Grove Variable Color LED V1.1 and V1.0
Model: 101020472, 104020001
The Grove Variable Color LED V1.1 or Grove Variable Color LED V1.0 is an RGB LED module in Grove form factor, the LED size is 8mm. It operates at 5V DC only. The three resistances RED, GREEN and BLUE on the module control the R, G and B channels respectively. By adjusting the three adjustable resistances, it can turn out the variable color. With V1.1 a logic IC was add to avoid power supply issues.

Utilization
Requirements
This shield can only be used with a development board or shield that provides
a configuration for Grove System connectors with Grove Digital Layout
and defines the device tree phandle grove_gpios and grove_pwms as an
Laced Grove Signal Interface.
Programming
Set -DSHIELD=grove_led_dX or -DSHIELD=grove_pwm_led_dX when you invoke
west build, wherein X corresponds to the ordinal number of Grove signal
from the Laced Grove Signal Interface. For example:
Using west:
west build -b mimxrt1060_evkb -p auto -d build/helloshell-seeed_grove_base_v2-grove_led_d6 bridle/samples/helloshell -- -DSHIELD="seeed_grove_base_v2 grove_led_d6"
west flash -d build/helloshell-seeed_grove_base_v2-grove_led_d6
Using CMake and ninja:
# Use cmake to configure a Ninja-based buildsystem:
cmake -Bbuild/helloshell-seeed_grove_base_v2-grove_led_d6 -GNinja -DBOARD=mimxrt1060_evkb -DSHIELD="seeed_grove_base_v2 grove_led_d6" bridle/samples/helloshell
# Now run ninja on the generated build system:
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_led_d6
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_led_d6 flash
Using west:
west build -b mimxrt1060_evkb -p auto -d build/helloshell-seeed_grove_base_v2-grove_pwm_led_d6 bridle/samples/helloshell -- -DSHIELD="seeed_grove_base_v2 grove_pwm_led_d6"
west flash -d build/helloshell-seeed_grove_base_v2-grove_pwm_led_d6
Using CMake and ninja:
# Use cmake to configure a Ninja-based buildsystem:
cmake -Bbuild/helloshell-seeed_grove_base_v2-grove_pwm_led_d6 -GNinja -DBOARD=mimxrt1060_evkb -DSHIELD="seeed_grove_base_v2 grove_pwm_led_d6" bridle/samples/helloshell
# Now run ninja on the generated build system:
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_pwm_led_d6
ninja -Cbuild/helloshell-seeed_grove_base_v2-grove_pwm_led_d6 flash
