◢ Our creation
RF integrated circuits at 433.92 MHz for remotes, alarms, and access control — no crystal, no SAW, no diodes. From Engeletron, Brazilian engineering.
Stable frequency without external crystal or SAW resonator.
Up to 6-key matrix without LL4148 or BAV70 — simpler board.
No production programming required; adjustable +13 dBm.
Engeletron does not merely use chips — we design the integrated circuit. The EETX433A originates as a die on a silicon wafer, manufactured and diced into thousands of units, packaged in SOIC‑8.
Brazil — EngeletronThe concept, RF architecture, and design/IP of the EETX433A are ours, created in Brazil.
Partners — ChinaWafer production and packaging are carried out by partner foundries in China, which bring together the equipment, expertise, and cost structure needed to manufacture at quality scale.
Fabless model, with full transparency: the design and IP of the EETX433A belong to Engeletron; manufacturing is handled by partners with the infrastructure to do it — the same way the world's largest chip companies operate.
