Crumb8

Updated: Jan 20, 2005

Description

Crumb8 is a ready to use "rapid prototyping module" for the ATmega8 on just 18x36mm² (DIP28).

The following components are integrated:

• the ATmega8 in TQFP32 package
  
• two single-row 14 pin headers with the ATmega8 signals (except XTAL) on DIP28 form factor
  
• one serial port (incl. RS232 transceiver and 5 pin header)
  
• reset circuitry
  
• 14.7456MHz quartz (XTAL)
  
• 6 pin ISP header
  
• reset jumper
  
• status LED
  

STK500 Bootloader

Crumb8 is being shipped with a preinstalled STK500 compatible bootloader (stk500boot), which allows programming of the ATmega8 in system through the serial port, i.e. without a dedicated ISP adapter! Almost any popular programming software like AVR-Studio, avrdude or uisp can be used. The "Connector Kit" (as mentioned above) contains a simple Sub-D-9pin to 5pin adapter, which allows direct connection of a standard PC serial cable to Crumb8.

In contrast to the Crumb128 bootloader, the Crumb8 bootloader does not provide additional monitor functions, due to less program memory on the ATmega8!
