JOY-iT Joy-Pi Note - 11.6” Raspberry Pi 4-based Notebook
3-in-1 Solution: Notebook, Learning Platform and Experiment Center The Joy-Pi Note is the new flagship in the Joy-Pi family. With its 11.6" IPS screen and a detachable, wireless keyboard, it takes the Joy-Pi‘s basic concept in a new, high-quality and attractive format. With 46 courses and 18 projects, the Joy-Pi Note is not only suitable as an experiment center, but is also ideal for use in the education sector. With over 22 integrated sensors and modules, there are no limits to the user‘s own joy of experimentation. This simplifies the introduction to electrical engineering and programming. Due to the installed learning platform, which was developed especially for the Joy-Pi Note, the installed units can be operated and learned independently of one‘s own previous knowledge. It is also possible to connect additional sensors and modules via the pins of the Raspberry Pi, which are routed to the outside, and thus also carry out more complex projects. Of course, the Joy-Pi Note can also be used as a „classic“ notebook. All programs compatible with the Raspberry Pi 4 can be installed. The integrated 2 MP camera also makes video conferencing possible, for example. All Raspberry Pi 4 models can be used (we recommend 4 GB RAM or higher). On the bottom of the device, you will find a compartment where you can insert a power bank to also operate the Joy-Pi Note mobile. Specifications Main Features Screen 11.6" 1920x1080 IPS LCD Camera 2 MP Special features Fully equipped set, completely integrated experiment center, pre-installed learning platform, detachable wireless keyboard, integrated compartment for powerbank & accessories Lessons of the learning platform 46 courses & 18 projects for Python and Scratch Power supply 12 V hollow plug, 5 V USB Compatible to Raspberry Pi 4 (4 GB and 8 GB RAM) Keyboard layouts DE (default) + US, UK, FR, IT, PT and Nordic Dimensions 291 x 190 x 46 mm Weight 1.3 kg Included sensors, modules & accessories Display 7-segment display, 16x2 LCD module, 8x8 RGB Matrix Sensors DHT11 temperature & humidity sensor, tilt sensor, motion sensor, sound sensor, touch sensor, RFID module, light sensor, ultrasonic distance sensor Motors Servo interface, stepper motor interface, vibration motor Control Joystick, 4x4 button matrix, Raspberry Pi & PCB connection switch, motion sensor, sensitivity controller, sound sensor sensitivity controller, 16x2 LCD module brightness controller Others Relay, fan, GPIO extension, GPIO LED indicator, breadboard, IO/ADC/I²C/UART expansion interface, infrared sensor interface, buzzer, display driver Accessories RFID chip, RFID card, 12 V power supply, servo motor, stepper motor, infrared receiver, infrared remote control, DC motor with fan attachment, HDMI connector, screwdriver, microSD card (32 GB), SD card reader, electronic accessories, wireless mouse, wireless keyboard Included Joy-Pi Note Accessories Quick guide Required Raspberry Pi 4 (4 GB or 8 GB RAM)

Makerfabs Makerfabs PN532 NFC Module V3
NFC is a popular technology in recent years. Almost all the high-end phones in the market support NFC. Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. This module is built around NXP PN532. NXP PN532 is very popular in the NFC area. Makerfabs developed this module based on the official document. A library for this module is available. Features Small dimension and easy to embed into your project Support I²C, SPI, and HSU (High-Speed UART), easy to change between those modes Support RFID reading and writing, P2P communication with peers, NFC with Android phone Up to 5~7 cm reading distance On-board level shifter, Standard 5 V TTL for I²C and UART, 3.3 V TTL SPI Arduino compatible, plugin and play with our shield RFID reader/writer supports Mifare 1k, 4k, Ultralight, and DESFire cards ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX) Innovision Jewel cards such as IRT5001 cards FeliCa cards such as RCS_860 and RCS_854 Downloads Usage NFC Library

IoTize IoTize TapNLink Primer NFC-BLE-WiFi Evaluation Kit
With TapNLink Primer, it takes just minutes for system designers to create their first IoT proofs-of-concept. The Primer connects microcontroller-based systems to mobile devices via Wi-Fi, Bluetooth Low Energy (BLE) or Near Field Communication (NFC) interface. Users can rapidly and easily create Human-Machine Interfaces (HMI) that run as mobile apps for any microcontroller-based system. The Primer connects to a target MCU using only 2 GPIO and either: Serial protocol (S3P – Sofware Secure Serial Protocol) SWD (debug) protocol for ARM Cortex M-based microcontrollers The Primer implements by configuration only. There is no coding or hardware to design. Just specify the variables in the target system, set access rights and display parameters. The Primer's configuration software, IoTize Studio, automatically generates the HMI for your mobiles (Android, iOS). In just minutes, you will be able to connect a mobile to your microcontroller application, and view, or change data from your mobile app. Physical Characteristics PCB dimensions: 38 mm x 28 mm x 3 mm Security Features Configurable access profiles Configurable, encrypted passwords Configurable BLE pairing using NFC Mobile Platform Support HTML5 web apps Cordova-based hybrid apps (native, Java) Automatic app generation (Android, iOS) Included 1x TapNLink wireless module (Wi-Fi, BLE, NFC interfaces) 1x ABS plastic cover 1x Six-probe connection cable 1x STM32 sample application board and software FREE Supporting Software IoTize Studio configuration software for Windows PCs Tap Manager app for mobile devices (Android, iOS) Arduino Tap library for Arduino integration (on GitHub) MQTT relay (open source) The TapNLink Primer also includes sample microcontroller application firmware for all STM32 microcontrollers and an accompanying Sensor Demo app for Android and iOS mobiles to help you get started.
