AVR200: Low cost kit or small system controller       
Go to AVR200

The $A99 AVR200 kit, ($A185 built and tested) is a low cost ATmega32 based board for industrial/educational/hobby applications. Protected I/O is provided from all ports to screw terminals and it also provides a RTC, SPI, RS232, buffered I2C bus (and RS485 option).

AVR256: High-end CPU board with 4 serial & 32 I/O      
Go to AVR256

The ATmega2560 is a standard ATmega core CPU with 8K RAM, 256K FLASH, 4K of EEPROM  The board supports a GPS, an X-Port Ethernet interface, an 802.11 or other radio, and a SD/MMC memory card. Interfaces include I2C, RS232 and SPI. These support on-board 8Mbyte DataFlash memory for logging.

AVR570 CPU piggy-back modules       Go to AVR570 family

This 47mm square module has an ATmega128 as standard, but can have an ATCAN128 (CAN bus) or the new ATmega2561 CPUs (with 8K instead of 4K RAM). This allows a surface mounted CPU to be used in a user-built, through-hole-only PCB. As well as the CPU, a DS1305 Real Time Clock with back-up battery is an option.

AVR573 base for AVR570 modules       Go to AVR570 family

This mounts 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 drives an LCD display and keyboard. 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.

AVR585 CPU board with three com ports, Xilinx FPGA      
Go to AVR585

This board uses an ATmega128 CPU, and with a dual UART (ST16C2550CQ48), offers a total of three RS232 serial ports, an RS485 port, an iButton 1-wire port, and an LCD / keyboard / program download port, as well as a large Xilinx SpartanXL gate array and 16 general purpose I/O lines.

AVR595 new “Little Ozzie Logger” small ATmega2561 board   
Go to AVR595

This little board is designed as a data gathering device, saving the data in its internal 8 Mbyte of DataFlash memory. This is buffered with 32Kbyte of Ramtron FRAM. An interface to the V-Drive USB memory stick is also provided. It has a highly accurate temperature-compensated Dallas RTC, which can control start-up and logging cycles.

It uses an ATmega2561 CPU and has eight, 10-bit analog or switch/voltage digital inputs and twelve other I/O pins which can have 8 power FETs as outputs or protected inputs. An additional "delta-sigma" ADC provides 4 channels of low level (thermocouple-style) analog input.

It has a Dallas/Maxim 1-Wire, and either two RS232 or one RS232 and one RS485 serial port. It can also provide CMOS level communications into a radio modem. It also has an LCD interface. (A 4 x 20 text LCD can mount directly on the back.), can scan a 4 x 4 keyboard and read a DIP switch for setup or address information.

AVR-ISP MkII In-system programmer. (Available from JED for $75 ex)

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. (JED has a 10-pin adaptor available.)

A full data sheet is available for download at: AVR-ISP mkII user guide under "Documents".

(Note: This is not an Australian made product.)

The second group use the Wilke Technology BASIC Tiger

Go to Tiger family

The Wilke Tiger is a microprocessor module family all running complied Tiger Multi-tasking BASIC. (JED uses these Tigers in quantity to power the T460 Audio-Visual Controller.)
