The ENAC team has been working on long endurance airplanes for a while now. It appeared that one of the many limitations was the integration of the electronic part into the new fuselages which are becoming thinner and thinner. So we started to work on a new version of autopilot mainly based on the well-known tiny. The new sensors becoming smaller and smaller, we were able to integrate onto the board the IMU and a new design of barometer. So now, the ENAC team is proud to present you the UMARIM! (which means "I Hope" in turkish)

'''WARNING:'''


'''''Download [[Media:Gerber_for_Umarim_v1-0.zip|Umarim v1.0 gerber & drill files (zip)]]'''''
'''Umarim requires care during assembly of the ITG3200. While most are assembled fine (PPZUAV, ENAC, a few individuals have self assembled Umarim v1) The tolerances between the pad and the pins are quite close. During reflow the IC should center itself fine. However if it does not center it could connect the pad to a pin(s). Simplest way to avoid this is to use non conducting IC tape under the IC on the big square pad when doing self assembly. '''

'''WARNING: THERE IS AN ERROR IN THESE GERBER FILES!'''
'''The footprint of the ITG3200 extends below the base of the IC.  Because the IC has a metal baseplate, this causes a 0.025mm tolerance on placement of the ITG-3200 which is almost impossible to achieve.  I an unable to correct the files because I don't have Protel.'''

The ENAC team has been working on long endurance airplanes for a while now. It appeared that one of the many limitations was the integration of the electronic part into the new fuselages which are becoming thinner and thinner. So we started to work on a new version of autopilot mainly based on the well-known tiny. The new sensors becoming smaller and smaller, we were able to integrate onto the board the IMU and a new design of barometer. So now, the ENAC team is proud to present you the UMARIM! (which means "I Hope" in turkish)

Gerber & Drill Files

WARNING:

Umarim requires care during assembly of the ITG3200. While most are assembled fine (PPZUAV, ENAC, a few individuals have self assembled Umarim v1) The tolerances between the pad and the pins are quite close. During reflow the IC should center itself fine. However if it does not center it could connect the pad to a pin(s). Simplest way to avoid this is to use non conducting IC tape under the IC on the big square pad when doing self assembly.

WARNING: THERE IS AN ERROR IN THESE GERBER FILES!

The footprint of the ITG3200 extends below the base of the IC. Because the IC has a metal baseplate, this causes a 0.025mm tolerance on placement of the ITG-3200 which is almost impossible to achieve. I an unable to correct the files because I don't have Protel.

Required components


Note1: It is advised to use FTDI USB-serial converter, as serial FTDI chips are by default working well in Linux.
The Paparazzi ground station software is configured to look for modems on FTDI ports by default.
This harness can also serve as a modem interface (after it's use in Bootloader uploading) if you plug it on Umarim's UART1 connector
