About the Sensor to-CAN PCB

Sensor to-CAN is an open source PCB design by Sarbf1, published on GitHub under the Custom license license. It is a 4-layer board measuring 46 × 20 mm, with 45 components from 19 distinct parts.

Other key parts include the NCS20074DTB, MCP2518FD-xQBB, MCP2542FDxMF and SHT4x. By type, the board carries 16 resistors, 10 capacitors, 6 connectors, 6 diodes, 4 ICs and 2 switches.

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

From the project

A HAT for Arduino nano, to Connect nearly any sensor and send its walues using CAN or NMEA bus

This is an early version. The hardware is drwan, but not checked or tested. The four layer board is slightly larger than the arduino nano R4, as i have added a shield ring (in case of use in high EMV areas such as in electric vehicles).

Also the code has not been written yet, but will follow.

The goal is to have a HAT board for on a Arduino Nano R4, that can connect to any sensor (3.3V 500mA, 5V 1A or Vin). The sensor vaule (any voltage, or current input, selectable with a jumper) is processed by the arduino R4 and the sent using CANbus, using NMEA2000 protocol. It has three LEDs that can…
