We offer a wide range of PICAXE Chips available in two series – M2 and X2. They are in six physical sizes (8, 14, 18, 20, 28, and 40 pins). Various PICAXE ICs are also available.
The M2 series chips are the industry standard, with up to 1800 lines of BASIC code and support for common interfacing protocols such as RS232 (serial), infrared, and I2C. They also support task parallelization. The X2 series has more memory capacity, allowing for longer programs and more variables (RAM).
