Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.
## Information
This board has no marking on the front side, only something that looks like PCB manufacturing info on the back; thus it was named based on these symbols.
It can be found in 'LSC Smart Connect Outdoor LED Strip', and is likely custom-made for this product.
The pinout was established by writing to and probing consecutive GPIOs, using the generic board definition.
Pins marked with '?' are currently unknown, with a possibility of being CEN. Pin 22 (P1/D14) is also not confirmed.
