Love CircuitSage! Their ESP32 starter kit came with clear instructions and the code worked first try. Fast shipping and the support team helped me debug a wiring issue. Will buy again for my next smart lamp project.

CircuitSage helped me build a home sensor network. The sensors were accurate and stable. I followed their step-by-step guide and used their example code. Shipping was quick and packaging was tidy. As a teacher, I’ll recommend these kits to my students.

I bought a wifi module for a remote camera project. CircuitSage provided clear wiring diagrams and example sketch. It connected on first boot and ran stable for weeks. The part quality is noticeably good compared to cheaper stores. I appreciate the attention to testing and friendly returns policy.
