Hi,

I have just bought this module,

If you manage to make it work, Can you confirm  the wiring given on https://www.dfrobot.com/product-2611.html: 

Wiring：Black-VCC，White-UART_RX，Yellow-UART_TX，Red-GND

I't not a typing error for Black-VCC and Red-GND ?

it is not a standard use

thank you in advance for your help

Thanks for Wiring image.

I'll be able to test more soon
