motor controller data extension
This extension cable is for serial data connection of the autopilot allowing the autopilot computer and controller to be mounted further apart. It includes the waterproof 4 pin connectors on each end compatible with autopilot computers and motor controllers on this store.

Depending on the configuration, it may be desirable to mount the motor controller further from the autopilot computer. I do not use an extension on my boat so please consider if it is actually needed/useful for you. For example, if there is already power near the drive motor it can make sense, especially if using rudder feedback as these runs would also e much shorter.

isolated USB to NMEA RS422 Adaptor
Compatible with marine equipment NMEA
  • ADM2484 provides galvanic isolation, short circuit protection, and electrostatic discharge circuitry
  • bi-directional isolated serial data transfer- baud rate 300 to 1,000,000- mini usb connector
  • works with RS422 and RS232.
  • ch340 usb serial converter supports linux/windows/mac
  • 1500 volt isolation prevents ground loops and equipment damage
  • protected from transients by TVS diode
  • low current consumption
  • tested with standard horizon GX2100 receiving AIS messages into OpenCPN
  • tested with NMEA depth sounder

rs422 connections A and B are inputs, Y and Z are outputs
rs232 use A NMEA common, B NMEA IN (+), Y NMEA common, Z NMEA OUT(+)

leds indicate data is being sent and or received. If led stays lit without data, there is a wiring problem. Ensure both A and B for receiving and/or Z and Y for transmitting are secured. From a serial console ensure baud is correct. NMEA uses 4800 8N1, or 38400 8N1 for high speed such as AIS. If data is received but garbage, try reversing A/B or Y/Z.  Recognized on linux as /dev/ttyUSB* Other OS may require drivers

433mhz RF remote
Additional 433mhz RF remote, battery included.
One remote is included with the tinypilot and pypilot hat, but you may want additional remotes.
Each remote sends unique codes. They must be programmed to pypilot by visiting: http://192.168.14.1:33333
Or alternately under openplotter eg: http://localhost:33333, depending on how he network is configured.

IR remote control

Infrared Remote control.


This is a cheap remote control and requires the remote to see the IR sensor on tinypilot computer or pypilot hat. Sometimes it works from reflections as well. It maybe useful as a backup remote and is easier than wiring momentary switches.
For a better remote, consider the 433mhz wireless remote control.
