Educational board for strain gauges, Wheatstone bridges and op-amps

I designed this board for learning and educational purposes. It is a reverse-engineered copy of a popular PCB for strain gauges from a webshop. I thought it would be cool to replicate the circuit with through-hole components for easier reproducibility and with a bit larger separation of the different sections, so the circuit could be used for educational purposes. The production went quickly as usual and I got the products shipped fast. The quality of the PCBs is great. The holes are drilled properly, the traces are etched nicely (notice the teardrops!) and the silkscreen is also flawless. Great work from PCBWay, as usual. Thank you!
