Modification OpenSprinkler 3.3 external antenna

• Only for new orders: We build your OpenSprinkler to a version with EXTERNAL ANTENNA CONNECTION.

We're replacing the CPU board with a version with an ESP-07S/SMA processor. This version has an external antenna connector (I-PEX) instead of an internal antenna.

To do this, we install an I-PEX to SMA cable, which we lead out to the Ethernet connection.

External antenna NOT included.

Connection: SMA

Wireless standard: 2.4GHz WiFi

Warranty note: All boards are tested after conversion. Any modifications (e.g., drilling holes, etc.) will void the warranty.
