README.mdPMod Type 4A UART to USB interface using SiLabs CP2104
This is a board compatible with Digilent's PMod standard which allows you to interface a computer to FPGA via a USB UART.
It uses a SiLabs CP2104 for the USB to UART IC.
Features
It has;
- Plenty of LEDs so you can understand the status of the board easily,
- Good silkscreen so you don't need the documentation,
- Open Source Hardware,
IO Level and Power
The device can either; a) Provide 3.3V power supply from the onboard regulator to the Pmod VCC, b) Use the Pmod VCC for the IO level standard,
This means it can be used with many voltage levels other than the standard 3V3 normally used by PMod devices. The CP2104 supports VIO levels down to 1.8V
PMod Type 4A UART
This board follows the PMod Type 4A UART standard.
It should be a drop in replacement for the PModUSBUART while adding support for the extra signals in the PMod Type 4A UART.

Questions
How big is the Pmod cp2104 PCB?
It measures 67.9 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pmod cp2104 use?
41 parts, built around the CP2104EK. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pmod cp2104 KiCad files?
From the mithro/pmod-cp2104 repository on GitHub, at the commit this page was made from: the board is pmod-cp2104.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pmod cp2104 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
