  • MTK-based phone or development module (with accessible debug/test points).
  • USB-to-Serial adapter (FTDI or CP210x) for UART access.
  • Stable DC power supply (adjustable, current-limited, 0–5 V, up to several amps).
  • Multimeter and oscilloscope (for power, clock, and signal verification).
  • Test SIM(s), preferably with prepaid plans for safe testing.
  • RF attenuator(s) and shielded test enclosure (Faraday cage) for over-the-air experiments and to avoid interfering with public networks.
  • GSM base station emulator or network simulator (optional but recommended): allows closed-network tests without affecting carriers.
  • High-quality micro-soldering kit and hot air station.
  • Heat-blocker and ESD protection (wrist strap, mat).
  • Smartphone or IoT development boards utilizing MediaTek chipsets (e.g., MT6735, MT6753, MT6580, or Dimensity series with GSM fallback).
  • Device must be configured with Meta Mode or Engineering Boot capabilities enabled.
