Why it's different

Internal oscillator

Stable frequency without external crystal or SAW resonator.

No diodes

Up to 6-key matrix without 1N4148 or BAV70 — simpler board.

Ready to use

No production programming required; adjustable +13 dBm.

✕ Conventional solution requires

Cristal SMD 3225 (XTAL)
Ressonador SAW SMD
2× diodo 1N4148 (MiniMELF)
Diodo duplo BAV70 (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
