  • 2x DS18B20 terminals available via terminal block.
  • 433/868Mhz RFM69CW (HopeRF) wireless transceiver to transmit/receive data to other OpenEnergyMonitor and JeeNode modules
  • Status LED

 

* with 9V AC adapter

 

Assembly of Non-SMT components

The board comes with all the SMT components the resistors, capacitors and LED already on the board. The non-smt components (the arduino headers, ftdi connector, CT and ACAC jack sockets) do not come pre-assembled and so a little soldering is still needed to complete the build of this board.

When assembling: The 3.5mm CT sockets and 2.1mm AC-AC Adapter socket needs to be soldered on the bottom of the PCB. This slightly unconventional design was chosen to make a low profile design possible.

See Technical Wiki page for info on RFM12B jumper settings, wiki page refers to the old 'thru-hole' design but the RFM12B operation and pin-out's have not changed.

 

EmonTx Arduino shield is not compatible with other Arduino shields that use I2C
