※1. When using TWELITE overseas, there may be various restrictions such as permitted antennas. Please consult us in the early stage of development.

※2. Depending on the country, it may be necessary to display FCC ID, IC ID, etc. on TWELITE or the product. If you think this applies, please contact us.

Notes on Export

The built-in AES 128bit encryption circuit in TWELITE is subject to export control judgment. When exporting, we will issue an export control certificate, so please contact us.
In some countries, customs clearance may not be possible unless TWELITE has obtained radio certification in the exporting country. Please inquire about regulations for each country.

Product Labeling

The product bears product logos, certification numbers, etc., but these may change without notice.

*1. Pin number. Different from TWELITE (SMD version) in numbering and assignment. Use IO Name to identify pins.
*2. IO Name is the pin’s defined name, used in semiconductor datasheets and TWELITE app development. This is also the default naming used in our technical support.
*3. Each pin can be used for general input/output or analog input, but can also be initialized via API to assign alternative functions. This column lists representative assignments.
*4. Functions listed here are available when the pin is initialized via API for alternate use.
*5. Function names specific to the “Extremely Simple! Standard App” (App_Twelite). These may resemble IO names but are distinct.
*6. PWM2 and PWM3 can be reassigned from DIO6,7 or DIO12,13 to DO0,1.
*7. ADC5 and ADC6 are available only on TWELITE RED.

Handling of Special Pins

DO0 (Function Name: SPICLK)

This pin is used as an output pin. Applying voltage externally (even with some output impedance) has been reported to prevent the TWE module from entering program mode.
When connecting LEDs or transistors, the pin may be in an intermediate state at startup or when waking from sleep, causing abnormal operation. It is recommended to always use an external circuit that pulls up to Vcc.

DO1 (Function Name: SPIMISO)

This pin is often used as an output pin, but at module power-on or reset it behaves as an input. If a low voltage is detected at that time, the module starts in program mode. Please pay attention to the voltage at startup on this pin.

DIO0 (Function Name: ADC3), DIO1 (Function Name: ADC4)

These pins are shared with analog input. In firmware, internal pull-up must be disabled when reading AD values .

ADC2

ADC2 can be used as an input for reference voltage. Software implementation is required to use this. Note, there is no pin that outputs the reference voltage.

GND

It is recommended to connect both pins 1 and 14 to GND, but it is also possible to operate with one unconnected. No significant change in wireless performance has been observed even if either is left unconnected.
