SparkFun Photodetector Breakout
MAX30101 (Qwiic)
-
The SparkFun Photodetector Breakout is an updated version of the SparkFun Particle Sensor Breakout includes the MAX30101, a highly sensitive optical sensor and successor to the MAX30105 and MAX30102. The MAX30101 Breakout utilizes a photon detector to measure the amount of returning light that is reflected back from the LEDs. This is useful for various applications like particle (i.e. smoke) detection, proximity measurements, and even photoplethysmography. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1" spaced pins in case you prefer to use a breadboard.

Dual Wide Range Power Monitor
LTC2992
-
The LTC®2992 is a rail-to-rail system monitor that measures current, voltage, and power of two supplies. It features an operating range of 2.7V to 100V and includes a shunt regulator for supplies above 100V. The voltage measurement range of 0V to 100V is independent of the input supply. Two ADCs simultaneously measure each supply’s current. A third ADC monitors the input voltages and four auxiliary external voltages. Each supply’s current and power is added for total system consumption. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I2C interface. Shutdown mode reduces current consumption to 25μA typically.

Bi-Directional Level Translator
IFB-10001
-
Easily connect Arduino or other 5V microcontrollers to ~3.3V sensors. Based on the TI TXB0108 auto-sensing, bi-directional level translator, this module provides access to all 8 channels of the TXB0108 and has a built-in 300mA LDO with 200mV max dropout voltage at full load. Regulated 3.3V output allows this single board to both interface withandpower 3.3V sensors. An important feature of this module is the ability to operate SPI and other digital lines (not including I2C) at high-speed, whereas the 'NXP level shifter' maxes out at 400kHz and resistor dividers fail much earlier. The TXB0108, integrated with the LP3981 LDO, provide a fast, reliable solution to mismatched interface voltages that exceeds the performance of other solutions.

SparkFun 16 Output I/O Expander Breakout
SX1509
-
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. This breakout is similar to a multiplexer or "mux," in that it allows you to get more IO from less pins. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.
