Dual stepper motor driver shield can drive 2 stepper motors at the same time by Arduino. It can work with the power supply from 4.75V to 30V. High accuracy controlling can be supported by Arduino for CNC milling machine.
If you are searching an ultrasonic ranging module, the HC-SR04 is good choice: Its stable performance and high ranging accuracy make it a popular module in electronic market. It's cheaper than an IR range finder with similar range accurancy and distance.
Iteaduino Tiny is a mini development board based on Attiny85 master, which is cheap, compact and easy to use with low power consumption. The mainboard is a derivative board with reference to digispark design, and it supports use of specific Arduino IDE and uses Arduino syntax for programming which is quite convenient.
ESP8266 module ESP-201 with standard 2.54mm headers, making it almost breadboard friendly (alsmot as there as some pins that don't fit, but it can be fixed easily).
Like the ESP-01 but dislike the few IO ? look no more, don't bother with smd board and try this one.
The Rainbow colorful case is crafted out of high quality acrylic layers with a transparent top and base. It's smooth, slick, and durable and because of its multi-color finish, stands out in almost any room. You simply stack the layers around your Raspberry Pi Model B+ to protetct it from the outside world. The case is lightweight and can be mounted to any...
If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. This logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 4 pins on the high side to 4...
