Here is the value/placement and BOM of the components of Miss Parker Plus extension PCB.
The PCBs are dual layer ones and they have been manufactured by a specialized company, read the release note for more details about the files.
Note that the three boards have been validated now. The extension board is suffering some bugs though (lines inverted forbidding to use external mode of the AL3201) so if you want to build one, please contact Whity first.
