I2C Protocol Analyzer
EasyI2C
-
It's simple to find an I2C-style bus within arm's reach. Every computer, monitor, television and cell phone has it. Most microcontrollers directly support this protocol as well. Even so, the I2C protocol has many subtle nuances that are hard to grasp and easily forgotten. EasyI2C (TM) helps you to figure out exactly what is happening, without having to examine huge waveform trace capture files or set up complex tests.

The SparkFun SAM-M8Q GPS Breakout is a high quality GPS board with equally impressive configuration options. The SAM-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery, you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

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.
