CAN-BUS Shield v2
Sold outWith its long travel distance, great communication speed and high reliability, CAN-BUS is one of the most common industrial bus.
Overview
It is commonly found on modern machine tools and as an automotive diagnostic bus.
Thanks to the CAN-BUS, makers are able to hack their cars!
It adopts MCP2515 CAN-BUS controller with SPI interface and MCP2551 CAN transceiver to give you Arduino CAN-BUS capability. Default pinout is OBD-II and CAN standard pinout can be selected by switching jumpers on DB9 interface.
Moreover, it has the TF card slot for data storage and the CS pin that can be set to D4 or D5.
The INT pin can also be set to D2 or D3 by switching jumpers on the back of the shield.
CAN-BUS Shield Works perfectly with Arduino UNO (ATmega328), Arduino Mega (ATmega1280/2560) as well as Arduino Leonardo (ATmega32U4).

I have prepare home Automoation project using Arduino nano esp32
Home file servers can be very useful for people who work across multiple devices and want easy access to their documents. And there are a lot of DIY build guides out there. But most of them are full-fledged NAS (network-attached storage) devices and they tend to rely on single-board computers. Those take a long time to boot and consume quite a lot of power. This lightweight file server by Zombieschannel is different, because it runs entirely on an Arduino. An ESP32 is a microcontroller with built-in connectivity (Wi-Fi and Bluetooth). Like all MCUs, it can “boot” and start running its firmware almost instantly. And while it runs, it will consume much less power than a conventional PC or a single-board computer. Zombieschannel’s project proves that the Arduino Nano ESP32 is suitable for a file server — if your expectations are modest. The hardware for this project consists of a Nano ESP32, an SD card reader module, and a small monochrome OLED screen. The SD card provides file storage and the OLED shows status information. Most of the work went into writing the firmware, which Zombieschannel did with assistance from ChatGPT. That has the Arduino hosting a basic web interface that local users can access to upload or download files. Zombieschannel also created a command line interface that provides more comprehensive access via a serial connection. This does have limitations and the transfer speeds are quite slow by modern standards. But the file server seems useful for small files, like text documents. Zombieschannel plans to design an enclosure for the device and it should tuck unobtrusively into a corner, where it can run without drawing much power.
