◢ Technology
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
