AVR570 ATmega128/CAN/ATmega2561 CPU module, from $A60 + GST
This 47mm square module has an ATmega128 surface
mounted CPU, a reset chip, a CPU crystal, an optional DS1305 Real Time Clock
with back-up battery and four rows of pins to connect to either your custom
designed base board, or our AVR572 proto board or the AVR573 board below.
In full production, at a VERY good price.
(Note: we normally ship with a
3.6864 Mhz crystal, but other values, eg 16.000 Mhz are available on request.)
The AVR570 is now available with options of ATCAN128 (CAN bus) or the new ATmega2561 CPUs (with 8K instead of 4K RAM).

AVR573 base board for AVR570: Data sheet available
This 160mm by 100 mm board is an all-through-hole base for the AVR570 module, and has 8 analog in, 1-wire in, 12 digital in to the CPU, 4 outs from the CPU to power FETs and 8 other FET outputs from an addressable latch.
It can drive an LCD display and scan a small keyboard
in a way compatible with BASCOM or CodeVision compilers.
It can have a GPS module or an expansion board added
to an extension area, and has two RS232 or one RS232 and one RS485 port.

AVR572 prototype base board for AVR570, board $A40, kit $A60 +GST
This is a base for users making one-off application board, or prototyping
a system which will use the AVR570 module in production, or even for TAFE
student or hobby projects.
Across the top are spaces and pads for six 5-way
Phoenix 0.15" spacing screw socket connectors.
Across the bottom are double-row 0.1" spaced pads
for ribbon cable connectors with solder pads for each pin for wiring just
above them.
Vcc and ground tracks cover the board, and there
are hundreds of dual-pads for ICs or discrete components.
At the left-hand end is wiring for a 5 volt linear
voltage regulator and a MAX208E 4 TX, 4 RX chip for the two serial channels.
(Available as just a PCB or as a low cost kit with
essential components like the voltage regulator and heat sink, the MAX208E
RS232 chip and socket strips for the 64 AVR570 pins.)
AVR-ISP mkII, In-System Programmer for all AVR microprocessors, in stock, $A75 + GST
The AVR In-System Programmer is used for field upgrades of existing products
using the Atmel AVR Architecture. The In-System Programmer is based on the
STK500 Hardware and Software. It supports all in-System Programmable AVR
devices. It is supported by all AVR compilers (CodeVision, Imagecraft C,
BASCOM, AVR Studio). Because it runs from the PC USB port, it avoids problems
with printer port modes (ECC, Std, etc) and operates under all PC operating
systems with USB support.
It is supplied with a 6-pin programming cable, so is suitable for all
the recent JED boards and modules shown above.
(Because a 10-pin cable header is not provided, there is a problem in interfacing to older boards with the 10 pin ISP header, or boards like the JED 585, which has a 14-pin connector, formed by adding 4 extra pins to the Atmel 10-pin standard. We are quite unhappy that Atmel has dropped the 10-pin support without any warning, and will soon make available an adapter board to convert the 6-pin cable to the 10 and 14 pin standards. Contact JED for availability.
A full data sheet is available for download at: AVR-ISP mkII user guide
Note: The older serial RS232 port AVR-ISP is no longer available. It
has been suddenly deleted, without warning by Atmel.
AVR assistance from JED
If you are interested in using AVR processors for any project, small or large ... email or call Ed Schoell at eschoel@jedmicro.com.au with your comments or questions. (03 9762 3588)
JED offers a design service for boards
or systems based on AVR, Xilinx gate arrays and a range of other electronic
hardware and software projects. We have a group of standard circuit and
gate array design modules, with matching software drivers developed during
our time creating the Little Blue Computer and friends and we have designed
a number of custom systems based on AVR using this experience.
