GoGo 2.2d (Sep 17, 2003) ========================== - Fixed the problem that prevented the board to function properly with the battery pack. - Moved the 0.1 uF cap that is on the power line to a new location. This prevents it from creating noise in the power line. - The output ports now draws power from the regulated supply. This means it will always output 5V regardless of the input voltage. GoGo 2.2c (Aug 10, 2003) ========================== - Added a 3.3k pull-down resistor on the RX input to the hex inverter. This prevents the board from freezing when the serial cable is disconnected. - GND and VDD routings have been optimized to minimize signal noise. - Added a 0.1 uF accross GND and VDD lines to reduce noise. GoGo 2.2b (Aug 7, 2003) ========================== - 100uF Cap footprint changed from Radial to Axial. Should make it firmer. - The tip of the 5V Reg now can be soldered to the board. Should make if firmer. - Labels added for all components on the silkscreen layer. GoGo 2.2a ========================== - The gound is now traces rather than a fill. GoGo 2.2 ========================== - The extension bus is now I2C. - Memory and RTC added to the I2C bus.
