* Note
- using Power from USB to Serial is may unstable, they not deliver enough current.
#### Serial Adapter ####
There are many different USB to Serial adapters / boards.
* Note
- for full upload management you need RTS and DTR
- the chip need to have 3V3 TTL (5V may damage the chip)
- not all board have all pins of the ICs as breakout (check before order)
- CTS and DSR are not useful for upload (they are Inputs)
* Working ICs
- FT232RL
- CP2102
- may others (drop a comment)
