Application Schematic

 

    This schematic is demonstrated how to using UNO Core create 3-ch analog voltage , here we need a PWM to DAC module DAC-3000 , UNO Core use AnalogWrite function to create 3 ch PWM signal and DAC-3000 will converter the PWM to analog output , the output is: Vout = (1-PWM%) * Vref . in here the DAC output range is 0 to 3.3V.
    The Pin24 (VCC_3V3) connected onboard LDO’s output, it will share 3.3V with the module circuit , so the VCC_3V3 Load current have to limited within 300mA , otherwise it will lead the 3.3V unstable , or damaged the module.
    The UNO Core have a onboard RF module design(LC-2000,Clik to View) , the LC-2000 is a 2.4GHz RF UART module , it can be make UNO Core communication via 2.4GHz RF connection, but not all version will be install this module, Please notice the description, we have module number as below:
    UNO Core    :  without RF Module
    RF UNO Core  :  with RF Module(Click to View)

 

Upload sketch and communication

 

    RF UNO Core can be uploading sketch and communication via 2.4GHz RF connection , user need a USB Dongle on PC side and we call it LC-2000U , we will release this product in Jan.2016.
    Both RF UNO Core and UNO Core have a onboard UART connector , it’s a 6-Pin 2.0mm Female connector, user can be use stand USB2Serial Light cable to upload and communication with a 2.5mm to 2.0mm convertor. We also provide UC-2102 kit for this usage.
