Magnetic Field Sensor with DRV425
概要
- TI製高感度磁界センサDRV425を使用した高感度磁界センサ基板です
- 高感度±0.5mT、帯域最大47kHzで磁界をアナログ出力として得ることができます
- シャント抵抗(既定値32ohm)を変更することで±0.1mT~±2.0mTまでの範囲で感度を変更することができます
- 地磁気、電流センサ、磁石検出や位置センサの用途に使用することができます
- 電源は3.0V～5.5Vで使用できます
- センサ出力は電源電圧/2を0mTとして双方向の磁界を検出できます
- サイズ14mm x40mm、穴サイズM3x2、間隔22mm
注意
- 電流センサとして使用する場合は2つDRV425を使用して地磁気をキャンセルさせる回路構成にしてください

Questions
How big is the Magnetic Field Sensor PCB?
It measures 40 × 16 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Magnetic Field Sensor use?
16 parts, built around the DRV425RTJ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Magnetic Field Sensor KiCad files?
From the meerstern/Magnetic_Field_Sensor repository on GitHub, at the commit this page was made from: the board is cs.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Magnetic Field Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask meerstern before reusing the design.
