M2135-1/M2030-1 MOTE DATASHEET DUST NETWORKS™ 7
CONFIDENTIAL
5.0 Pinout
The M2135-1 and M2030-1 have two 11-pin Samtec MTMM-111-04-S-S-175-3 (or equivalent) connectors on the bottom side
for handling all of the I/O. The third pin in each of the connectors is not populated, and serves as a key for alignment. The
connectors are mounted on opposite edges of the long axis of the mote.
The M2135-1 and M2030-1 provide a bidirectional flow-controlled serial interface (serial protocol is specified in 7.3.1).
The RST input pin is internally pulled up, and is optional. When driven active low, the mote is hardware reset until the signal
is deasserted. Refer to section
6.1 for timing requirements on the RST pin. Note that the mote may also be reset using the mote
serial command (see section 7.3.3.8).
The TIME input pin is optional, and must either be driven or pulled up with a 5.1 MΩ resistor. Unless noted otherwise, all
signals are active low.
