Line Driver Module PCBs


Recommended Posts

Hi midiboxers,

I need a pair of line driver modules. I am thinking of starting a production run of the PCBs at OSH Park.

Anyone interested to join? Maybe I could also provide the parts as kit.

Currently I don't have any information about prices / shipping costs yet, so just show your interest for further planning here.


PCBs arrived at my place and few pairs are (still) available for you!

(Two pairs shown.)

Price is 13,80EUR for each pair (One TX and one RX PCB).
Shipping worldwide 3,45EUR.

To definitely buy, please send me a PM which includes:

  • Full name & adress for shipping the PCBs
  • Amount of TX/RX pairs you want to buy
  • e-Mail Address for sending paypal invoice

If you have trouble getting the parts, please let me know, maybe I can send you some of the parts, too.

1st price estimation:


One pair of PCBs will be between 14 - 16 EUR (depending on customs, taxes ...)

Shipping to anywhere in the world 3.45 EUR (even more pairs together, as long as weight less then 500g)


So you'll get one pair definitely for less then 20 EUR.


If you want, you can refine your postings above about quantities (Edit). I will start a production run of 20 pairs. And then 1st come 1st serve :-)

You buy one for him? Shall I ship it then to him or three pairs to you?


Since the boards are out of fab today and on the way to myself, I soon know how much the exact price will be. I will announce it here and then you can place your binding orders.

Hi all

Some update/info

I recently populated a pair too. Work fine :rolleyes:

I can also say it make the data stronger than the direct core connection.

I'm able to connect the first Dio and Aio with 1m ribbon from RX card, which is not possible if I connect them directly to the core :happy:

One thing to be careful with is the sub25 cable, I have a important supply voltage drop with 5m which make the RX and following SR acting bad.

My design take care of this with separate supply wire, so it's ok, just be careful with this if you note strange behaviour.

Any pairs still left?  If so, I'll take one. 

Yes, I have one pair left. Send me a personal message with your address for shipping to get this final one ;-)

You can pay per Paypal oder bank transfer, depending on your country. Eventually send me your e-mail address for Paypal. It's 17,50 EUR incl. shipping.
