We could talk about how the Zinc used in these nuts is only from the finest old-growth Zinc trees from across the globe and is hand picked only at the peak of the season. Or how they are expertly hand-ground by a 6th generation master grinder. And how every nut passes a rigorous 19-point inspection process at each step of the process. And how each nut's dimensional variations can only be measured on the sub-atomic level. We could say all that, but it would be a lie. These are standard 4-40...

    This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125 degree, the cable is jacketed in PVC so we suggest keeping it under 100 degree. Because they are digital, you don't get any signal degradation even over long distances! The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and...

The MAX31820 ambient temperature sensor provides 9-bit to 12-bit Celsius temperature measurements with ±0.5°C accuracy over a +10°C to +45°C temperature range. Over its entire -55°C to +125°C operating range, the device has ±2.0°C accuracy. The device communicates over a one-wire bus that, by definition, requires only one data line (and ground) for communication with a central microprocessor. In addition, the device can derive power directly from the data line, eliminating the need for an...

The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on...

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows...

Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface. This tiny little board does all of the neat-o Arduino tricks that you're familiar with: 9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as...

    John Jay based in Georgia, USA, is a retired engineer who designed some boards for the Raspberry Pi to help his partner to learn Raspberry Pi. Although at first it was a small act that just for his friends, but with the growing people in the open-source community participating, more and more people find that these packages really works. So, he decided to releases these kits. Cooperated with Elecrow, these packages have been produced quickly. And here with Elecrow, we...

Combines the power of screw shield and prototyping shield. This Proto Screw shield offers a better way to do prototyping. The Screw terminal can be screwed directly to the terminal on the thread and is reliable and convenient. It can be plugged into the Arduino controller. You can use this shield to save yourself from the bad port connection. Feel secure with this arduino-compatible screw shield. The prototyping shield provides a fast prototpying area for projects. It features a LED (D13) and...

Quadstepper Motor Driver Board Description: The Quadstepper motor driver board allows you to control up to 4 bipolar stepper motors simultaneously using logic level IO pins. Each motor driver has an output drive capacity of 35V and 1Amps. The board is capable of driving motors in full, half, quarter, eight, and sixteenth-step modes. The logic levels are selectable between 3.3V and 5V by way of a jumper. The bus header allows you to control all four motors with only 6 IO pins by...
