### Known Issues
#### Version 1
- Used CAN tx/rx instead of hardware UART
- Connections from FTDI to RS485 transceiver wrong, need to short DE / RE pins together, then this connection goes to FTDI enable. PWREN for the RS485 converted is wrong naming and doesn’t reflect its purpose. No connection to PWREN on 4232 needed...
- Missing 3v3 rail connection to VBAT pin on Teensy. Will program without it, but will not boot without it.
- For R46 vs R47 selection, only R47 is needed.
- No invert needed for S.BUS connection (bridge pins)
