The SparkFun AutoDriver board is based on the STMicro L6470 dSPIN stepper motor driver. This powerful chip allows you to control a stepper motor with a voltage from 8 to 45V at 3Arms over an SPI connection. The AutoDriver board has been designed to be easily integrated into a project, even with multiple boards. Just connect your motors and your SPI-capable microcontroller and get steppin'!
STMicro’s L6470 is a 3A, 8–45V bipolar stepper motor driver. It has built-in overcurrent detection, undervoltage detection, overtemperature detection, stall detection, a 5-bit ADC, and a switch input that can be used for either user jog control or as a hard stop function. As if that weren’t enough, it also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting. Please keep in mind that the L6470 requires a great deal more configuration and adds software complexity to your system.
Unlike most stepper motor drivers, the dSPIN is controlled over an SPI link. It has an onboard 16MHz oscillator, which allows it to autonomously execute movement commands. That means no more counting steps in your code! It also supports customized acceleration and deceleration profiles to prevent jerky starts and stops. Onboard registers track current speed and location.
This new version of the SparkFun AutoDriver’s hardware is slightly different from the previous revision. It has been modified to make it easier to daisy-chain multiple boards together with simple 10-conductor ribbon cables for data and 6-conductor ribbon cables for control. The library has been updated as well, with more information found in the Hookup Guide below.
The logic supply voltage supports both 3.3V and 5V I/O levels.

所述SparkFun AutoDriver板是基於意法半導體L6470 dSPIN步進電機驅動器。這個強大的芯片允許你在3A RMS通過一個SPI連接控制從8至45V的電壓步進電機。該AutoDriver板設計可以很容易地集成到一個項目中，甚至多塊電路板。只需連接您的電機和您的SPI功能的微控制器，並獲得墊腳！
意法半導體的L6470是一款3A，8-45V雙極步進電機驅動器。它內置過電流檢測，欠壓檢測，過熱檢測，停轉檢測，有5位ADC，以及可用於任何用戶點動控制或作為硬停止功能的開關輸入。如果這還不夠，還設有微支持（每整步128微步）和PWM驅動電壓限制。請記住，在L6470需要更大量的配置，並增加了軟件的複雜性到系統中。
與大多數步進電機驅動器，dSPIN是通過一個SPI連接控制。它有一個板載16MHz的振盪器，這使得它能夠自主地執行移動命令。這意味著，在你的代碼不計數的步驟！它還支持自定義的加速和減速曲線，防止幹啟動和停止。板載寄存器跟踪當前的速度和位置。
這個新SparkFun AutoDriver的硬件版本是從以前的版本略有不同。它已被修改，使其更容易以菊花鏈的多個電路板與用於控制數據和6芯帶狀電纜簡單的10芯帶狀電纜在一起。該庫已更新，以及，與下面的接管手冊中找到更多信息。
邏輯電源電壓支持3.3V和5V的I / O電平。
