Reflashing the jn-esp's esp8266 itself (as opposed to the attached uController):
_you should not need to do this!_, in general use the over-the-air reflashing by downloading the latest release.
If you cannot reflash over-the-air and need to reflash serially, there are SMD pads for an FTDI connector on the
bottom of the PCB below the esp-03 module. GND is marked. The best is to solder a right-angle
connector to it such that the pins point up (i.e. to the component side). You can then
hook-up a USB-BUB. I recommend jumpering the flash pin (next to GND) to GND and to
hook the reset pin (6) to the USB-BUB's DTR (should happen automatically). RX&TX also go
