Nokia 5110 – Back from the Dead (2022)

I loved my Nokia 5110 and I wonder if it was possible to breathe new life into this long-shelved and still-memed mobile phone. As it turns out, not only is it possible, but it's going to be a lot easier than I anticipated.

The overview sourced from the SIM7600 hardware design documentNow armed with this chip, my next mission was to disassemble a Nokia 5110 and see how much effort would be required to retrofit this phone. Such a simple and elegant design nowadays, but revolutionary for its time.To by absolute suprise and delight, the construction of the 5110 has meant that this project is going to be decidedly easier than I originally hoped, and will allow me to maintain the entirety of the look and feel of the 5110 while giving it new life as a 4G phone. Thanks to Nokias design skills, i will simply be able to recreate the baseboard with the new 4G module, a microcontroller, and some audio processing and power management circuitry and it will be able to seamlessly fit inside the phone.
