This programmer is OS independent (stk500 V2 protocol) and can flash any Atmel avr microcontroller with In-System Programming capabilities. It can flash microcontrollers from 3V to 5V.

To the programmer software (avrdude, avrstudio, ...) this hardware looks just like a stk500v2 on a virtual com-port.

This kit includes:

A high quality printed circuit board (double sided,through-hole connections, gold plated). The FTDI SMD chip is already soldered to the board.
Bootable CD (like knoppix Linux), tuxgraphics Linux AVR programming CD
Documentation: pinout description of the components, circuit diagram, resistor color codes, drawing and photo of the PCB with all the components
Capacitors: 3x 100nF, 1x 10uF, 2x 18pF

The CD includes the avr-gcc tool chain. The CD is independent of the operating system and software on your PC. It is a bootable CD with a graphical desktop and the complete C-Language programming environment (avr-gcc and avr-libc-1.4.3).
The CD includes (besides the knoppix booting capability):

AVRstudio 4 for windows; to use the AvrUsb500 under windows
Windows drivers for the USB interface of the AvrUsb500v2
avrdude programmer pre-compiled for MacOSX (on PowerPC and Intel)

IDE CD-rom.
Pentium CPU (i586) with 400MHz or better, the computer should not be older than 3 years.
USB interface
Minimum 256Mb of Ram.
Note: the CD will not boot on a Mac.

Main features of the avrusb500v2 programmer:

Fast programmer with USB interface
Recongnizes when the connector to the target is inserted with incorrect polarity
Works with almost any system (Windows, Linux, Mac, ...)
Provides a 1MHz emergency clock signal to recover from incorrect fuse settings.
Easy to build. Standard components. The SMD chip is already soldered to the board.

price: 20.00 Euro [convert_currency]

Note: You need also an Atmega8 microcontroller to build the AvrUsb500v2 (the Atmega8 is not included in this kit).

Check also our simple generic development board and the tuxgraphics to atmel 10-pin or 6-pin programmer adapter further down.

price: 0.90 Euro [convert_currency]

AVR programmer USB, all SMD, stk500 V2 compatible, ready for use.

AvrUsb500 as mini SMD version. The components are sealed in transparent plastic. It is very small but still robust and made for day to day use. This is high-tech and quality!

AvrUsb500 SMD is probably the smallest and most powerful microcontroller programmer you can get. It is really cute. Just a bit over 4cm x 1cm.

It emulates a stk500v2 on a virtual com-port.
The main features of the avrusb500 SMD programmer are:

Fast programmer with USB interface.
Recongnizes when the connector to the target is inserted with incorrect polarity.
Recongnizes when the connector to the target is not connected.
An orange LED indicates when the programmer communicates with the target.
Works with almost any system (Windows, Linux, Mac, ...)
Ready to use.
Tiny, light, but rigit and made for day to day use.
Can programm devices from 1.8V to 5.5V thanks to integrated level shift circuits.

The kit includes:

The AvrUsb500 SMD programmer.
The bootable CD, tuxgraphics Linux AVR programming CD
An appropriate socket to connect the programmer cable.
A 1.5m long USB cable to connect the programmer to your computer.
A 30cm long cable to connect to the target.

This programmer is OS independent (stk500 V2 protocol) and can flash any Atmel avr microcontroller with In-System Programming capabilities. The smd components are sealed in a transparent plastic to protect them against physical impact.

The device comes with firmware loaded. The firmware can, due to the device's size, not be changed. It has however configuration possibilities via serial terminal. The CD includes all needed drivers for Windows, MacOSX (on PowerPC and Intel) and a the avr-gcc development environment on a Knoppix CD.

ATmega8, PDIP (ATMEGA8-16PU)

The ATMega 8 AVR-RISC-Microcontroller. Package: DIL-28, 8K Flash memory, 512 bytes EEPROM, 1K S-Ram, 4.5-5.5 V, max. 16 MHz. Lead free.

price for one ATmega8: 2.10 Euro [convert_currency]

package with 3 ATmega8: 5.10 Euro [convert_currency]
(= 1.70 Euro per ATmega8)

Note: the atmega168/atmega88 microcontrollers are available on the ethernet page. The atmega8 and the atmega168/atmega88 are similar but they are not the same. You need the right controller for the right circuit.

5V mini power supply, USB, (power for experiments on the road)

This small power supply provides approximatley 5V and uses a USB port as power source.

The short circuit protection in this power supply has a highly non linear internal resistance to protect the USB port of your computer.

To just use a straight USB cable as "power supply" is a potentialy high risk for your PC. This cable has a small SMD circuit which protects your computer against "mistakes". It's short circuit protection comes in around 200mA. A bright red LED goes on as soon as a short circuit is detected.

This cable should be plugged directly into a USB port at the computer (not a passive hub).

Adapter cable for our programmer socket (to use any programmer hardware with our PCBs and kits)

Our programmer connector is very small, durable, easy to plug-in and fits into standard prototype breadboards. It is ideal for a temporary connection. Not all other vendors use such a nice solution.

This connector comes with a 8 cm long cable. It is just right to build your own adapter cable and re-use any existing ISP-programmer from other vendors with our hobby electronic kits.

This item includes:
- 5 pin gold plated connector with a short 8 cm cable. One outer pin is marked.

price: 2.49 Euro [convert_currency]

Adapter: tuxgraphics programmer to atmel 10pin connector (use our programmers with atmel development boards)

This is an adapter for the quite common and rather bulky 10 pin ISP-programmer plug.

This item includes:
- 10 pin programmer connector to tuxgraphics 5 pin socket
- the cable is about 6 cm long

Instead of buying it you can also build this adapter yourself: Circuit diagram, 10-pin-adapter.gif
