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.

Possible digital input device types:
Button: Regular button, game controller holds signal high if button is pressed.
Encoder: Each detent from encoder is shown as pulse from game controller. Pulsed game controller signal depends on turning direction.
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.


Analog inputs

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.

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.

Rechargeable version

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.

Non-rechargeable version

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.

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.
