i2c Question #99

Closed randyb128 closed 1 month ago

randyb128 commented 2 months ago

I want to connect an i2c DS3231 real time clock chip to I/O lines 21 and 22 of a LilyGO-T-A76XX device. My question is, your schematic doesn't show any resistors on 21 or 22 but physically it looks like there might be a resistor pack connected on the back of the board to those pins. (see picture) It looks like it could be a pull down resistor. If so, what is the value? 48fb49ed-7531-474b-81dc-f212cd3a59ac

image Resistors you can add externally, most modules come with their own resistors
