PICAXE Chips

PICAXE Brand: PICAXE
<P><B>PICAXE</B> is a microcontroller system that uses low cost FLASH memory based microcontrollers with a unique, pre-programmed <B>PICAXE</B> bootstrap code. This gives a device that may be reprogrammed typically 100,000 times without the need for an expensive and complicated programmer. <B>PICAXE</B> is programmed using a simple BASIC language or via the <B>Logicator</B> flowcharting software. Windows, Mac and Linux are all supported by the free BASIC software which can be downloaded from <U>www.picaxe.co.uk</U>.<BR><BR>Programming is carried out via a simple USB lead (<B><A href="/13-0849">13-0849</B></A>) or serial (<B><A href="/13-0847">13-0847</B></A>) cable. In addition to the microcontroller chips, starter, tutorial, and upgrade kits are available to provide a complete <B>PICAXE</B> solution. <B>PICAXE</B> microcontroller chips are available in 8, 14, 18, 20 and 28-pin versions, giving a choice of the number of input and output lines, and also in several variants which offer differing amounts of memory and extra features so a choice can be made according to project need.</P>
  • Suitable for education, industry and hobbyists
  • Low cost and simple to use
  • Wide range of variants
  • Can be programmed using an intuitive graphical flowchart
  • Free, easy to use Programming Editor software
NOTE: See also the PICAXE X2 chips section for the X2 variant PICAXE chips.

Q. Can i use a 9v battery for these picaxe chips, if not what do i need to reduce that volatage?
A. Hi, thank you for your question. Picaxe runs between 4.5 – 5V max- if connected to a 9V battery they will be destroyed. The simplest way would be to have two identical - high value resistors set up as a potential divider then the 4.5V can be tapped off from the junction of the 2. Easier yet is to use the correct voltage if possible using 3x AA batteries.

Q. What does 08M, 08M2, 14M2, 20M etc all mean? Also, what is the difference between 08, 08M and 08M2?
A. Hi Freddie. Thank you for your question. Further information regarding Picaxe chip sizes can be found here.

Q. Can you use circuit wizard to programme these chips?
A. Hi Jack. Thank you for your question. Circuit wizard is aimed at the genie range of microcontrollers. Genie is similar to picaxe but not the same. To program picaxe you need the free programming editor software or pic logicator software. They are different systems.

Q. What is the difference between picaxe chips and the pic microcontrollers?
A. Hi Jack. Thank you for your question. The picaxe chips are not blank. They carry some bootstrap code to allow programming via a simple serial cable. This eliminates the use of a programmer for educational use. Non picaxe PIC chips are designed to be used with a programmer. These are cheaper and are what is used in industry. However these require assembly language programming and the initial outlay for a programmer and software can be expensive. Picaxe allows programming in BASIC and the software is free to download. No programmer is needed so it allows the use of microcontrollers in schools and makes it more available to hobbyists.


03 February 2013 Question by: Rapid Customer
Q. Are all the chips 10 bits or only some of them
A. Hi Matty, Thank you for your question. All have 10 bit adc (expect 08, 18, 18A, 28, 28A, 28X, 40X).

Q. Are you selling the Newer 18m2+? Has the product code not changed?
A. Hi MJ. Thank you for your question. We do sell the 18m2+: 13-5026 DIL and 13-5050 SMD.


23 November 2012 Question by: Rapid Customer
Q. Hi, is the 18M2 the 18M2+ version?
A. Hi Steve. Thank you for your question. 18M2+ is the updated version however in the software select 18M2.
