The proxmark3 is a powerful Penetration Testing and Research and development RFID tool. It is designed to snoop, listen and emulate everything from Low Frequency (125kHz) to High Frequency (13.56MHz) tags. It can act as a reader, a writer and clone a RFID tag. It can eavesdrop on a transaction between another reader and a tag, analyze a signal to perform...
This module let you control four 250VAC - 10A relays with a 5V signal (15-20mA). Just send a logic TTL Active LOW signal from a microcontroller (Arduino, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, MSP430) to switch the relay on. Inputs are Opto-isolated and there's Indication LED’s for Relay output status.
Don’t limit your projects, think big, think MEGA! Genuino Mega 2560 has been designed with bigger and more ambitious projects in mind. The large number of analog and digital pins, together with a larger memory makes it ideal for devices like 3D printers and other demanding applications.
This Lipo battery charger board allows to charge and power your project with a stable 5V voltage from a Lithium batterie, a solar panel and/or from USB. No programming is required. Plug it in and it works. The internal charger IC handles all the power flow between the various components.
OLED displays are nice to print characters, bitmap images or different shapes like circles and rectangles. They also have a minimal power consumption and are suitable for battery powered applications. This Oled screen uses the SSD1306 chip and is driven with 2 wires I2C. It is compatible with the most of Arduino libraries.
If you are curious to check how much current your device draw, this USB current/voltage meter is really handy. Just plug a USB cable from the power source to the IN port and the cable of your device into the OUT port. Voltage, Current, Battery capacity and Charge Time will display on the screen.
This DC motor driver module is based on the popular L298N Dual H bridge IC. It integrates all necessary components to drive 2 DC motors at up to 2A each, with a voltage between 5 and 35V DC or 1 Stepper motor with a microcontroller like Arduino or esp8266.
Evola USB Infrared Transceiver is an IR remote control emitter / receiver with built-in USB communication based on ATMega32U4 with the Arduino Leonardo bootloader. This board simply connects to a USB port on a computer, and let you capture and study remote control commands.You can view infrared signals on a logic analyzer, capture, play and replay remote...
