This is the very popular 2.4GHz XBee module from Digi (formally Maxstream). These modules take the 802.15.4 stack (the basis for Zigbee) and wrap it into a simple to use serial command set. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
Pair a couple of these XBees with a Regulated Explorer, and a USB Explorer and you’ve got a great gift for that special electronics geek!
With Ethernet relay, IoT has become so easy. RLY-8-POE-USB is a POE & USB controlled 8 channel relay controller based on STM32. With this module users are able to do remote control/ switching power supply centralized management, the purpose of this product can be directly by net POE power supply switch power supply is connected to the Internet, so you just need to a cable link equipment, suitable for: home decoration, hotel, shopping mall management, Internet cafes, karaoke time, daily office, stores monitoring, networking, industrial control equipment, test equipment, power control, unattended, underground pipes, mining equipment, ships, machine room, street lamp management, intelligent management and centralized management.
Please read the PoE compatiblity issue before you buy:
We have passed the test on PoE Switches, list as
HC-06 is a Bluetooth module designed for establishing short range wireless data communication between two microcontrollers or systems. The module works on Bluetooth 2.0 communication protocol and it can only act as a slave device. This is cheapest method for wireless data transmission and more flexible compared to other methods.
CC2530 Eval Kit is a ZigBee development/evaluation kit designed for CC2530F256, consists of the mother board ZB502 and the ZigBee moduleCore2530.
Basically this kit can be used in two aspects :
Develop application with the provided firmware
Combined with our provided firmware, you can use this kit to set up a minimal ready-to-run ZigBee system for testing or evaluating, and requires NO knowledge about the complicate ZigBee Specification
Develop your own firmware
In this case, you should start from the very underlying to create your solution, what’s more, debuggers (like CC Debugger) and knowledge about ZigBee Specification are also required
This is RFID 13.56MHz Card used for Contactless transmission of data and supplies energy with no battery needed. Its Operating distance is Up to 1 Meter depending on antenna geometry. Operating frequency is 13.56MHz and Data transfer speed is 106 kbit/s. It is featured with Data integrity of 16 Bit CRC, parity, bit coding bit counting which allows Anti collision. These cards are typically used in ticketing transaction: <100 ms including backup management.

This is the XBee XB24-Z7CIT-004 module from Digi. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU.
This Xbee also has a chip antenna which is basically a small chip that acts as an antenna. Quick, easy, cheap, and not in the way.
This is the very popular 2.4GHz XBee XBP24-ACI-001 module from Digi. The Pro series have the same pinout and command set of the basic series with an increase output power of 60mW! These modules take the 802.15.4 and wrap it into a simple to use serial command set. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
