Contact Information For PJRC

We are located in Sherwood, just south of Portland, Oregon, USA. This page lists a variety of ways you may contact us.

Email For Paul Stoffregen

Paul's email is Technical questions should go to Paul. All sorts of technical questions are ok, but please try to be specific and include enough detail about your setup. If you have a PJRC product, be sure to specify exaclty which one and what revision it is. If you've built your own hardware, Paul will have an easier time and be able to help much more if you include technical information such as a schematic and source code. Paul also edits most of the HTML and CGI that runs the website, so if some part of the site isn't working or has an error, it's best to email Paul about it.

Email For Robin Coon

Robin's email is Robin handles all financial and most administrative tasks behind PJRC, so questions and concerns about shipping and billing are best sent to Robin. If you need to make some special billing arrangements, like a bank-to-bank wire transfer, you definately need to contact Robin.

Of course, you may email either of us to chat.

Telephone and Fax

Our Fax machine is on 24 hours/day, but if you call us, please remember that we are on the West coast in the USA (Pacific Time Zone). Also, please keep in mind that we are not able to answer calls during many hours of the week. If you leave a message, we will attempt to get back to you. In general, email is a more reliable way to contact us.

Voice(503) 625-9328
Fax(503) 625-9840

Many people are understandably unconfortable with entering their credit card number to a (SSL encrypted) web page. The fax line is an excellent alternative. You can enter 0000-0000-0000-0000 as your card number, press the button to enter the order, and then print either the final confirmation or the automatic confirmation email. Just write the card number on the printout and fax it to us.
