Here, i will document my journey of creating cheapest Flipper Zero in the world.
Currently, i dont have NFC, And RFID, the rest do work.

I just dont like abstraction...
anyway...
Now, it seems to transmit on right frequncy, BUT, i need top calibrate my cheeap RTL-SDR, to be really sure...




SubGhz tests and optimization.
Today, s decided to test the SubGhz module on my (currently 15 USD) DIY Flipper zero.
As you can see, i find out, that transmision is happening on 433.88, instead of 433.92, and i believe, that it is caused by crysal on cheap chinesse module, so i decided to to find a way how to fix this in the FW.

Transmision on SDR

  • 1 × STM32WB55CGU6 similar, almost same MCU as Flipper use, but MUCH cheaper
  • 1 × TI CC1101 classic
  • 1 × 128x64 SPI LCD using ST7565R controller
  • 1 × MikroElektronika NFC 4 Click I believe, its most suitable for me.
