Description
This is the same Allegro A1101 unipolar hall effect sensor that has always been supplied with the V1.x eChook nano kits, but on a PCB making it far easier to mount, use and connect.
V2.0 kits include these as standard.
- On board LED to indicate when a magnet is detected for testing (or you can cut a jumper on the back of the board to disable this)
- M4 mounting hole to bolt to a bracket.
- JST-PH 2.0 Connector, with harness side and pigtails to integrate into your wiring harness robustly.
Electrical Specification:
Operating Voltage: 5v
Output:
– No magnet: 10KΩ Pull Up .
– Magnet present: Pulled down by A1101 open collector.
What’s in the box:
1x Magnet Sensor PCB
1x JST-PH 2.0 connector pre-wired with 30cm 24AWG wire
As with everything eChook makes for Greenpower, this board is open source. The KiCad design files are available here: https://github.com/eChook/magnet-sensor-board/
