## Serial Connection
**New** Shelly 2.5 model comes with a partially exposed programming/debug header which can be used to flash Tasmota on the device. A USB-to-UART adapter is needed as well as a reliable 3.3V with at least 350 mA drive capability. The following diagram shows the device pinout and power source voltage selection jumper. Onboard connector is 1,27mm raster with 1mm diameter holes so normal dupont cables won't fit. Use stripped ethernet cable and breadboard as adapter to avoid damaging the pcb.

The legs of female header sockets fit nicely. Solder them to custom-crimped dupont wires for use with your USB-to-UART adapter. These often come with Wemos D1 Mini boards in mutliple lengths:
