SparkFun Engineering Tools

Interface Development Tools This is a breakout board for the SP3485 RS-485 transceiver IC which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver so it can only communicate one way at a time but it can reach transmission speeds of up to 10M

Interface Development Tools This is the SparkFun USB to Serial Breakout for the FT232RL a small board with a built in USB to serial UART interface. This little breakout is built around the FT232RL IC from FTDI with an internal oscillator EEPROM and a 28-pin SSOP package thi

LED Lighting Development Tools 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 s

LED Lighting Development Tools The SparkFun Qwiic LED Stick features ten addressable APA102 LEDs making it easy to add full color LED control using I2C. Write to individual LEDs to display a count in binary or write to the whole strip for cool lighting effects. You can even add

Development Boards & Kits - AVR Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to soft
