what chips can be used on a T4 board

Hi guys,

Im relatively new to programming and micro-controllers.
I have a Picaxe T4 training board with a 18M2 chip.
My question is can I use smaller chips on this board or will it only work with 18 pin chips.
I have searched before but couldn't really find the answer.
Cheers

The 18M2 has it's power connections in a different place than most Picaxe chips - so you are stuck with 18M2 chips in the T4 board really :confused: Good chip though!

Of course! I never even thought of looking at that. Do I need a board from Picaxe to programme chips or could I just stick it in a bread board and programme from there.

The T4 Trainer has a programming socket on-board so you can program your PICAXE in situ on the T4. All you need is a suitable download cable.

Hello, yup I have programmed an 18M2 already but I mean with regards to chips that do not fit on the T4 board

If you have a look at the PICAXE pinouts
Here:http://www.picaxe.com/What-is-PICAXE/PICAXE-Pinouts/
Or in the PICAXE manual1 around page 9 onwards
You will see that not only are the SerialIn/SerialOUT pins at different locations compared with othe M2 parts but also the power pins are at different locations.

Therefore even if you programmed a different M2 part on say a breadboard, you could not plug it into the T4 board and have it work.

Cheers for the info. I will take a look. No worries I will programme other chips via a bread board, was just curious, never thought of power pins being different and the like.

I only tend to use 08M2's, 14M2's & 20M2's for my project work.

They can all be programmed in the same 20 pin ZIF socket.

(have used a few 18M2's for serial LCD & OLED displays though).

I am not familiar with a ZIF socket, forgive my ignorance but can I plug my axe027 cable into that or does the ZIF go on a bread board?

Zif socket is socket that let's you plug micro chips into it. So instead of soldering a chip on a board, you can solder a zif socket and if the Chip goes bad you just pull it off and stick in a new Chip. Google is your best friend some times.

To clarify a bit further - ZIF is for Zero Insertion Force - it's a fancy socket with a lever that clamps and unclamps to the IC allowing very little wear on the chip. I often just use a regular socket and pry the IC out carefully - but if you need frequent changes ZIF is the way to go...

For the small 08M2 boards, just get one of these Picaxe project boards:
http://www.picaxe.com/Hardware/Project-Boards/PICAXE-08-Proto-Board/

I have used several of these in projects, they are very small so they fit into lots of enclosures, and it's surprising what you can do with an 8-pin chip and a little ingenuity.

Or, for a little more cash,

8, 14 and 20 pin capability.

And, for the full Monty,
