The Simucube Wireless Wheel 2 Module is an upgraded version of the Simucube Wireless wheel module. New module offers more digital inputs, 4 analog axis, in-build battery charger and voltage regulator.

=Digital inputs=
Wireless Wheel 2 Module has a total of 98 digital input pins in which 96 inputs are fully configurable by wheel manufacturers. 2 pins are reserved for shifter paddles. Shifter paddles are only mandatory devices, and the rest of the pins can be used as needed. Paddles are mandatory, since those are used to connect and disconnect wheel from Simucube. Each configurable IO pin can be used multiple times with different device types. Most of the input devices can also be configured with enable pins. These enable pins can be used to multiplex encoders. For example, one encoder can be configured as 12 different encoders with rotary switch controlling which encoder is used at time.<br><br>
<u>'''Possible digital input device types:'''</u><br>
'''Button:''' Regular button, game controller holds signal high if button is pressed.<br>
'''Encoder:''' Each detent from encoder is shown as pulse from game controller. Pulsed game controller signal depends on turning direction.<br>
'''Rotary switch:''' Maximum of 12 positions. Changing switch position will pulse corresponding output. Rotary switch can also be configured as buttons, if pulsing output is not needed or wanted.<br>



=Analog inputs=
[[file:SLEEP_pin_controlled_output.png|thumbnail|upright|left|SLEEP pin with transistors can be used to turn external devices on and off]]
The wireless module offers AVCC output for analog devices. Output in AVCC is pulsed for lower power consumption and output is on only when the ADC module is sampling inputs. Output pulses are 2ms long and frequency is 100Hz, this means that AVCC is on 20% of the time. 2ms pulses work great with potentiometers, but Hall-effect sensors might not work with pulsed AVCC if Hall-sensor power-on time is too long. One option to provide VCC for Hall-sensor is to power it from Wireless Wheel 2 VDD pin and use MOSFETs connected to SLEEP pin so Hall-sensor can be powered off while Wireless Wheel 2 isn’t connected. SLEEP pin is high when Wireless Wheel 2 is connected to Simucube.
<br style="clear:both;" />

= Battery connections =

Wireless Wheel 2 Module has multiple VIN, GND, BATT, and SW_IN pins. The module will work when using only one of each, but it is recommended to connect pins together in the wheel circuit board. Pins should be tied together to ensure a reliable connection with the M.2 connector in case of mechanical shock or shaking.<br>
== Rechargeable version ==
[[file:rechargeable_wheel_example.png|thumbnail|upright|left|Rechargeable example]]
Wireless Wheel 2 Module for rechargeable batteries has an in-built charger circuit and DC-DC converter to regulate battery voltage to 3.0V. The charger is connected to VIN and should be provided with 5.0V +- 5% with a minimum of 450mA for charging. BATT pins are charger output and the battery should be connected between these and GND. SW_IN is unregulated voltage input for the Wireless Wheel 2 Module and will provide voltage to the in-built DC-DC converter. The power switch can be connected between SW_IN pins and a positive battery terminal. installing power switch between SW_IN and BATT enable charging when the wheel is turned off.<br>
<br style="clear:both;" />
== Non-rechargeable version ==
[[file:non-rechargeable_wheel_example.png|thumbnail|upright|left|Non-rechargeable example]] 

Wireless Wheel 2 Module version for non-rechargeable batteries does not have a charger nor DC-DC converter. Due to a non-existing DC-DC converter, the VDD output is not regulated, and voltage will be the same as battery voltage. Even though it is possible to connect batteries straight to SW_IN pins to power this version, it is recommended to connect battery positive lead to VIN instead, since it has reverse polarity protection. VIN is internally connected to BATT pins in a non-rechargeable version. If a power switch is needed, it can be installed on battery leads or between BATT and SW_IN pins. If the power switch is not connected between mentioned pins, BATT pins should be connected to WS_IN pins to ensure power for the module.<br>
<br style="clear:both;" />

= Pinout =
Wireless Wheel 2 Module uses M.2 connectors to fit all the I/O pins in a compact, low-profile packet.
All LED pins include a 220 Ohm current limiter resistor.

Two of the pins are reserved for shifter paddles that must be included in every steering wheel. Paddles are mandatory because they are used to connect and disconnect the wheel from Simucube. Each configurable input pin can be used multiple times with different device types. The input pins can also be used as '''''enable pins'''''. These '''''enable pins''''' can be used to enable and disable other devices.

-• <b>Rotary switch:</b> Maximum of 12 positions. Changing the switch position will send a pulse (100ms) to the corresponding output. <br>
-If the desired functionality is that the output is constantly on, the rotary switch can also be configured as regular buttons. This can also be done in addition to the default functionality if there are enough unused HID pins.<br>
-• <b>Simucube Button:</b> Holding down this button more than 1 second will start or stop Simucube Button mode. When at this mode, user can change Simucube force feedback paramerers using buttons and encoders from wheel.<br><br>
-===Simucube Button===
-Holding down the Simucube Button over one second will switch Simucube 2 to Simucube Button mode, where force feedback parameters can be changed using the Wireless Wheel.
-Sc Button mode is designed around a 7-way switch (“Funky Switch”) with an encoder and a five-way joystick. Other buttons can also be used, but it is recommended to keep layout similar between different wheels.
-When entering SC button mode, the overall strength parameter is selected by default. The adjusted parameter is selected by configurable buttons. Holding parameter selection down for more than 2 seconds will reset the parameter to the previous value (Last value set from True Drive).<br><br>

-The wireless module offers an AVCC output pin for analog devices. To reduce power consumption, the AVCC pin is pulsed so that the pin is only turned on when the ADC module is sampling inputs. Output pulses are approximately 2ms long, and the frequency is 100Hz; this means that AVCC is on 20% of the time. Pulses work great with potentiometers, but Hall-effect sensors might not work with pulsed AVCC if Hall-sensor power-on time is too long. As a result, any excess capacitance must be avoided in the AVCC pin. <br> <br>
