CircuitGizmos provides products for sale that are designed and produced by the creative minds at CircuitGizmos, USBmicro, Amber Waves Electronics, and other fun sources of clever engineering.
Here you can purchase the USBmicro U401 and U421 USB interface that has support for SPI, LCD, 1-wire, stepper motor control, input, and output.
CircuitGizmos sells the Maximite Computer in the form of the CGMMSTICK1 that you can add as a module to a circuit board or you can use it with a solderless breadboard. The Maximite runs BASIC and supports a display on VGA. A keyboard can interface to the Maximite as well as I2C, SPI, and serial devices.
CircuitGizmos also sells the unique USBPIR USB motion detection module and home automation and security software made to work with these devices. Other CircuitGizmo items include the DS1822 temperature sensor, relays, LEDs, resistors, project boxes, small screw terminals…
U451 USB Relay Interface w/cable
Dual Relay USB interface with 6 o.c. outputs
The U451 provides a simple digital i/o interface for the PC (Win/Linux) or Mac (OSX) . Two relays, six transistor outputs, and eight i/o lines from the microcontroller are provided. Commands can be sent to the U451 that change the eight i/o lines from input to output. I/o lines can be individually selected as inputs or outputs. The U451 supports commands to read the ports, and if the ports are set to output, to write to the ports.
The U451 has all of the firmware features of the U401 and U421.
The U451 is an assembled and tested circuit card that is 2.8125 inches (72mm) long and 1.625 inches (47mm) wide. The U451 has 4 mounting holes.
The U451 interfaces to the PC (Win/Linux) or Mac (OSX) via the USB port. An application on the PC (Win/Linux) or Mac (OSX) controls the U451. The U451 does not use any custom drivers, just the drivers that are a part of the operating system. Custom software can be developed to use the U451, or the applications that have been created as examples here can also be used.
Fits in the project enclosure sold here at CircuitGizmos!
