The OpenServo Version 3 is the latest in the OpenServo range. There are many new features, and more on the way.
- Independent H-Bridge allowing for braking
- Temperature sensor
- Fast 20MHZ clock speed
- 400khz I2C/TWI interface
The OpenServo platform was designed to run from a NiCad R/C battery pack which generally outputs 6v-7.2v. The standard V3.x OpenServo adapts to any input voltage from 6 VDC to 7.5 VDC. (Some people have soldered in some modifications that work at test voltages as low as 3.3 V) see "Why does the OpenServo need at least 6V to run?" ServoFAQ#line-33; "Why +6V ( Six Volts ) Instead of +5V ( Five Volts )?".
output current: can drive servos with up to 15 ? A peak, 3 ? A continuous (the OpenServo limits the current, so it doesn't hurt if you put it on bigger servos). (Some people have soldered in higher-current transistors).
New firmware will bring additional features in the future
