OBD-II CAN Bus RF Dev Kit

OBD-II (short terms for On-Board Diagnostics, Second Generation) is a set of standards for implementing a computer-based system to control emissions from vehicles. Also, it can be explained as a vehicle's built-in self-diagnostic system. When your vehicle has an internal issue, normally it would pop up a malfunction indicator light on your dashboard, telling you to visit the broken mechanic and get the problem fixed. In the past, this light would just light up to indicate the vehicle is broken, but it was not possible to identify where the issue was. Nowadays, the OBD-II built inside vehicles, allows you to identify the exact problem of the vehicle by connecting an OBD-II reader to the OBD-II 16-pin connector built inside the vehicle. Through this, it has been possible to read OBD-II codes, also known as Diagnostic Trouble Codes (DTCs) which help understand the issues, and there is no need to completely disassemble the vehicle.

Usually, there is an OBD-II interface on the vehicle for the user to read some data through the CAN-Bus interface, such as vehicle speed, engine speed, and oil temperature, etc. And 'RF' stands for 'Radio Frequency', it can help to transmit data through hundreds of meters without CAN-Bus or any cable. With the RF device kit, the data about vehicles can be transmitted wireless to other devices like microcontrollers.

OBD-II RF Dev Kit includes two parts: the transmitter and the receiver. The transmitter is inserted into the OBD-II interface of the vehicle, integrating with the CAN-Bus interface and RF communication. That means it can transmit the data read by CAN-Bus to the remote end through radiofrequency. The receiver is a Serial RF Module, which can send the data from the receiving end to the microcontroller through the serial port.

Additionally, if you want to build some interesting projects about using vehicle data and remotely processing with it, we highly recommend you use this OBD-II RF Dev Kit for your projects. Also, we have OBD-II Serial CAN Bus Dev Kit for fast and stable data transmission and an interesting project about car "hacking" using CAN bus via Wio Terminal, which is really fun.
