GROVE connectors
The UDOO Bolt board offers the possibility of managing Seeed Technology Grove family of sensors through the Arduino platform by using three dedicated
connectors, directly managed by the ATmega ATmega32u4 controller.
All three connectors are type TKP p/n P20Y1L-04SMT or equivalent, with the pinout shown in the
tables on the left.
Mating connector: TKP receptacle p/n H20Y1-04 with TKP DHT-1S(LF) female crimp terminals.
The signals available on these three connectors are the same available on the Arduino interface
connector CN24.
Please notice that these connectors seems to be mirrored with respect to GROVE standard connectors. Actually, the pinout shown in these tables is referred to the
real pin position #1 engraved on the connector. Cables designed for GROVE sensors will fit into these connectors without needing any change.
