O GP-735 é um receptor de antena inteligente GPS simplista, de alto desempenho e fácil de usar. Com sensibilidade de rastreamento de -162dBm e apenas 29 segundos de tempo de início após uma longa paragem, o GP735 é uma peça de tecnologia minúscula, porém poderosa. O design fino torna ideal para aplicações onde você não tem muito espaço para trabalhar.

O SM5100B é um módulo GSM miniatura, quad-band 850 / EGSM 900 / DCS 1800 / PCS 1900, que pode ser integrado num grande número de projetos sem fios. Você pode usar este módulo para realizar quase qualquer coisa que um telemóvel normal pode - mensagens de texto SMS, GSM / GPRS, o TCP / IP, e muito mais!

O complemento Raspberry PI GSM V1.0 é personalizado para a interface Raspberry Pi baseada no módulo SIM900 quad-band GSM / GPRS.

2.4 GHz 3dBi foldable antenna with reverse bias - SMA RF connector. Perfect for prototyping with RF ICs and Xbee modules. 50 ohm impedance. 10.16cm in length.

This is the ID-20LA , very simple to use the RFID Innovations ID reader module. With a built-in antenna , the only protrusion is the 2mm pin spacer . Just power the module, use a 125kHz card , and get a serial chain output that contains the card's unique identification.

This is an os card for our RFID readers . The SparkFun L eid RFID Breakout converts the 2mm pins to the breadboard in a friendly 0.1 "headers. With this ability the ID-3LA, ID-12LA, and ID-20LA you can weld the reader directly to the header or use the 2 mm connectors

The RFID Smart Lock can provide good security protection for your personal items, in addition to protecting your privacy. It can also improve the safety of children at home, prevent them from being free to open drawers or cabinet doors.

Each Card pre-programmed with a unique identification number, printed on the card. The Identification Card is suitable for the 125KHZ Card Reader and the Reading Distance is 0cm to 10cm. Used in Identification, Financial Identification, Access Control Systems, Low Frequency Identification Cards and so on. Read-only, not HID card.

At ElectroFun we have a few different GPS modules, but none that met all of our wishes - that's why we acquired this small GPS card. This is the Ultimate GPS Module.

This module integrates a Zhongke Weibeidou AT6558 navigation chip and a MAX2659 amplification chip used to amplify the antenna signal. The AT6558 has high performance, supports many types of satellite navigation system, capable of receiving satellite signals on 56 GNSS signal channels from 6 satellite navigation systems, joint location, navigation, weather and more. The module is able to obtain accurate information of global location, fast and precise positioning for any place.

The module can be widely used in vehicle monitoring, car navigation, on-board navigation, notebook navigation, etc. You can connect it to Port C on the M5core via the Grove cable, which is a standard UART interface.

This is a wireless communication module, integrated with the M8321 NB-IoT module, which provides TD-LTE / FDD-LTE / WCDMA / TD-SCDMA / GSM / GPRS / EDGE frequency band and LCC + LGA package type. It integrated abundant Internet protocols, standard field interface and functions, supported WindowsXP, Windows7, Windows8, Windows10, Linux and Android USB driver.

In the layout of the LTE-4G module, more hardware resources were added, reserved lanes for speakers, 3 LEDs, USB interface, double antenna allowed.

The MFRC522 operates in the frequency range of 13.56 MHz and uses the principle of modulation and demodulation to interact with the RF proximity card. This unit can perform the function of the card reading and writing device, to identify and record various information on the card, to encode and authorize an RF card.

The Car Ring: Bit is a small smart DIY car driven by the Micro: Bit of the BBC and Ring: Bit. The Ring: Bit extends the 3 GPIO ports of the Micro: Bit and allows different sensors and components to be easily connected to the Micro: Bit.
