 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.
 Voting Box’s core part
 Voting Box’s interface
USB: Just for battery’s charging. No use communication function.
Switch: Power ON/OFF Voting Box
DFU Switch: Upload Nrf51822’s firmware
Buzzer:Buzzer will on when completed NRF read
Battery connector: Connect a button cell, keep Voting Box’s RTC working all the time.

Power on Voting Box by turn the switch to on terminal.
Make sure buzzer and LEDS on Voting Box will on/off several times.
Place the NFC tag near to the NFC antenna.
Make sure the buzzer and LEDs will on/off when NFC tag near Voting Box.
Administrator can access the NFC tag information from the server.
Warning
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Warning: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to
radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the
receiver is needed.

Consult the dealer or an experienced radio/TV technician for help.
The device has been evaluated to meet general RF exposure requirement.
The device can be used in portable exposure condition without restriction
