 Voting Box
Voting Box integrated with Bluetooth low energy and NFC.it use NordicnRF51822 and
NXP PN532 to achieve the Bluetooth and NFC function.
 Voting Box’s Bluetooth Low Energy
The nRF51822 is a powerful, highly flexible multiprotocol SoC ideally suited
for Bluetooth® low energy and 2.4GHz ultra low-power wireless applications.
The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB/128kB flash +
32kB/16kB RAM for improved application performance. The embedded 2.4GHz
transceiver supports both Bluetooth low energy and the Nordic Gazell 2.4 GHz protocol
stack which is on air compatible with the nRF24L series products from Nordic
Semiconductor.
nRF51822 incorporates a rich selection of analog and digital peripherals that can interact
without CPU intervention through the Programmable Peripheral Interconnect (PPI) system.
A flexible 31-pin GPIO mapping scheme allows I/O like serial interfaces, PWM and
quadrature demodulator to be mapped to any device pin as dictated by PCB requirements.
This enables complete design flexibility associated with pin-out location and function.
nRF51822 supports Bluetooth low energy protocol stacks as well as 2.4GHz protocol
stacks, including Gazell, both available as downloads. nRF51822 requires a single power
supply and gives the user the option of using on chip linear regulators giving a supply
range of 1.8-3.6V, a direct 1.8V mode and a on chip DC-DC buck converter giving a
supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled
during run time and enables nRF51822 to operate at radio peak currents below 10 mA @
3V supply (TX @ 0 dBm& RX).
 Voting Box’s NFC
PN532 is a highly integrated transceiver module for contactless communication at 13.56
MHz based on the 80C51 microcontroller core supporting different card and reader/writer
operating modes
 Voting Box’s function
Voting Box can scan the NFC Tag and save the information to the server by the mesh net
created by Bluetooth Low Energy.
