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
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!
Retail price is 19,95 Euro (incl. VAT, net price is 16,20 Euro for companies or non-EU customers!!!). Accessories available at www.chip45.com.
