Prewired 16x2 blue display
...or more specifically,
or an upgrade if you like, As to soldering pins to the board, I might suggest first tinning the pins alone; if you have some soldering flux, a trace amount on the circuit board holes won't hurt though optional. Then, with the board held by a vise or similar, use pliers to hold the pin and place it about 3 or 4mm (1/16"?) into the hole. With a small drop of solder on your iron's tip, heat only the tip of the pin until the solder wicks onto it. Then, immediately draw the pin and the iron outward together to a suitable mounting position for the pin. You can and should roll the hot iron tip around to touch the circuit board, at which time the solder will wick over to the circuit trace. REMOVE HEAT as soon as the wick happens.? Blow on it, cool it, etc and you will be OK from there to continue to the next one. Hint: Not all pins are used or necessary. Ted K3RTA |
It seems the problem is mainly about soldering technique or general electrical repair.
One tip I have is to plug the female connector on to the male connector. Use quality solder and additional flux. along with a clean tip.? Solder a pin near each end then move around so you don't heat them in kind. A bit like tightening lug nuts on a wheel.? -- 73 Dave k0mbt |

Is there a larger 2 line display we could substitute directly for visually impaired or for mobile use thats easier to see??Yes there are somewhat larger common 16x2 displays. I can't speak to 'direct' replacement, (not interested in doing that homework) but these have I2C modules and 6800 parallel library support. Look at the datasheet and see if the size is what your after.? The rest should be simple software changes, if needed at all.? |

I have bought two of those displays from them, and neither worked. The larger displays I have (5 from different sources) do not use the same pin out as the regular ones. The last two pins are reversed, and if you power on wired wrong it will destroy the display.? Mike AI4NS?
