Mainboard replacement for Nokia 3310//3330

This replacement board for Nokia 3310/3330 phones brings FM/FSK capabilities on 70cm amateur radio band (including 433MHz ISM). The board uses a G-NiceRF SA868S UHF RF module running OpenRTX firmware. Sample firmware for the MCU provides M17 messaging support with T9 text entry method. The device can be powered with original Nokia lithium-ion batteries or their replacements and is able to charge them through the USB-C port. A UART USB interface is available, allowing the device to work as an RF modem.

The design is open source and available for free on GitHub.
