- the main processor, a 28 DIP ATmega328 chip is definitely fried! I do have the option to program a blank one or order one already programmed from QRP-Labs.
- The LCD display has been zapped.
- The relay on the main Ultimate 3S board has most likely been burnt out as well by the higher voltage.
- It’s supposed to be unlikely that the Si5351A Synth Module has been damaged.
- On the QLG1 GPS unit it’s probable that the 74ACT08 level converter chip has been destroyed by the high voltage because of the way the LED indicators are behaving when power is applied. Yellow is not pulsing once a second as it should…
This is such an unrare event that QRP Labs have created a product especially for people like me – the QCU QRP labs control unit which components most likely to need replacement after applying the wrong voltage! It includes the 16 x 2 LCD module, 20MHz crystal, BS170 transistor, buttons, resistors, capacitors, hardware and all connectors (4-way sockets, 10-way sockets, 16-way plug/socket for LCD) that are used in the Ultimate 3S kit.
