About us
We specialize in sourcing and supplying authentic STMicroelectronics components—STM32 microcontrollers, EEPROMs, analog ICs, and more. Every item is carefully inspected and shipped in shielded or secure packaging to ensure quality and reliability.
Though small in scale, we’re fast, agile, and focused. We respond quickly to individual needs and value trust over volume. Our core is STMicro, but we’re open to sourcing other semiconductors when possible.
Let’s build a reliable connection—built on speed, precision, and transparency.
