前一段看到LV8729的驱动板了，土豪朋当时是149一个买的
昨天打印机的E1驱动板坏了，drv8825的，换上了A4988用，觉得浑身不自在
在某宝上看到这个土豪的驱动板，有爱心人士做了爱心价，于是买了6个
打算把两个打印机全换上

FEATURES OF ccDriver
LV8729V chip
Motor voltage 10 – 25V
Motor current 0 to 1.8 A adjustable via potentiometer (V-REF)
Up to 128 micro steps possible (recommended maximum of 64 micro steps for 8-bit electronics, such as Arduino Mega with RAMPS.)
Short Circuit Shutdown
Pre-installed heat sink
The size corresponds to the popular Pololu drivers and the pinout is compatible but not identical.
Max 1/128 micro stepping when used in combination with 32-bits controllers that supports 1/128 micro stepping
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.
CAUTION: Inverted activation signal Enable = HIGH (at Pololu drivers enable = LOW, invert in firmware!)
