PICAXE

[1] PICAXE microcontrollers are pre-programmed with an interpreter[2] similar to the BASIC Stamp but using internal EEPROM instead, thus reducing cost.

[15] All current PICAXEs have commands for using hardware features of the underlying PIC microcontrollers: All current PICAXE chips have at least 2048 bytes of on board program memory available for user programs:[1] The default clock speed for all M2 and X1 parts is 4 MHz and for the X2 parts is 8 MHz.

[28] Project boards for different applications are sold[29] by Rev-Ed which contain the PICAXE, download circuit and may also contain a prototyping area[30] or high power output drivers.

PICAXE Programming Editor features:[32] AXEpad is a cross-platform application recommended for Linux and Mac users.

[34] The Logicator web page is out of date as the free version does support all commands but shows nag screens.
