## Detailed Description

Minimalistic Board with ATtiny84 / AT86RF230 by DL8DTL.

The wiring of the radio and the ATmega is shown below:

         AVR       RF230
         ---       -----
         PA5  -->  MOSI
         PA6  <--  MISO
         PA4  -->  SCK
         PA7  -->  SS
         PB0  -->  RSTN
         PB1  -->  SLPTR
         PB2  <--  IRQ (INT0)
                   MCLK (NC)
         PB7  -->  (reset)

         PA2   <--  KEY
