INTRODUCTION

Your credit cards: gone. Bus pass and train tickets: vanished.Welcome to Near Field Communications (NFC), a contactless, Wi-Fi-lite style tech that could already be in your smartphone, and could soon be a regular feature of your commute.
Near Field Communications(NFC) is a set of short-range wireless technologies, typically requiring a distance of 10cm or less, for two devices such as smartphones or the similar things very close to each other to establish communication. Communication is also possible between a NFC device and unpowered NFC chips such as tags, stickers, key fobs and cards which do not require batteries.
The NFC Module for Arduino is designed to extend this powerful feature for your project or application based on Arduino.It integrates a PN532 NFC controller from Philips.The driver interface for this product is UART interface of the microcontroller. So it’s possible for you to test it via a USB to UART converter directly. On the other hand, for the applications with microcontroller, the module provides an event for your processor when detects the NFC tags, stickers, key fobs, or cards via high speed serial uart.

Mini Thermal Receipt Printer

Add a mini printer to any microcontroller project with this very cute thermal printer. Thermal printers are also known as receipt printers, they're what you get when you go to the ATM or grocery store. Now you can embed a little printer of your own into an enclosure. This printer is ideal for interfacing with a microcontroller, you simply need a 3.3V-5V TTL serial output from your microcontroller to print text, barcodes, bitmap graphics, even a QR code!

This package comes with a thermal printer including the print head (it does not require ink, a set of power and data cables, and two plastic shims for panel mounting. Thermal paper not included! The printer uses very common 2.25" wide thermal paper, available in any office or stationery supply store. It can fit up to 50 ft of paper in the bay at once. You will also need a 5 to 9VDC regulated power supply, that can provide 1.5A or more during the high-current print - our 5V 2A power supply will work very nicely. We also suggest picking up a roll or two of 50' long thermal paper, and also a 2.1mm jack terminal block adapter which will make it easy to connect the power adapter. We also have a starter pack that includes all the above

We really like this printer because its easy to make Bold, underline, inverted text, variable line spacing, left/center/right justification, barcodes in 11 standard formats with adjustable height, and even custom bitmap graphics.

Of course, we wouldn't leave you with a datasheet and a "good luck!" - We have a full tutorial and matching CircuitPython and Arduino library that demonstrates the following:

  • Printing with small, medium and large text
  • Bold and underline text
  • Inverted text
  • Variable
    line
    spacing
  • Left, center and right justification
  • Barcodes in the following standard formats: UPC A, UPC E, EAN13, EAN8, CODE39, I25, CODABAR, CODE93, CODE128, CODE11 and MSI - with adjustable barcode height
  • Custom monochrome bitmap graphics!
  • How to include a QR code

Note: You will need a microcontroller that has a hardware or software Serial UART!
