Grove Connector
The specification of the grove connector is on the assumption that Grove modules are to be connectable;
GROVE1 to GROVE3 are for connection through I2C. If a connector is mounted, however, connection to all
Grove modules (through I2C) is not guaranteed. Use this connector after having confirmed the specifications
of this product and Grove modules (through I2C) you intend to use.
Figure 5-3 and Table 5-7 to Table 5-9 show the pin assignments of the Grove connector.
