CP2104 atmega32u4 Wiring

Post by P123 » Wed Apr 12, 2017 11:33 am

Hi I have the CP2104 and atmega32u4 board, identical to one in shop.

Will following wiring be correct or should it be inverted?

CP2104 - atmega32u4

TXD - TX0
RXD - RX1
GND - GND

All three are next to each on both boards. Is there any wire that can be used as female to male, so I can solder directly to atmega32u4 or is it best to use the female to female jumper wires and solder the pins that came with the atmega32u4?

Hi,

GND goes to GND, and TX on one board goes to RX on the other board.
You can use female to male jumper wire. It's easy to find on ebay or aliexpress.
