1. The power position of the pins on one side has been adjusted. V1.3 is consistent with V1.2 and is no longer compatible with V1.1 2. The model of TI power supply chip has been adjusted 3. The CLK pin of has been adjusted to SRCC clock pin (it can adapt to more IP cores) Please note: the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!
