Boards using the CH552T

30 boards

Boards in 22 GitHub repositories, designed in KiCad, that use the CH552T by WCH (Nanjing Qinheng Microelectronics) (-40℃~+85℃ 12Mbps 3.3V~5V USB 2.0 USB to UART、USB to SPI TSSOP-20 USB Converters ROHS). See how each wires it, with its parts, size, README and files; the CH552T’s symbol, footprint and pinout are on its own page.
