is there any documentation to RBM33G board? I have some questions:
- J601 connector is containing UART2 and UART3 - they are +/-12V RS232, or TTL?
- in the configuration there is only Serial0 and Serial1, but on the hardware there are 3 ports
- where are the GPIO ports?
- what is J4 port?
- what is J19 port?
- what is J700 port?
