SparkFun XBee Explorer Dongle enables the communication between your computer and any XBee device, as in case of any XBee device, without any cables!

The module is compatible with Series 1, Series 2.5 and standard Pro version with voltage regulator functioning with the current up to 500 mA.

SparkFun DataLogger IoT - 9DoF is a pre-programmed data logger to automatically log IMU, GPS and various pressure, humidity and distance sensors - all without having to write a single line of code! DataLogger automatically detects, configures and logs Qwiic sensors. It is specifically designed for users who only need to capture a large amount of data in a CSV or JSON file and return it to their larger project.

The amplifier with high efficiency, in case of 12 V power supply can output 10 W + 10 W power.

The ADS1115 is an external 16-bit ADC + a built-in programmable gain amplifier (or PGA), which can be very useful for certain Arduino and ESP8266 projects. This is ideal when more resolution or more analogue pins are required. You get better accuracy, as well as relieving the processor of this burden.
