Mechanical description
The RF231USB-RD is manufactured using a four-layer printed circuit board. The components mounted on the top side
are: ATSAM3S4BA microcontroller and low-power radio transceiver AT86RF231 (including their crystal oscillators),
2.45GHz antenna and the SMD-mounted USB type A plug. The bottom side of the board is equipped with the following
components and connectors (among other): 2GB additional flash chip, 10-pin connector, three status LEDs, ERASE
and VCC pins, voltage regulator for power supply.
Dimensions
Due to size constraints, components are placed on the top side as well as on the bottom side of the board. The USB
plug is mounted on edge of the board. Board width and height were chosen so that multiple USB sticks will fit beside
each other in standard USB hubs. Board length is determined by size of the ground plane which is approximately λ\2 for
2.4GHz band.
