Payment via paypal as friends/family/gift.
$25 each plus shipping. I can ship USPS priority mail (tracked and insured) or USPS first class mail (no ins, tracking, but lower cost) to the US, Canada, and Mexico. Will consider shipping to Europe, but, it will have to be a first class envelope mailer, as USPS priority shipping to Europe costs more than the PCB itself. PCBs are blue. Designed by Edu Arana. I built one myself 2 days ago, and it works flawlessly.
