Adafruit CP2102N Friend – USB to Serial Converter
Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the Adafruit CP2102N Friend!
The CP2102N is very similar to the CP2104. Despite having a name with a lower number, its actually considered the successor/next generation to the CP2104. Compared to the CP2104, the CP2102N can:
- Transfer data at a faster rate: CP2104 is 2Mbps max, the CP2102N is 3Mbps max
- Reprogram the internal settings: CP2104 has a one-time-programmable memory and the CP2102N has reprogrammable settings memory. 99% of people don’t use this capability but it is there if you need it.
- The CP2102N improves over the CP2012 (no N) by having the same RS-485 and GPIO support that the CP2104 has
- More details in the SiLabs CP2104 to CP2102N migration guide.
We’ve also updated this breakout from our CP2104 Friend so that it has USB C instead of Micro B. It is otherwise ‘drop in compatible’ and anywhere you would use the CP2104 for uploading firmware to microcontrollers, it’ll work exactly the same.
