Board Size: 23.8x13.7x1.6mm
Soldered module size: 31.7x13.7x6.4mm
Connectors: USB-C to male 2.54mm dupont headers
Max current supply:
- without regulator: 50mA @ 3.3V
- with regulator: 1A @ 3.3V (often limited by USB supply)
- Added J1 Jumper that can be connected in order to use internal regulator.
- Switched RX and TX label on LEDs. Now the are labelled from the computer's (USB) perspective, which feels more natural to me.

- Not sure, however TX ad RX labels might be switched around. According the the datasheet it should be correct. (update: done)
- No easy way to disconnect internal regulator from external one without scratching out a copper trace which is difficult to do. (update: done)
- Add zero ohm resistor to switch between using the built in regulator or the external one. (update: done)
- Perhaps add power indicator LED?
- Different color RX and TX?
- Find part number of correctly angled dupont connectors.
- Design and print a case (Not something I have a use for, so I won't do this)
- Might want to add USB ESD protection?
The chip selection of FT230XQ-R is not the cheapest option, but it is a nice reliable chip, and has a very small footprint. I am open to and looking for cheaper alternatives to reduce cost of this device.
