Revision History - NEX ROBOTICS FIREBIRD V ATMEGA 2560 Hardware Manual

Revision History:

1. User must go through the Fire Bird V's Hardware and Software manuals
before using the robot.
This hardware manual is applicable from Main board Version 11 dated 12
2.
August 2012 onwards and ATMEGA2560 microcontroller board Version 7
dated 15 th August 2012.
Crystal of the ATMEGA2560 microcontroller is upgraded to 14.7456MHz
3.
from 11.0592Mhz in all the Fire Bird V ATMEGA2560 robots delivered on
or after 1 st
crystal frequency as 14.7456MHz.
Following are the upgrades made in Main board Version 11 dated 12
4.
August 2012 and ATMEGA2560 microcontroller board Version 7 dated 15
August 2012.
• Main board supports any microcontroller working on 3.3V and 5V.
• On-board NiMH Battery charger along with battery level indicator.
• Auxiliary power connector and battery charging connectors are separated
and require a single unified connector from the AC adapter.
• 3mm IR proximity Sensors are replaced with 5mm IR Proximity sensor for
better range.
• 3 times reduction in power consumed by IR proximity sensors.
• Added support for 7 channel white line sensors with all 7 sensor calibration
potentiometers on main board.
• All Motor, Sensor pod & battery connectors are replaced with relimate 2510
type connectors for better reliability.
