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 a fantastic find for SFE. A small, high-quality, quad-band, standard SMA terminated, cellular antenna.

3dBi GPS antenna SMA connector

Need range? The 2.4GHz Large Duck Antenna 5dBi with Reverse Polarized - SMA RF connector is perfect for you.

The RFID USB Reader is a simple to use, USB to serial base unit for the ID-3LA, ID-12LA, and ID-20LA readers. 

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.

It is an easy to use Sensor ID 125Khz Card Reader. Quick to read RFID tags. Plug and play, no extra driver needed. Used in many RFID application systems, such as personnel identification, logistics, access control, conference system, anti-counterfeiting system and industrial production process control.

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.

With this GSM Module, you can control devices by sending SMS messages. It is controlled via AT commands and can be integrated with your Arduino projects. Designed for the global market, modules based on the SIM900A feature the GSM/GPRS bands of EGSM 900MHZ and DCs 1800MHz.
