Conversion to OpenSprinkler 3.3 external antenna

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

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

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

External antenna NOT included.

Connection: SMA

Radio standard: 2.4GHz WiFi

Note on the guarantee: All boards are tested after conversion. Independent modifications (e.g. drilling or similar) will result in the loss of the guarantee and warranty.
