The new module comes in two different versions, which both offer more digital inputs and 4 analog axes. The non-rechargeable version is intended for endurance with a non-rechargeable battery, and the rechargeable version has an in-build charger and a voltage regulator. |

Each configurable input pin can be used multiple times with different device types. The input pins can also be used as '''''enable pins'''''.

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. This allows for advanced functionalities, t.ex. Using a physical encoder as 12 virtual encoders using a rotary switch or disabling unintentional center presses in a 5 or 7-way switch. |

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> | The wireless module offers an AVCC output pin for analog devices.

The charger is connected to VIN and should be provided with 5.0V +- 5% with a minimum of 450mA for charging (e.g. using a USB cable). BATT pins are charger output, and the battery should be connected between these and GND. SW_IN is unregulated voltage input for the Module and will provide voltage to the in-built DC-DC converter. The power switch must be connected between SW_IN pins and the positive battery terminal. installing a power switch between SW_IN and BATT enables charging when the wheel is turned off. |

Due to a non-existing DC-DC converter, all module voltages 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, which is internally connected to BATT pins in a non-rechargeable version and includes reverse polarity protection. If a power switch is needed, it can be installed on battery leads or between BATT and SW_IN pins. BATT pins should be connected to SW_IN pins to establish power for the module if the power switch is not connected between mentioned pins. |
