Re: Do not solder ground. Instructions mess

If you plan to use a speaker, it should be wired to the SPK1 header and use those two connections only. Do not try to attempt to ground the speaker to the negative terminal in common with the battery supply.? If you plan to use speaker and headphones together, you can wire the speaker to the supplied headphone jack. When a headphone is inserted, it will disconnect the speaker and route the audio through the headphones.? If you look on the schematic, there art two grounds. The audio circuit is on GNDREF. The RF circuit is on GND.? I don't know what the consequences would be if you mixed the two up. But I don't want to find out.?
