The ST25R3916-DISCO kit allows the user to evaluate the features and capabilities of the
ST25R devices, a series of high performance HF readers.
The kit comes with application notes, soft
ware applications, drivers, BOM (bill of materials),
board schematics, Gerber files and firmware schematics. All these documents can be
downloaded from www.st.com, they help the user to reduce the design efforts.
The kit is composed of two boards:
1. The MB1396 (ST25_Discovery_Mboard) is a micropr
ocessor motherboard embedding
a 32-bit microcontroller of the STM32L476 line, based on Arm
®(a)
Cortex
®
-M4
high-performance CPU with FPU.
The MB1396 is powered through the USB bus. It includes:
– an ST-LINK in-circuit debugger and programmer for STM32 microcontrollers
– a 2.4”
TFT LCD with touch screen capability
–LEDs
– push buttons (reset and user)
– a mini USB debug connector
– a user-dedicated micro USB connector.
– features for ST NFC TAG
2. The MB1414 (ST25R3916_Discovery_DB) daughter
board, which embeds the
ST25R3916, an antenna etched on the PCB and its tuning circuit. A switch allows the
user to select 3.3 V or 5 V RF powering.
