ATMEGA8 developers kit + usbasp programmer combo
This combo includes our popular ATMEGA8 development kit and a USBASP programmer.
28 Pin AVR Full Size Development Board
IC Socket 28 pin 7.62mm (0.3")
ATMEL ATMEGA8-16PU 8 Bit 8K AVR Microcontroller
IDC Male connector (shrouded header), 10 pin, right angle leads
Resistor - Metal Film 1/4W - 10K
Micro Tactile momentary SPST switch
16MHz Crystal in HC/49S through hole package
Capacitor - Resin Dipped Ceramic Axial 100V 22pF
Capacitor - Resin Dipped Ceramic 50V 100nF
This kit is based on the 28 pin AVR board that Jonathan Oxer Reviewed. Jonathan is the author of Practical Arduino, which is a very good book.
The current bord being sold is version 1.4 which includes the following improvements over the one that Johnathan reviewed:
* Updated external crystal block in ground plane for better isolation
* Updated AVCC block with room for bigger inductors
* 300mil (7.63mm) gap between I/O port and 5 hole protostrips. A resistor, piece of wire, dip switch
or other component of choice may be used to bridge this gap
* Power rails are double sided to allow for greater current
* Better pin layout for reset switch
* Clearer labelling of I/O lines
* Addition of power supply section
* ISP-6 interface is now 2x3 pin instead of 1x6 pin
* Addition of IDC/Double row header section
* Clearer labelling of power busses
60 mil for power busses and prototyping section
This board is based on a standard breadboard with a few improvements.
* Power busses are pre routed on the board
* Power busses go from edge to edge and do not have any gaps
* Power busses are available in gap were Dil components usually sit. This provides more flexibility for component placement and allows for more options for connecting power to components.
Screen printing on the board top clearly shows power busses and connection points.
Connection strips on top and bottom edges
All Protostack prototyping boards have sets of 3 connected pads on the top and bottom edges. These are used to interface each board with the adjoining board above/below or to interace the board with an external system.
Standard protostack form factor and mounting holes
Protostack full size boards have a standard size and 6 mounting holes on the top and bottom edges. This allow the board to be stacked with other full or half size boards using hexagonal spacers.
This is a premium lead free treatment which protects the copper tracks from oxidation and make it easier to solder.
On all board areas except the solder pads a polymer based mask is applied. This is a common practise on commercial PCBs but is less common on prototyping boards. The solder resist prevents bridging between tracks and make soldering easier.
We use quality FR4 fibreglass board material unlike the paper based phenolic material that is found in many prototyping boards. Fibreglass reinforced substrates have a much higher strength that paper reinforced boards and are more resistant to cracking or breaking.
