#### Grove Sensors
* **Grove LCD RGB Backlit** (JHD1313M1) requires 5V and should be used with an
external power supply connected to the board to function properly. Although
some high powered USB ports might be enough, in most cases you will encounter
dropped characters, washed out text and/or failed I2C writes while using USB
power alone.
* **Grove I2C Touch Sensor** (MPR121) v1.3 is incompatible with the Intel
Edison using the Arduino board, but will work with the Mini-breakout if
supplied with at least 4V. Revision v1.2 works well on all Intel boards.

Edison with the Arduino board.
* **Grove I2C Motor Driver** is not compatible with the Intel Galileo due to
the inability to change the I2C bus speed to 100 KHz.
* **Grove Digital Light Sensor** (TSL2561) may have an unstable connection on
the Intel Edison using the Arduino breakout that results in missed I2C reads.
This is usually applicable when the I2C lines are pulled-up to 5V.
* **Grove CO2 Sensor** will return zeroed data and is unusable on the Intel
Galileo.
* **Grove BLE** (HM-11) does not return data on the Intel Galileo board due to
