In addition to components shown on the page 12 of the schematic diagram, install DC connector J1P, C28P, C27P, on-off switch SW1, and two ferrite beads FB3P and FB4P. Those components are located at the top right corner of G11 PCB.
Also, install R11U, L1U, L2U and FB1U thorough-hole components. Don't forget to install all 4 LED diodes which are located at the bottom left part of PCB: LD1U, LD1S, LD2U, and LD3U.
Your G11 is now ready for first power-up. Apply 13.5V DC and check voltage on the U3U [5V]
Here is the photo of completed assembly:
Next step: connecting the G11 to GSDR and firmware update.
