Digital logic is the foundation of every task that a computer can do, so it's no wonder that in order to fully understand how computers and other digital electronics work, you need to be familiar with logic gates. The problem is that logic gates aren't the most "hands on" subject, until now. The SparkFun LogicBlocks Kit allows you to play with logic gates by literally plugging one into another and watching the progression of an input to an output! Each LogicBlock represents a different logic...

The SparkFun Micro OLED Breakout Board breaks out a small monochrome, blue-on-black OLED. It’s "micro", but it still packs a punch – the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next Arduino project, displaying diagnostic information without resorting to serial output, and teaching a little game theory while creating a fun, Arduino-based video game. Most important of all, though, is the Micro...

Running out of memory space in your Arduino project? The SparkFun microSD Shield equips your Arduino with mass-storage capability, so you can use it for data-logging or other related projects. Communication with microSD cards is achieved over an SPI interface. The SCK, DI, and DO pins of the microSD socket are broken out to the ATmega168/328's standard SPI pins (digital 11-13), while the CS pin is broken out to Arduino's D8 pin. If you decide to use one of the many open source FAT libraries...

This is a unique board recommended by a SparkFun customer. When playing with microSD, you sometimes need to view what the SPI traffic is doing, whether for hacking or debugging. The SparkFun microSD Sniffer allows you to hook up an external device, such as a logic analyzer or microcontroller, to view what signals are being passed back and forth. Insert one side into a regular uSD socket and a uSD card into the on-board socket, simple as that. All necessary pins are broken out to an 8-pin 0.1"...

The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. With the on-board 64x48 pixel OLED, you can use the MicroView to display sensor data, emails, pin status, and more. It also fits nicely into a breadboard to make prototyping easy. The MicroView also has a full-featured Arduino library to make programming the module easy. In the heart of MicroView there is ATMEL’s ATmega328P, 5V & 3.3V LDO and a 64x48...

The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. This USB programmer connects directly to the MicroView and lets you not only program the module, but use it to interface with your computer, Rapsberry Pi, or other USB device. The programmer has both male and female headers which allow it to be plugged into a MicroView module and a breadboard at the same time, making prototyping quick and easy. If you...

The TB6612FNG Motor Driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes: CW, CCW, short-brake and stop. The two motor outputs (A and B) can be separately controlled, and the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode. Logic supply voltage (VCC) can be in...

This is a simple 5V Op Amp breakout board, set up as a 2-stage amplifier with a gain of 100 (gain of 10 for each stage). The on-board trim pot sets the signal level between the stages, not the feedback path. The bandwidth is set to 15.9kHz by a pair of feedback capacitors, or over 100kHz with the caps removed. The LMV358 opamp can source up to 160mA and works well as a low impedance driver/buffer. Documents: Schematic Eagle Files Introduction to Op Amps with LTSpice Datasheet (LMV358) GitHub...

The SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 32GB. The OpenLog can store or "log" huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes. The SparkFun OpenLog uses an ATmega328 running at 16MHz thanks to the onboard resonator. The OpenLog draws approximately 2-3mA in idle (nothing to record) mode. During a full...

This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side. We often use this board to allow a microcontroller control servos or other motors that use a higher voltage than the...
