Trying to get this PCB built up. I have the design done. I need to order PCB and parts. Will share it when tested and working. Will also put available for sale in my tindie store. Will be open source. Its a prototyping tool. USB with a USB 2 UART and USB MicroSD card reader with a controllable switch to allow MicroSD for MCU usage . Also has a 3.3v and 5v supply and LIPO Charger. Would be a great tool to have on a work bench.
