 * @brief Atmel Radio Development Kit, AT86RF230 Radio Adapter with Atmega1281.
 *
 *
 * This board wiring fits the Atmel radio development kit and/ or Dresden Elektronil RCBxxx family.
 * hardware and compatibles.
 *
 * The wiring of the radio and the ATmega is shown below:
 *
<pre>
          AVR      AT86RF230
          ---      ---------
          PB4  -->  SLPTR
    XTAL1/PD6  <--  CLKM
          PD4  <--  IRQ (ICP1)
          PB5  -->  RSTN
          PB0  -->  /SEL
          PB2  -->  MOSI
          PB3  <--  MISO
          PB1  -->  SCK

    KEY: PE5
    LEDS PE2:PE4

Fuses/Locks:
     LF: 0xe2 - 8MHz internal RC Osc.
     HF: 0x11 - without boot loader
     HF: 0x10 - with boot loader
     EF: 0xff
     LOCK: 0xef - protection of boot section

Bootloader:
    Start at byte=0x1e000, address=0xf000, size = 4096 instructions/ 8192 bytes

@par Build Options

 All rdk2xx derivates will also work with a combination
 of STK500 + STK501 with mega1281 + Radio Extender Board
 on Expand1 connector.

 For UART connect PD2/PD3 on 10 pin header with RXD/TXD
 at STK501.

  - rdk230b : RCB230 V3.2 / RCB230 V3.3.1 (AT86RF230B)
  - rdk231  : RCB231 V4.0.2 / RCB231ED V4.1.1
  - rdk212  : RCB212SMA V5.3.2
  - rdk232  : Radio Extender Board + STK500 + STK501
