Why the board is photographed only from one side?
- ilyt 3y agoI assume because routing on the other looks ugly xD
- Karliss 3y agoIf the PCB was connecting two connectors together with testpoints in the middle that might have been the case. But it is much simpler than that. Right above photo there is a gif showing that all the pins for one connector are connected to battery, while other connector connects to LEDS and afterwards ground.
- ThatPlayer 3y agoLooks like a single layer PCB
- ilyt 3y agoIt does not look like single layer PCB in the slightest and it is probably and at least 2 side
- _Microft 3y agoI think it is either a single layer board or the back side is empty anyways. The complexity certainly does not require a board with two or more layers. Here is how it is made up: Positive pole goes to the pins of the connector on the left-hand side, negative pole to the ground fill (look closely to the right connection at the battery and you will see how it connects to the area with the lighter shade of green on the board - this is a copper area shining through the green solder mask). On the right hand side, the different pins of the connector are wired to the test points, resistors and diodes which at the other end connect to the ground fill. Now if a cable is plugged in both sockets and if there is a connection on a particular pin of that cable, the circuit for the respective LED is closed and it lights up.
- caydenpiercehax 3y agoIt's a 2 layer PCB. I put all the components on one side for simpler PCBA. The other side of the board is pretty boring - just a ground plane and a couple traces. Like others said, this whole thing could be done on a single layer if you wanted.
