The Tiny autopilot was designed with an end user application in mind.
#REDIRECT [[Tiny/v1.1]]
 
== Features ==
 
* Single LPC2148 MCU
* 8 Analog input channels 0V - 3.3V
* 1 3.3V TTL UART (5V tolerant)
* 7 PWM outputs
* 1 R/C receiver PWM frame input
* 1 [http://en.wikipedia.org/wiki/Serial_Peripheral_Interface SPI] bus
* 1 [http://en.wikipedia.org/wiki/I2c I<sup>2</sup>C] bus
* 1 USB (client)
* Integrated GPS receiver and patch antenna (4Hz update)
* 5V/2A switching power supply & 3.3V linear regulator
* 2 LEDs (status display)
* 1 button (initiate launch)
* 25 grams
* 63 x 35mm
 
The Tiny autopilot uses 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].
