The complete re-design of the popular Tiny autopilot was done on October 9, 2007. The new design is not a bug-fix as no known flaws exist with the current 0.99 and 1.1 versions, so the redesign is performance, easy to use and easy to assemble-oriented !

The Tiny v2.1 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.
 
=== Feature additions : Tiny 2.1 vs Tiny 1.1 ===
 
* Hardware flow control on the modem
: The LPC has one "full-featured" serial port and one basic serial port.
::Tiny v1.1 had the full-featured port hard-wired to the GPS in order to leave the basic port open for initial bootloader programming.
::Tiny v2.1 exchange these ports and use the GPS Reset signal to "disconnect" the GPS for the one-time bootloader programming. Hardware flow control on the modem is now possible.
 
* 5V switching power supply
::The Texas Instruments [http://focus.ti.com/docs/prod/folders/print/pth08080w.html PTH08080WAH] switching 5V/2.25A integrated power supply module greatly simplify manufacturing, reduce costs, and improve performance.
::Tiny v2.1 have a voltage input range of 6.1V &rarr; 18V and enough 5V power for large servos, high-power modems and video systems.
 
* 3.3V linear regulator
:Tiny v2.1 use a [http://www.national.com/mpf/LM/LM3940.html LM3940] 1A regulator for 5V to 3.3V conversion in a SOT223 standard pinout package which is capable of providing plenty of power to modems or other devices.
:Tests have shown that any device with irregular power consumption can cause significant voltage fluctuations on the critical 3.3V bus.
:Users are advised to use a separate regulator as needed for such devices.
 
* Video/payload power switch.
:The TPS1100 transistor used on the Tiny v1.1 design has proven extremely useful but is intended for high-speed power switching of motor controllers and occupies a 5mm x 6mm space (SOIC-8).
:The replacement on the new Tiny v2.1 is a current-limiting switch TPS2051B intended for peripheral power control and should protect the 5V supply from voltage sags during the power-up of high capacitance peripherals as well as allow the 5V supply to continue working in the event of a complete short-circuit in the payload.
:: [http://www.digikey.com/scripts/DkSearch/dksus.dll?PName?Name=296-21265-1-ND&Site=US TPS2051BDBVR] Single 500mA (1A limited) switch in a 3mm x 3mm SOT23-5 package
 
* GPS ground plane and antenna
:The 13mm antenna on previous Tiny v1.1 proved to be an unworthy exchange of performance for weight. Crude parking-lot tests showed an approximate 3dBi loss (as expected from the data sheets), but the narrow bandwidth of the small antenna made it more sensitive to de-tuning from nearby components in the aircraft.  Flight performance was acceptable but poor climb rate calculations were observed with the smaller antenna.  Tiny 1.1 users are advised to fit a 20mm antenna.
::Tiny v2.1 use a 18mm x 4mm antenna (20mm x 4mm is possible but no more available) and feature 30% more ground plane area (40 x 40mm).
 
* GPS Reset
:Occasionally the GPS fails to boot properly, displays very poor S/N ratios, and fails to obtain a valid fix. This may be caused by a slow power-up of the 5V or 3V regulators, or by some unusual EMI that is only present at boot. Usually a simple power cycle will correct the problem but occasionally the receiver seems to use the backup battery to retain the bad state.
:: On the Tiny v2.1 design GPS reset is connected to a GPIO pin on the MCU and allow the operator to reset the GPS as needed.
 
*Headers
:Tiny v2.1 feature revised header layouts on all peripherals.
::*The modem header have CTS/RTS/DTR and both 5V and 3.3V supplies.(3.3V is shared with LPC and ADC channels - use with caution and only with very low power modems like the 10mW Xbee).
::*The Tiny v1.1 button is removed and it's function is combined on the USB header along with a LED trigger so that indicator, button, and USB can be remotely mounted.
::* Vertical Infrared (1 ADC) with 3.3v supply
::* Horizontal Infrared (2 ADC) with 3.3v supply
::* 2 general purpose ADC with both 3.3v and 5v supplies
::* 2 general purpose ADC with optional on-board resistor bridge and both 3.3v and 5v supplies
::* Two axis Camera control with two servo signal, vdo switch control, vdo power switch and both 5V and 3.3V supplies
::* SPI bus with 3.3V supply
::* I2C bus with both 5V and 3V supplies
 
* Leds & testpoints
:3 status LEDs with attached test point available on Tiny v2.1 design (instead 2 on Tiny v1.1)
 
* Components size
:Many users (not only beginners) don't really think that 0402 components on Tiny v1.1 is a great saving from any viewpoint. Even if one saves a little space by using these components, there must still be enough room around to solder it by hand with a soldering iron.
:Tiny v2.1 use 0603 components, the assembly should be a bit more friendly to everyone.
 
* Layers amount
:Tiny v2.1 2 Layer design (instead 4 Layers on Tiny v1.1) should simplify manufacturing and reduce costs.

== Programming ==
[[Image:Tiny_test_wiring.jpg|thumb|Example wiring for programming and telemetry]]
The Philips LPC21xx series ARM7 microcontrollers include hardware ISP (InCircuit Serial Programming) and can be programmed through the serial interface UART0 (labled "download" on the PCB) by holding pin P0.14 (count 5 pins in from outside of PCB on download connector) low during power-up and until USB boot code programming is completed. Note this is a 1x operation usually done by the person supplying the Tiny2.11 autopilot so you may want to ask if this was done from your Tiny2.11 vendor.
 
Once the USB boot code is loaded (see above) the Paparazzi software includes a USB bootloader program that allows for easy 1-second programming through a standard USB port (labeled "usb" on the PCB) with only a USB to Tiny Molex 8-pin adapter cable needed.  Using either the GUI (paparazzi) or command line arguments you can now upload new settings, flight plans, or software updates quickly and conveniently.  <br>See the [[Compiling|Compiling and Flashing]] page for more detailed instructions on installing the bootloader and autopilot software.
