Changes
MIPI and PPB flat-ribbon connectors have been exchanged with a pin-compatible less fragile part
Removed CAN bus termination on Skynode. Now Skynode adheres to the CAN standard, where the user is required to terminate the lines at the end of the bus
New implementation of RTC circuit, increasing shelf-life to approximately a decade
PPS signal added to the GPS1. On Skynode, it is brought out on J4-17. Pixhawk Adapter Board A000036-06 changed accordingly: GPS connector size increased to 11 positions, PPS is on pin 6
Added latching circuit to keep the ethernet switch powered in case of a power failure on the SOM
RC input now supports PPM
Current limit for SOM was tightened to 1.5A
Added ESD protection on USB-C
USB-C handshaking with MacBooks works more reliably now
Revision of base board was incremented; now the EEPROM will contain the board rev
Removed the unconnected CS2 and DRDy2 from SPI connector on FC IO Secondary breakout board, shrunk SPI connector to 9 pin
Minor ESD hardening measures
Minor internal component replacements to achieve extended temperature range and adapt to component availability
Compatibility
The evaluation kit will be updated in sync, a new GPS module with PPS support will be included as well as the according breakout boards.
A000036-05 (Pixhawk Adapter Board) and A000037-03 (Pixhawk Payload Bus breakout board) can be used with the Skynode revision 11, but the CAN bus needs to be terminated externally.
A000036-06 (Pixhawk Adapter Board) and A000037-04 (Pixhawk Payload Bus breakout board) should not be used with the Skynode revision 09.
To use the Freefly RTK GPS with A000036-06 (Pixhawk Adapter Board), a custom cable will need to be made to fit the new pinout of the GPS1 connector.
Timing
Skynode revision 11 starts shipping in January 2022.
Software
This revision is only compatible with AuterionOS 2.4.2 and later
