SmartEVSE has a CLI available via a FTDI/UART/TTL interface.
To use the CLI you needa USB to TTL cable, a TTL-232R-3V3 would work. But a 5V cable also works.
The pin layout on the board (underneath the LCD) is:
- Ground
- Unused
- Unused
- RXD
- TXD
- Unused
In your terminal use these settings:
- 115200 8N1
- No hardware of software flow control
Hit enter a couple of times and you should get a menu.
