Customer Reviews
Consistent quality as always
I ordered an ESP32 Development Board and some Jumper Wires. Shipping took about 6 days to get to my place in Ohio, which was fine. The items were packed well, no issues there. This is my third order from them and the quality for the price is still what I expect. It's why I keep coming back when I need parts for projects. Glad they're reliable.
Good value for my project parts
I needed a few things for a new project, specifically a DHT11 Temperature Sensor and a small OLED Display Module. I spent some time checking prices around. Quartz Components had a decent price, plus I got a new user offer which helped bring the total down a bit more. The shipping wasn't super quick, took almost a week, but everything arrived safely. For the cost, I think it was worth it. I'm always looking for a good deal so the savings made a difference.
Got my Raspberry Pi 4
So I finally got around to getting a Raspberry Pi 4 from here. Was a bit hesitant since they can be hard to find sometimes. It came quicker than I thought, maybe 5 days to reach Denver. Everything was in the box, looked legit. I also grabbed some Male Female Headers and a Power Adapter 12V 2A just to have spares. No issues with anything, it was a smooth process. Would probably order from them again if I need more stuff for another project, like maybe a different sensor or something.
