XBee 6.3mW Wire Antenna - Series 2C ZigBee Mesh

Cable USB to Serial Adapter RS232, 1,5m Length.

USB2.0 Standard, Backward Compatible, According to RS485 Standard.

Converter SSOP28 to DIP28.

This is the newest revision of the FTDI Basic. There is a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same.

This is a basic breakout board for the FTDI FT232RL USB to serial IC. 

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.

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.

An RFID Reader with PIN Code , from Orno.

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.

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.

RF Link Transmissor - 434MHz

Programador AVRISP STK500 AVR USB Atmega Attiny

Módulo 433MHZ LORA com alcance 3000m.

The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.

This is a simple three track magnetic card reader with serial output.
