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 Color Maximite 2 Computer in the form of the CG RetroMax. 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.
The Sensor.Engine:Micro is a great way to augment a solderless breadboard and interface to things like the small boards in the 37 sensor kits. This is an easily programmed STEM controller.
CircuitGizmos also sells the unique USBPIR USB motion detection module and home automation and security software made to work with these devices.
NONchuk PCB
The NONchuk board provides a way to interface joysticks and other devices to the RetroMax. The intention is to use the I2C port on the NONchuk to connect to the Nunchuk interface on the RetroMax (or CMM2).
The NONchuk allows the Nunchuk port of the RetroMax to connect to joysticks and several other devices. Since there are a variety of different devices that can be connected, the NONchuk uses a MicroMite chip (the '170 with MMBasic installed) to run code for the task.
The NONchuck has a console port that can be used as the serial interface for programming the MMBasic code specific to how the NONchuk will be used.
The NONchuk features:
• Based on MMBasic '170 so it can be user re/programmed
• Support Atari (digital/switch) joystick
• Support PC (analog/potentiometer) joystick
• Operate as I2C slave interface
• Operate as serial interface
• Support 16 key keypad
• Support rotary module
• Support analog joystick module
The NONchuck board could also be used as a stand-alone MicroMite ('170 chip) board. For example it could be used with a joystick and various pins from the microcontroller could control relays, LEDs, etc.
The NONchuk has an on-board 3.3V regulator if the source power for the board is 5V. The board will work from either 5V or 3.3V. The MicroMite on the board runs at 3.3V. If 3.3V is present to the board the power LED will illuminate. Power and ground connections can be found on several of the connection points.
On either side of the NONchuk microcontroller (MicroMite) are a row of connections that connect one to one to the 28 pins of the MicroMite. These provide simple/easy access to all of the MicroMite pins.
