rMP3 Connectors
Arduino Connector
The default connections for the Arduino Connector are as follows:
- Serial
- Pin 6: Serial receive on Arduino, transmit on rMP3
- Pin 7: Serial transmit on Arduino, receive on rMP3
- SPI
- Pin 8: SPI chip select (https://home.roguerobotics.com/CS - active low)
- Pin 11: SPI MOSI (Master Output, Slave Input)
- Pin 12: SPI MISO (Master Input, Slave Output)
- Pin 13: SPI SCK (SPI Clock)
All of these pins have an associated jumper pad just beside the connector which you can use to reroute the signal. You will need to physically cut the jumper between the pads.
You only need to use one of the two interfaces at a time (i.e. serial vs. SPI).
INFO: The SPI interface is not available in rMP3 firmware version 100.01.

Other Connectors
JP5
When JP5 is jumped, the FTDI connector will be used as the power supply for the board.
WARNING: JP5 must not be jumped if the FTDI connector is used at the same time as another external supply is connected.
JP6
JP6 is used when updating the firmware. The “Manual Update” mode is recommended. This will put the rMP3 into bootloader mode.
DNU
The DNU connector is used for manufacturing only.
