Pre-Program Testing
Ok, by this stage you should now have your receiver board assembled, you've got your 9V "regulated" power supply and you have checked all of your solder joints under the magi-lamp and also cleaned the dry rosin from the PCB with some Isopropyl Alcohol and a clean tooth brush or similar.
Insert "just" the Mega2560 Pro Mini module (no other modules) and power up the receiver board with your plug-pack. I like to perform a few preliminary checks before I insert my active modules. Referring to the photo below which shows an easy GND point to use and all of the voltage spots on the board that we are going to check.
If all looks good in the tests above, you should be right to install your Baro module, RTC module, TX and RX modules. At this stage, since we are now installing the TX module, I like to always have 433MHz antenna fitted ( to the TX SMA connector) from this point forward whenever power is applied. This is always good "radio" practice and will avoid any chance of the TX module being damaged by not having any load to dump the power into.
