New circuit diagram on June 29 [Copy link]

The changes in the new circuit diagram are: two buttons are added to replace the coding switch, because the coding switch is more difficult to buy. The original circuit that uses triodes for 3.3V and 5V level conversion is replaced with a dedicated level conversion chip, so that there is no inversion.

I don't seem to see the acquisition board part. I checked it all over. Is it because my eyesight is not good?

1. SCL and SDA are misplaced; 2. Pin 7 should be grounded.
