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
     PA0:1 -->  LED
     PA3   <-- Thermo Sensor

     lfuse: 0x62 (8MHz in Osc., no clock divider)
     lfuse: 0xe2 (8MHz in Osc., w/ clock divider)
     hfuse: 0xDF for ISP Mode, 0x9F for debug wire
     efuse: 0xFF
