Arduino Potentiostat

I am an electrochemist and I am going to make a small project related to amperometric sensors. For this reason, I need a simple Arduino-based controller (potentiostat). I found the scheme under a free license and at first I was planning to make a pcb-board on my own, but then I accidentally found a link to the PCB Way and decided to order it here, using the discount for new customers. As a result, I only paid for the delivery, and received the boards of excellent quality. My order is extremely simple, but nevertheless - they did not refuse to fulfill it. I'm really impressed! It remains only to solder the parts and test it. Undoubtedly, in my future projects I will turn to PCB Way for help in order to produce high-quality prototypes. Many thanks! I will recommend you to all my friends!
