NOTE: I prefer to use a serial programmer verus OTA. That is me.
Hardware required.
1 - USB to Serial programmer - purchased an el cheapo programmer on Amazon.
With this device you will be using the RXD, TXD, GND and 3V3 pins. Note that mostly they are all the same.
2 - RPi with SSH access - doesn't matter what version of OS you have on it.
3 - device you are programming with pins or wires soldered on to the RX, TX, Ground and VCC pins
NOTE: if you are not comfortable with soldering then this method is not for you.
NOTE 2: DO NOT PLUG DEVICE in to an 120VAC outlet
