EMONGLCD not working

 Hi! All,

New to this forum and I would like to ask for some assistance on the assembly.

I have assembled the module and have the 3.3v output as requested on the Gnd and 3v points on the board. However, nothing is working.

Can any one advise?

Hi Robin,

Welcome to the forums! 

I believe Trystan has answered your email. The Atmega328 microcontroller is shipped blank. Nothing will happen until you upload some code. This can be done using the Arduino IDE and a USB to UART programming cable. We have some instructions here: http://openenergymonitor.org/emon/modules/emontx/firmware.

Best of luck,
