Hi German, do you sell the equipped and tested boards for private use?
I don't sell, but is very easy to make it
Did you create this PCB with Eagle? If so, would it be possible to get the file?
Sprint-Layout 6.0I will upload files and post link here

I see that you used a zener diode between the rx and the gnd of the arduino. Is this needed?In the pictures above (photo's, layout's and schematics), this diode is not always present...
Looks like the zener is there to protect the RX output to the Arduino so that it never can go over 5V. Could be just preventative or it could be a decent measure against ESD being able to take out the Arduino.
Stabilize 5v signals to Arduino
Hi! What do you mean by "For digital pins ( 0 -> 5V) not for Serials (5 -> 0V)"? Not to use the Rx/Tx-pins on the Arduino and use SoftwareSerial (or something similar)?
Seatalk use 5-0v (bit 0-1) signal not 0-5v (bit 0-1)
Hi German, I found your projects very interesting concerning Seatalk stuffs, I have an ST4000+ and at the moment I want to use OpenCPN soft. to control my ST4000+. looking at the circuit supply here of Thomas Knauf you did added on R6, what is the reason for that? thanks and have a nice day.
TTL signal to Arduino must be 5V 6k8 & 4k7 voltage divider for 12V from Seatalk powerin the middle of two resistors = 4.90V
Yo pondría un zener de 5v en paralelo con R6
Ya está incluido en la placa 5v1
Hola, ¿hay alguna posibilidad de comprarte una placa equipada?
No, pero te puedo enviar los ficheros en formato Gerber y te las hacen en China por unos 10$ (5 placas), y los componentes son muy sencillos y fáciles de montar.
Gracias, puedes escribirme a firstname.lastname@example.org
Enviado por email los ficheros Gerber de las dos PCBs
Añadido al link de descarga los ficheros Gerber.rar para el que quiera encargar las PCBs a China:https://cart.jlcpcb.com/quote?orderType=1&stencilWidth=100&stencilLength=100&stencilCounts=5&stencilLayer=2&stencilPly=1.6&steelmeshSellingPriceRecordNum=A8256537-5522-491C-965C-646F5842AEC9&purchaseNumber=o cualquier otro.
I ordered 5 PCB, only need one ... I'll have four available if anyone needs.
Do you still have those, are they with 7805?
Hi, a quit one, on your Seatalk Bidirectional with 7805, for the moment I have a buch resistors on hand but they all 1/4 watts, would it need to be 1/2 watts.
1/4w is valid
In the download file are the Gerber files to make the PCB (JLCPCB or other)https://cart.jlcpcb.com/quote?orderType=1&stencilWidth=100&stencilLength=100&stencilCounts=5&stencilLayer=2&stencilPly=1.6&steelmeshSellingPriceRecordNum=A8256537-5522-491C-95842C-646pur
Hi, I know I could go JLCPCB, I just want to know what file I have to give them in order to make the order. Do I have to send them the whole GERBER.rar file as is to them or only 1 of them of the 5 files that is in the GERBER.rar file. I just want to understand how it work, thanks for patience.Gilles
Me again. I think I know now what is involve to place an order to JLCPCB as I made some reading what is involve to get there. So that is the whole GERBER.rar file.Any way thanks for patience.Gilles
Hi Berr, just came accross your blog, I'm trying to connect my st2000 tiller with arduino Uno. Which one of your project is suitable for starting working on it? I read about 9bit do I need to use a specific library and IDE?Tanks for any information
https://berreizeta.blogspot.com/2017/02/seatalk-simulator-arduino.htmlAny of the projects on this blog that use arduino, like this one above.Yes, for all communications with Arduino you need the 9bit library (included in downloads)
thanks a lot for answering me, is there a way to check 9bit is working fine? So in case of not evidences I can focus the attention of the pcb board. thanks again
All seatalk- arduino projects works fine with 9bits library
Super. good to know that.
