This is what is reworked on Kess (SE137-C1)…Here you go.
1.the left upper corner and the lower right corner notch size is not the same
2.More than buzzer
3.WFs = Infineon, BCR112 NPN Digital Transistor
4.27E = ON Semiconductor NUP2105LT1G
5.6DW = NXP BC817,215 NPN Bipolar Transistor
6.A6c =MMUN2113LT1G / MMUN2113LT3G
7.K5B = BC807-25-7-F PNP Bipolar Transistor
8.Using imported Japanese Murata filter NFE61PT472C1H9L
Note: New board will be released soon!
100% Tested OK. You can use with relief. Look here
