Usb uart shift
About the Usb uart shift PCB
Usb uart shift is an open source PCB design by florolf, published on GitHub. It is a 2-layer board measuring 34.4 × 16 mm, with 40 components from 17 distinct parts.
Other key parts include the C85364, FT230XQ-R and SN74LVC1T45DCKR. By type, the board carries 14 capacitors, 14 resistors, 6 ICs, 3 connectors, 2 diodes and 1 inductor.
From the project
USB->UART adapter with level shifting
This is an FT230X-based USB-UART adapter with built-in level shifting. This allows talking to targets using different I/O voltage levels (1.8V to 5V), but it's especially useful to avoid backpowering a target through the TX line.
This board can be assembled by JLCPCB PCBA for about $5 each, see the fab/ directory for Gerber/BOM/CPL data.
