SparkFun Artemis OpenLog Hardware Schematic
Schematic for the SparkFun Artemis OpenLog, a data logger featuring the Artemis module, ICM-20948 IMU, and integrated LiPo charging via USB-C.
Overview
This schematic details the hardware design for the SparkFun Artemis OpenLog, an open-source data logging platform. The circuit is centered on the SparkFun Artemis module (Ambiq Apollo3) and integrates a TDK InvenSense ICM-20948 9-axis IMU for motion tracking. Key components include a WCH CH340E for USB-to-serial communication, a Microchip MCP73831 for LiPo battery charging management, and a Diodes Inc AP2112K-3.3 voltage regulator. The design also features a microSD card slot for storage, a Qwiic connector for I2C expansion, and onsemi BSS138 MOSFETs for logic level shifting.
Use Cases
- High-speed data logging
- Motion and orientation sensing
- Remote environmental monitoring
- Battery-powered IoT prototyping
- Embedded system development with the Artemis module
