The FPGA part is exactly the same as the RK3506G2+XC6SLX25 core board.

T113-S4 integrates MIC, and the NGFF interface part leads to 4Lanes MIPI DSI/2XUSB/1x1000Mbps PHY/SDIO/audio headphone output/18xIO/1xGPADC.

We will upload the Kicad schematic, but the Kicad file of the PCB will not be open source for commercial reasons.

It is already in the PCB production process and will soon be able to come back for welding.

I received the empty PCB.

The component on the back has been welded, and the 0201 component is challenging.

The components on the front of the PCB are installed. We have tested the functions of FPGA and DDR3. It works normally. The next step is to test the function of T113-S4.

The output resolution of T113-S4 can reach 1920x1200, so it can drive the display of multiple screens relatively well.

We have updated the design of LCD PCB, installed 6 more FPCs to connect the LCD expansion board, and T113 can also be installed and used.
