OpenLog Artemis Kit - set with a data logger

Description

Set with OpenLog Artemis data logger. The set includes a USB type C cable, a LiPo 1250 mAh battery, a 1 GB microSD card and all the necessary Qwiic cables to connect the attached boards. The kit also includes an I2C Qwiic Mux Breakout expander and a Qwiic Scale strain gauge module to enable access to data from any Qwiic series sensors.

OpenLog Artemis is a data logger that comes pre-programmed to automatically record data from IMU, GPS, serial communication modules, and various pressure, humidity and distance sensors. OpenLog Artemis automatically detects, configures and logs Qwiic sensor data. After enabling the module, all incoming data is automatically saved in a file with a baud rate of up to 921600bps. OpenLog Artemis also allows analog data logging via four ADC inputs. Voltages up to 2 V can be recorded with 14-bit precision, up to 1900 Hz for one channel and 1000 Hz for all four channels. Additionally, thanks to the built-in clock, all data can be marked with the login time.

Qwiic Mux Breakout is a module of an 8-channel I2C expander based on the TCA9548A chip. The module has Qwiic connectors and enables communication with multiple I2C devices that have the same address.

Qwiic Scale is a module with a NAU7802 24-bit ADC converter. It enables reading data from strain gauges and scales. The NAU7802 amplifies the read resistance of the strain gauge and converts it into a digital signal.
