The Nokia 1680 receives a new PCB with MIPS SoC, running Linux main

Reimu NotMoe designed the “Notkia” PCB based on the Ingenic X1000E MIPS processor with a built-in 64MB of RAM and exactly the same size as the PCB found in Nokia 168x (1680, 1681, 1682) phones and allowing the phone to run on the main line. Linux.

The card also comes with a 32 MB NOR flash, a 4 GB SLC NAND flash and supports LoRa connectivity, 2.4 GHz WiFi, Bluetooth and GNSS, but without a cellular modem. The original design was

Notkia Nokia 168x MIPS Linux

Combining Nokia 168x with Notkia PCBA creates a phone with the following specifications:

  • SoC - Ingenic X1000E single-core XBurst MIPS processor at 1.0 GHz (2200+ CoreMark) with 64 MB RAM
  • Storage - 32MB NOR flash + 4GB SLC NAND flash
  • Screen - 2.0-inch 240 × 320, 3/4-inch IPS LCD visible (Replaces the original 128 × 160 TFT screen in the phone)
  • 5 MP autofocus camera (only available in the Nokia 1680 case)
  • Audio - Yamaha MA-3 Music Synthesizer (YMU762) and Regular I2S PCM Codec
  • Wireless connectivity - LoRa, 2.4 GHz WiFi, Bluetooth and GPS + GLONASS.
  • USB - 1x Type C USB port
  • Miscellaneous - RGB LED, temperature and humidity sensor
  • Power Management - BL-5C battery, Texas Instruments battery management solution
  • Dimensions - Nokia 168x shape

The Ingenic processor was selected for its low power consumption (0.3 W running the CoreMark standard), slightly better performance than a Raspberry Pi Zero, mainstream Linux support, and built-in RAM to save space on the PCB. and publicly available data sheets. The Notkia phone can be seen in action with demonstrations Bad Apple animation and LVGL music playerbut more software is needed and an LVGL-based desktop environment seems to be in the works.

A project log can be found on Hackaday.io, and the design will eventually be made open-source under the CERN-OHL2-S license, but only after a future Crowd Supply campaign is completed. Some early prototypes with Notkia PCBs alone should be available in advance. It will be a challenge to find the Nokia 1680 case to house the PCB in the future, but the related patents are scheduled to expire on June 23, 2023, when it will become legal to make cases with this design.
