Hi,

I am building my first pcb, the basic design principle is to amplify the current produced by photodiodes(BPW34) which will be connected externally to the input pins of the pcb. Whereas the outputs will be connected to an esp32. I would be grateful if somebody could provide feedback on the circuit/ overall pcb.
