USB to UART Expansion Card for the Framework Laptop
Currently an early version, design untested
A USB to UART converter based on the CP2102 chip by Silicon Labs, also includes an external 3.3V LDO for more power than the integrated on.
- almost no extended JLC SMT parts
- no FTDI parts
- at least 150 mA @ 3.3V
- Do cost optimization
- find a good LDO (AMS out of stock)
- fix some SMT data
Parts, PCB and Assembly at JLC PCB are about 24€ for 5 PCBs, 2 assembled.
Based on the reference design by the Framework Team. Not responsible for anything. Design provided as is.
