3 MPR400/MPR410/MPR420 (MICA2)
3.1 Product Summary
The MICA2 Motes come in three models according to their RF frequency band: the MPR400
(915 MHz), MPR410 (433 MHz), and MPR420 (315 MHz). The Motes use the Chipcon
CC1000, FSK modulated radio. All models utilize a powerful Atmega128L micro-controller and
a frequency tunable radio with extended range. The MPR4x0 and MPR5x0 radios are compatible
and can communicate with each other. (The x = 0, 1, or 2 depending on the model / frequency
band.)
