About the Current Sensor Breakout

Current Sensor Breakout is an open source PCB design by antevens, published on GitHub under the SHL-2.1 license. It is a 2-layer board measuring 80.1 × 49.4 mm, with 14 components from 7 distinct parts.

Other key parts include the MCP3423 and ACS37002. By type, the board carries 6 capacitors, 3 ICs and 3 connectors.

It belongs with the dev boards & breakouts and sensors designs in this gallery.

From the project

A Relay PCB with a socket for a Raspberry Pi or Nvidia Jetson to control everything on a boat

Boatcontrol is an open hardware design for a marine grade SMART/IoT electrical distribution panel and electronics platform (boat) controller.

It's an I/O breakout board capable of switching 32 onboard laching relays and optionally 32 momentary/laching relays using addon boards switchnig up to 60A AC/DC 0-400V per circuit.

The "smart" part is provided by either a Raspberry Pi HAT or a Nvidia Jetson (Nano/Xavier NX) either of which can be mounted on the board.
