This is nanovolt-accurate interconnects and hardware group-buy call.

xDevs.com needs some copper hardware for new upcoming project, so to benefit the community we decided to make a public group buy order to a manufacturer.
This is general call for custom hardware, for low-thermal EMF connection hardware, especially useful for DC nanovolt/microvolt level signal measurement/sourcing projects.

Order requests are NOT accepted anymore, but we might do this in future again.

Deadline for all order requests : August 2, 2019 All orders are finalized and currently in manufacturing, as we are short on few items.
