The original USP mote board is shown below.
This board features the MC13213 SoC by Freescale. There are a number of these devices available for research in Brazil, but the layout has been modified to separate the board into two sections, a motherboard, and a daughter-card. This separate board is available publicly on the OpenWSN source tree. The same OpenWSN code will tun on both platforms. If a #define ELDORADO_BOARD is specified in the code, the pintouts for the old board will be used. If not, the pinouts for the new daugthercard will be used.
The motherboard is shown below.
The layout and schmatics for the motherboard are given below. As it stands, either a daughter-card on the MC13213 can be used, or a separate daughter card based on an ARM7 uC can be used.
The daughter card, mother board combo, based on the MC13213 is shown below.
While the ARM7 based daughter card has not yet been built, the schematics are available.
A more powerful motherboard has also been designed to be interfaced as a handheld in the future.
