Main Components of Bluetooth OBD2 Scan Tool

Resistor: there are many main functions of resistor in the circuit of OBD scan tool. Such as shunt, current limiting, voltage dividing, bias, filtering and impedance matching.

CERALOCK: let a certain frequency signal pass through, block other frequency signals to achieve the purpose of selection. When the signal frequency and the natural frequency of the harmonic oscillator are equal, the signal passes smoothly. When the frequency away from the natural resonant frequency tries to pass, it is like a large impedance.

Capacitors: there are many functions of capacitors. It can make the output of the regulator uniform and reduce the load demand. It can also meet the current variation of the OBD2 scan tool drive circuit. And avoid the coupling interference between them. It also has the function to filter high frequency and low frequency.

CAN transceiver: It is the interface between the controller area network protocol controller and the physical bus. It provides differential transmit capacity to the bus and differential receive capacity to the CAN controller.

Diode: rectifying, freewheeling and isolating the circuit of OBD scan tool.

Bluetooth module: it is a communication component between OBD2 scan tool and external devices. The Bluetooth name and MAC address of OBD scan tool can be realized by customizing the Bluetooth module.

Resistor array: It can replace multiple single resistors. Compared with single resistor, it can reduce the installation area. In other words, it can occupy less points of the OBD scan tool circuit board. It can also reduce assembly time and cost.

ARM microprocessor: processing instructions and exchanging information with external memory and logic unit.

LED indicator: it can display connection status of OBD2 scan tool.

Fiberall can provide customized service of OBD2 scan tool. If you need to modify PCB or replace some parts, please contact us.
