RA-08H LoRa dev board

I have bought one of the LoRaWAN RA-08H Development Board Integrated RP2040 with 1.8 “ LCD for Long Range Communication (868Mhz/915Mhz.

Nice looking board, and seems it would be very useful for testing LoRa systems.

however, appears to be in compressed format, and I cannot find a suitable file conversion. That is files PCA9557.h and PCA9557.cpp.

Is there an update to this library?
