(Customer feedback) Launch M-Diag Lite PCB board compare with Easydiag

I bought Launch M-Diag LitePlus and took it apart to check the PCB board. Compare with Easydiag, mostly same but better contacts used in the diagnostic socket.

Here share with you some Launch M-Diag Lite PCB real pictures:

Inside Launch M-Diag, I found a two-board design, the boards were tightly connected to each other by a pad of twenty jumpers.


One board with a multiplexer and a processor, and the other with a Bluetooth module and power system. And yes, there is a USB connector, just like LAUNCH EasyDiag.


On Launch M-Diag Lite main (processor) board there are the following markings:

LAUNCH 10200716

DBSCAR_MAIN_STM32F207 – name of the board and the processor used

2015.05.29 – production date

V1.00.000 – version of the board


On the “communication” board there are the following markings:


V1.00.000 – version of the board



2014.11.08 – production date

The main board has:


Processor STM32F207IGH6

Multiplexer JV700

Also on the board contacts are similar to the connection of the service connector.

The communication board uses only two controllers in the Bluetooth module:
