The Tiny Control Board use a single Philips LPC2148 ARM7 based microcontroller. The ARM7 is a low-power 32-bit RISC processor core and the Philips LPC2148 has 512KB on-chip Flash ROM, 40KB RAM and can be clocked at 60MHz.

Although critical control code such as the R/C interface and servo output are well segregated in Paparazzi software and well protected from interference from flaws in the stability/navigation/comm/payload code, great care must be taken when experimenting with new software as some errors can cause a the processor to halt or stall for extended periods causing total loss of control. The dual processor Classix addresses this risk by runnning critical code on a separate independent processor.

The schematics are available from the CVS repository.
