3.c. Included HardwareThe qik ships with a 12×1 straight 0.100" male header strip [http://www.pololu.com/catalog/product/965], a 3×2straight 0.10

The 3×2 header strip can be soldered to the jumper pins as shown above, which lets you make use of the includedshorting blocks, and the included termi

3.f. Board Dimensions and Mounting InformationThe qik 2s12v10 measures 2.15" x 1.86" x 0.28" (54.6 x 47.2 x 7.1 mm) and weighs 0.5 oz (

4. Serial InterfaceYou can use the serial interface for three general purposes: querying the qik for information, setting itsconfiguration parameters,

information. Information requests result in the transmission of a single byte per request. If you aren’t interested inreceiving feedback from the qik,

For example, if we want to set motor M1 to full speed forward using the compact protocol, we could send thefollowing byte sequence:in hex: 0x8D, 0x7Fi

If you want to daisy-chain a qik with other Pololu devices that use 0x80 as an initial command byte, theprocedure becomes slightly more complicated. Y
