<h1>The Under Arduino 4 Channel boards made for Speeduino share the following features</h1>
|
||
<h4> </h4>
|
||
<h4>Outputs</h4>
|
||
<p>– 4 ignition channels, logic 5V, 330mA max pulse<br>– 4 injector channels, ground switching<br>– 4 high current outputs (idle, idle2, boost, vvt) ground switching<br>– 8 low current outputs (fuel pump, tachometer, fan, fan2, aux1-4) ground switching<br>– Accepts DRV8825 module for stepper idle control</p>
|
||
<h4>Inputs</h4>
|
||
<p>– 2 triggers (crank, cam, etc, logic level with socket for conditioner modules)<br>– MAP (250 or 400kPa) and separate barometer<br>– Voltage correction<br>– Throttle position<br>– Coolant and incoming air temperature<br>– Oxygen<br>– Flex fuel<br>– Launch<br>– Knock (future code update)<br>– 2 spare inputs</p>
|
||
<h4>Communications</h4>
|
||
<p>– Serial3 routed to external connector (optional CAN with future module)<br>– Bluetooth header with blocking diode to allow use of USB</p>
|
||
<p> </p>
|
||
<h4>Version vB3 Sea Fox changes include:</h4>
|
||
<p>-All boards now ship with 400kPa MAP sensors for no limit boosting </p>
|
||
<p>-Minor component/placement adjustments</p>
|
||
<p>-Further improved labeling</p>
|
||
<p>-Assembled in the USA</p>
|
||
<p> </p>
|
||
<h4>Version vB2 Sea Fox changes include:</h4>
|
||
<p>-All SMD components including the sensors are now soldered on from the factory<br>-5 volt output is protected from overload<br>-Corrected parallel install issue<br>-Harness connector footprint improved to better hold the connector while soldering<br>-Further improved labeling<br>-Assembled in the USA</p>
|
||
<p> </p>
|
||
<h4>A new version of the UA4C (vB1 Sea Fox) is available<br>Changes include:</h4>
|
||
<p>– Rearranging the serial headers for better fitment in the slim case<br>– Upgrading the low current outputs, they now support larger loads and are self-protecting<br>– Changed tachometer circuit to allow 5V, 12V, and high voltage tachometers<br>– Added indicator LED for 5V power, and improved labeling</p>
