Why it's different
◷

Internal oscillator

Stable frequency without external crystal or SAW resonator.

⌗

No diodes

Up to 6-key matrix without LL4148 or BAV70 — simpler board.

⚡

Ready to use

No production programming required; adjustable +13 dBm.

✕ Conventional solution requires

✕ SMD 3225 crystal (XTAL)
✕ SMD SAW resonator
✕ 2× LL4148 diode (MiniMELF)
✕ BAV70 dual diode (SOT‑23)

✓ With the EETX433A

✓ Internal oscillator — no crystal and no SAW
✓ Up to 6-key matrix — no diodes
✓ Ready to use — no programming
✓ Fewer BOM items · smaller board · lower cost
