What's With These Inconsistent Pins?

(1/3) > >>

Max Holdcroft:
I'm looking at the datasheet for the ISP_1507 BLE module. In the reference schematic for the module, they use a 10 pin 0.5mm pitch FFC, but for the schematic I have the pins are all different. In the example schematic, they have two ground pins, but in my schematic there aren't any, but there IS an additional "anchor" pin? What is this?
I appreciate any help!
Max :)

Gyro:
Please stop creating a new thread for every question about this module. That's not how this forum works and will put you on the wrong side of the Mods!

Not just the mods.

Also the same programming connector is attached here, but I'm not sure if there still is an issue with attachments getting mixed up.

I know the OP is young according to his profile, but when you want help you need to be more precise.

@Max Holdcroft you mention "my schematic", so where is that one? Provide as much information as possible when asking for help. We are not mind readers, nor do we have crystal balls.

And like Gyro pointed out just do it in a single thread, and when you don't get the answers you are looking for, don't think that trying again in a slightly different form in a new thread will get you that answer.

Gyro:
I hadn't realised that the OP was so young. @Max, yes please keep everything in the same thread, then people have a much better chance of 'connecting' your questions.

I read your post again and challenge you to think about this last bit yourself. Do some searching online to find pictures of the bare connectors and imagine what this anchor pin would be.

Here is a starter. https://www.molex.com/en-us/products/connectors/ffc-fpc-connectors
