FEATURES OF ccDriver<\/div>\n
LV8729V chip<\/div>\n
Motor voltage 10 \u2013 25V<\/div>\n
Motor current 0 to 1.8 A adjustable via potentiometer (V-REF)<\/div>\n
Up to 128 micro steps possible (recommended maximum of 64 micro steps for 8-bit electronics, such as Arduino Mega with RAMPS.)<\/div>\n
Short Circuit Shutdown<\/div>\n
Pre-installed heat sink<\/div>\n
The size corresponds to the popular Pololu drivers and the pinout is compatible but not identical.<\/div>\n
Max 1\/128 micro stepping when used in combination with \u00a032-bits controllers that supports 1\/128 micro stepping<\/div>\n
Can be used on RAMPS, rumba and other RepRap electronics, but 8-bit electronics usually are too slow for 1\/64 and 1\/128 micro stepping.<\/div>\n
CAUTION: Inverted activation signal Enable = HIGH (at Pololu drivers enable = LOW, invert in firmware!)<\/div>\n
