11 SENSOR BOARDS & EXPANSION CONNECTORS
Crossbow supplies a variety of sensor and data acquisition boards for the Motes. This Chapter
describes the connectors and the functions of the pins for the MICAz, MICA2, MICA, and
MICA2DOT.
Information for customized sensor board design is available on the Crossbow web site.

11.2 MICAz and MICA2 Expansion Connector
Connection to the MICAz and MICA2 Motes is by a 51-pin connector (see Figure 11-1 below).
Figure 11-1. Hirose DF-51P-1V(54)Digi-Key part no. H2175-NDon left is used on the
MICAz, MICA2, and MICA Motes boards. The Hirose DF9-51S-1V(54)Digi-Key part no.
H2163-NDon right is the corresponding connector used on the MIB Interface Boards and
Stargate Gateways.
The expansion connector provides a user interface for sensor boards and base stations. The
connector includes interfaces for power and ground, power control of peripheral sensors, ADC
inputs for reading sensor outputs, UART interfaces, and I2C interface, general-purpose digital
IO, and others.
