(Yet another) Raduino replacement board

Jim W0EB has produced (yet another) drop-in Raduino clone, available in kit form, for anyone needing a replacement for a damaged Raduino that they are otherwise unable to repair or if they are just wanting to have a spare on hand.

It’s being offered as a bare board, a complete kit of parts INCLUDING the NANO which will be pre-programmed with Ashhar Farhan’s latest factory software from Github (Currently v4.3) or, for a slightly higher price, the kit version is being offered with the Si5351 already soldered in place and continuity checked to insure the connections are good and there are no shorts between the pins.

The new card has some extra bypassing capacitors.  The 4.7K CW pull up resistor can be directly mounted on the board (or if you are replacing an existing Raduino installation and have already wired it to your key jack you can leave it off the board).

The 7805 regulator has been mounted flat on the rear of the board with a heat sink and input dropping resistor so that it runs much cooler.

The clone is just over a centimeter wider than the original, but the display mounting holes have been kept to the exact same pattern.  A standard 16 X 2 parallel display will mount properly.  The display is not supplied with the kit to keep the cost lower as most users already have one or more on hand anyway.

The pre-programmed NANO  will be supplied with the pins loose and not installed so the user can mount it either on the front (not recommended) or on the back of the card to keep it out of the way of the display in the manner of the current factory supplied Raduino cards.

Any software that currently runs on an original Raduino will run on this card including the KD8CEC versions.  (That includes CEC’s Nextion enabled versions as well).

The construction manual, pictures of the board and ordering/availability information can be found on Jim’s website.
