ATmega328PB ICSP/UART breakout
ATmega328PB has a second UART port that is sharing pins with ICSP/SPI. While this can be handy for debugging you may need to swap ICSP and UART dongles. This breakout board features:
- ICSP in connector, UART in connector
- ICSP out connector
- switches that enables/disables the shared pins in ICSP and UART ports
- switch to choose if the device should be powered from ICSP or UART
- reset button for the ATmega328PB
- (Optional) Power LED
This PCB is designed to be beginner friendly. All you need to populate are the through hole switches and 2.54mm headers. The button and SMD LED (0805) are optional - a great way to start with SMD components.
- 3x DPDT On-On 2.54mm pitch switch - i.e. https://lcsc.com/product-detail/Toggle-Switches_Korean-Hroparts-Elec-K3-2235D-F1_C189615.html
