UINIO USB Serial
uinika/UINIO-USB-Serial
A Serial Protocol Converter base on CH347T related I2C & SPI and so on.

The CH347T is a USB Converter made by WCH (Nanjing Qinheng Microelectronics) in a TSSOP-20 package with 20 pins. -40℃~+85℃ 2 3V、3.3V、3.6V 9Mbps USB 2.0 USB to UART、USB to SPI、USB to I2C、USB to JTAG TSSOP-20 USB Converters ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CH347T, from EasyEDA) and its footprint (Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm, from KiCad's library), ready for a KiCad board. 1,030 are in stock at JLCPCB (part C5122332). 8 open-source boards in 8 repositories on GitHub use it.
