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.

SparkFun GPS Breakout
ZOE-M8Q (Qwiic)
-
The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, 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.
