hello, i have copy your board and made its pcb and i assemble the board but doesn't work. i check all the voltages and all of them is same as pcb design. i have doubt on program and libraries versions.can you send me the library and board manager version ?

Hello @Mic-Tsai,

Nice work.

I have a question regarding your electrodes - what are they made of? SST 316? And, what is the method of attachment?
Are the backs of the electrodes bare metal or is there an insulator on the back?

Your analog ground circuit is interesting - are there any issues with static electricity doing that?

Thanks in advance,
whf
