Vietnam 🇻🇳

Hi, I'm Thach — an embedded software engineer and the creator of TinyUSB, an open-source, cross-platform USB Host/Device stack for microcontrollers used by thousands of projects worldwide.

I also maintain and contribute to a wider set of embedded open-source projects in the Adafruit ecosystem, including Adafruit_TinyUSB_Arduino, tinyuf2, the Adafruit nRF52 Arduino core and others. Together, these projects power a huge range of hobbyist boards, commercial products, and educational hardware.

I'm doing this from home with young twins underfoot 👶👶 — joyful and chaotic in equal measure. Your sponsorship directly helps me carve out the time to keep these projects healthy: fixing bugs, reviewing PRs, supporting new chips, and adding features the community needs.

Whether you're an individual hobbyist whose project relies on TinyUSB, or a company shipping products built on top of it, every contribution helps sustain this work. Thank you for considering sponsoring — it genuinely makes a difference. 🙏

A steady base of monthly sponsors lets me keep TinyUSB healthy, ship new MCU ports, and stay responsive to the community. Every sponsor at every tier counts. Thank you! 🙏
