3 Hardware Description
Rd-03E supported hardware is Xen102. Figure 3-1 is a photo of the front and back of the
Rd-03E. Five pin holes J2 are reserved for the Rd-03E hardware (no pin is provided at the
factory), which are the power supply and communication interface. The MCU burning port is
called J3. Please connect according to the corresponding pin name when burning. (J1 is
reserved for USB interface, which is not introduced in this document for the time being.)
