Hack your servo v3.00: Get full PID position and speed control from your servo

http://bit.do/deH3T Secret sale page at TerraPrivacy.
ATMega328P-based direct replacement boards for standard and ¼ scale rc-servos that will allow for full PID speed / position control of your servomotor. Motion profiles are of course supported and with a contol loop closing at 1Khz you will never be 'out of place'. The second generation of our Supermodified™ boards comes with 12-bit position encoding translating to 0.08° increments. The Magnetic Encoder (MagEnc™) is mounted directly onto your servo's output shaft and hence the backlash is acounted for! Powered by Freescales MC33887 IC capable of accommodating 5A continuous (and up to 7A bursts), the Supermodified™ is perfectly suited for hobby servos and small-to-medium DC motors. - overall dimensions 16x16x12 mm - can communicate via I2C or RS485 (also RS232) - directly Arduino compatible but 4MHz faster and with half the form factor of Arduino nano! - great AVR support libraries
