In the meanwhile, does this topic help? [https://easyeda.com/forum/topic/Struggling-with-modules-e8a029f2c53c43f499086873ada0a575](https://easyeda.com/forum/topic/Struggling-with-modules-e8a029f2c53c43f499086873ada0a575)

@andyfierman thanks for your reply. I had read previously the post, but didn't found an answer for the problem. When inserting several times an schematic module, it applies the prefix you write down, and it works perfectly. It doesn't work in the same way when you insert several times the PCB module. As the components have pads, those pads usualy take the name of the component plus the number, so the problem comes when EasyEda rename the components when inserting the PCB module, but the pads remain the same name than the module. Check carefully the resistor array of the bottom, original name in PCB module was RN1. Prefix used when inserted was "A", so all components had an "A" in front of the name, but the pad remained with the same name than the module, as result, when it is inserted several times... all modules inserted share the net and doesn't work correctly.

I have posted a bug report about this problem: [https://easyeda.com/forum/topic/Update-PCB-or-Import-Changes-when-used-with-Modules-appears-to-be-broken-b55da0af9a2b49df8c3b5c8d80136e6e](https://easyeda.com/forum/topic/Update-PCB-or-Import-Changes-when-used-with-Modules-appears-to-be-broken-b55da0af9a2b49df8c3b5c8d80136e6e)

I yes!!, I got it working, great! I didn't see the checkbox when importing changes, didn't know that was the key. Thanks andyfierman

@warloofer, We have both learned something useful today! Deep Joy. :)

Hi people, I have created an EasyEDA Extension to allow reuse and multiple instantiation of schematic and PCB modules! Code and instructions are [here](https://github.com/ppeetteerrs/EasyEDA-Tools)!

@ppeetteerrsx, Perhaps you could be so lind as to describe what your extension does that the existing EasyEDA process does not, or what problem with the current EasyEDA Schematic and PCB Module handling process your extension solves?
