Flipper Zero Add-On: CANBus

The Flipper Zero is a portable multi-tool for pentesters and digital hobbyists. It can hack radio protocols, access control systems, hardware, and more. It's fully open-source and customizable, so you can extend it in whatever way you like.

The Flipper Zero Add-On: CANBus and associated MCP2515 CAN bus app allows you to interact with a CAN bus network.

Controller Area Network (CAN), is a communication system designed for devices to talk to each other. It’s most commonly used in cars where it allows all the electronic control units (ECUs) to chat with each other.

Instead of a continuous flow of data, CAN bus sends information in short messages. Each message has an ID that tells the other devices what kind of data it is. This makes it easier to find specific information.

Not all messages are equal. Some messages are more important than others. CAN bus lets important messages get sent first, which is crucial in situations such as when the anti-lock brakes need to talk to the engine right away.

Using the Flipper Zero Add-on: CANBus, you can read transmitted messages, watch bytes from every node in the network, and catch any message or package and resend it, or send other data to the same address. The app is a tool for analyzing and viewing Internet-of-Things traffic in CAN bus networks, error detection and peripherals control in a CAN bus network. You can also analyze the traffic of the signals and even replicate them to control peripherals in a CAN bus network

MCP2515 is a stand-alone Controller Area Network (CAN) controller that implements the CAN specification, Version 2.0B. It is capable of transmitting and receiving both standard and extended data and remote frames. The MCP2515 has two acceptance masks and six acceptance filters that are used to filter out unwanted messages, thereby reducing the host MCU’s overhead. The MCP2515 interfaces with microcontrollers (MCUs) via an industry standard Serial Peripheral Interface (SPI).

The Flipper Zero Add-On: CANBus is covered by a 3-month manufacturer's warranty covering all its original parts and labor against any factory and operation defect.
