The Tiny Control Board use a single Philips LPC2148 ARM7 based microcontroller.
The [http://www.arm.com/products/CPUs/families/ARM7Family.html ARM7] is a low-power 32-bit RISC processor core and the [http://www.standardics.philips.com/products/lpc2000/ 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 [http://cvs.savannah.nongnu.org/viewcvs/paparazzi3/hw/controller/?root=paparazzi CVS repository].

The Tiny autopilot was designed with an end user application in mind.

Features

  • single LPC2148 MCU for onboard computation
  • 8 ADC channels
  • 1 UART
  • 7 PWM outputs
  • 1 RC receiver input
  • 1 SPI
  • 1 I^2^C
  • 1 USB client
  • GPS Receiver (from U-Blox) and integrated GPS patch Antenna
  • 5V/2A built in switching power supply & 3.3V linear regulator
  • 2 LEDs (status display)
  • 1 button (initiate launch)
  • 25 grams
  • 63 x 35mm

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.
