USB to TTL converters are an essential for prototyping - they provide a direct interface with the target device. This module connects to your computer USB port and there are 4 wires which connect with your target device. This model is the bare version of our enclosed model.
You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!
This is an awesome little microSD USB reader. Just slide your microSD card into the inside of the USB connector, then stick this into a USB port and the card’s contents will pop up on your computer. Very sneaky - we love it! This little guy is great for pulling data logs off microSD media. This reader also includes an indicator LED which will light up if a microSD card is present. This device is completely plug-and-play, so no drivers needed.
Are you low on I/O? No problem! The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals, so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.
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.
This is the FemtoBuck, a small-size single-output constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V while the dimming control can be either accessed via PWM or analog signal from 0-2.5V. This board is based off of the PicoBuck LED Driver, developed in collaboration with Ethan Zonca, except instead of blending three different LEDs on three different channels the FemtoBuck controls just one.
This tiny breakout board for TI’s DRV8833 dual motor driver can deliver 1.2 A per channel continuously (2 A peak) to a pair of DC motors. With an operating voltage range from 2.7 V to 10.8 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering small, low-voltage motors.
6 pin SOT-23 to DIP adaptor. Created to take SOT23 of various pin sizes breakout to DIP. This will work with 3-pin MOSFETs, BJTs, Voltage Regulators (SOT-23-5), and various other Micro6, Micro5, etc packages.
This is an evaluation board for the Silicon Laboratories Si4703 FM tuner chip. Beyond enabling you to tune in to FM radio stations, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.
This is a simple 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.
