Will use the new sdk for the f1c200s after working on the T113-S4,it was able to run at 36mA@5V no load after testing it was a very low current. I plan to install axp202 PMU chip for it there is also 128M/256M/512M SPI Nand Flash it works fine except for not having a fast transfer rate, allowing it to have handheld features like installing a Li-ion battery and having a power meter.

The pcb and 7” display test pcb are back.
