Grove - 16x2 LCD - Seeed Wiki

6/20
The rst version of Grove - 16 x 2 LCD series does not have a built-in
pull-up resistor, nor does it provide a pad to solder the optional pull-
up resistor. We have redesigned the module, and the new version
has built-in pull-up resistors.
If you have an older version on your hand, you can solder a 10k
Ω
DIP resistor yourself on the back pad of the Grove connector.
Please follow the picture below, solder a 10k
Ω
DIP resistor between
VCC
and
SCL
pins and a 10k
Ω
DIP resistor between
VCC
and
SDA
pins.
