NOTE – Before soldering switches, please test all keys (use tweezers or iron wire) and LEDs(If PCB can or not support 2pin single colour led or RGB led) to make sure all functions work properly. BEFORE soldering, if the PCB has any key problems, we can re-ship a new one. AFTER soldering, we are sorry that we can’t re-ship any replacements. However, we are able to help you to repair it (buyer needs to pay for the returning shipping fee). If you order our products, we assume that you agree with the above terms.

The key at the left bottom of the PCB is FN key(combination key). Normally, it won’t active when you test the PCB with the key tester. When you press fn + another key, it will have key-value, Pls pay attention:)
