Description

A new version of the UA4C (vB1 Sea Fox) is available
Changes include:

– Rearranging the serial headers for better fitment in the slim case
– Upgrading the low current outputs, they now support larger loads and are self-protecting
– Changed tachometer circuit to allow 5V, 12V, and high voltage tachometers
– Added indicator LED for 5V power, and improved labeling

The UA4C uses SMD technology to make a 4 ignition/4 injection channel board smaller, with more features, and cheaper. It is a bottom mounted Arduino MEGA shield. The MEGA is placed upside down on top of it.* This makes the total package thickness less than 20mm. All of the outputs (except for stepper idle) include an LED for quick troubleshooting during setup. An externally accessible jumper blocks resetting of the system when a USB cable is connected. Wire housings and 50 (four extra) terminals are included to connect your wiring to the PCB. Will fit in the slim or standard height Hammond case. If you include soldering service the sensors, connectors, etc will be soldered to the board. If you require special provisions you can email turboedge at this website.com.

Outputs

– 4 ignition channels, logic 5V, 330mA max pulse
– 4 injector channels, ground switching
– 4 high current outputs (idle, idle2, boost, vvt) ground switching
– 8 low current outputs (fuel pump, tachometer, fan, fan2, aux1-4) ground switching
– Accepts DRV8825 module for stepper idle control

Inputs

– 2 triggers (crank, cam, etc, logic level with socket for conditioner modules)
– MAP (250 or 400kPa) and separate barometer
– Voltage correction
– Throttle position
– Coolant and incoming air temperature
– Oxygen
– Flex fuel
– Launch
– Knock (future code update)
– 2 spare inputs

Communications

– Bluetooth header with blocking diode to allow use of USB

Extra Stuff

NOTICE: This is an unofficial Speeduino board. Josh Stewart was very kind in adding a definition for this board to the Speeduino code. However, purchases of this board do not directly contribute to his upkeep and updates to the Speeduino software and website. PLEASE consider visiting Speeduino Forum and clicking Support Speeduino at the top.

*In order for the MEGA to fit the unused power jack must be removed. To do this use a pair of side cutters and cut the metal strap on the jack closest to the outside edge of the Arduino board. Then use a pair of slip-joint pliers to twist the jack back and forth while pulling it away from the PCB. It should come off fairly easily, but please take care when doing so. I will assume no responsibility for Arduino, bodily, or other harm. If you order an Arduino MEGA from me this will be done already.
