- HiLetgo 2pcs ESP32-DevKitC ESP32-32U Core Board ESP32 ESP-32 ESP32U Development Board for Arduino

Works as expected

These little boards are helpful! However, this revision uses an Xtensa LX6 - which is a pain to get working compared to the RISC-V revisions. That's especially true for Rust users - RISC-V is fully supported after you run the single `rustup` installation command. However, Xtensa boards require an extensive setup, which is unsuitable for beginners. Afterward, you'll likely face weird, undocumented problems that leave you running scripts for hours. If you do end up with this version, there are limited online resources to assist you. The setup documentation isn't detailed, and some pages are contradictory... As such, I don't recommend this version of the board. Grab some fancy RISC-V revision - you won't regret it!

Great, and cheap, esp32’s. Usually you end up with a bad one in the bunch and I have ordered these several times and haven’t had any issues. It’s a good buy if your looking for an esp32!

I see a lot of folks having trouble connecting to or programming this little device. The solution is to follow instructions and a few simple troubleshooting steps. Step 1: Is the serial driver loaded? Probably not, go load it. (Google "CP210x Universal Windows Driver") Step 2: Did you select the right port and board in the IDE? "ESP32 Dev Module" is what worked for me. If you're not seeing the COM port, go back to step 1. While I haven't tested the range, I'm not expecting a mile range line of sight. It's a ~$8 microcontroller and you get what you pay for. If you want RANGE and PERFORMANCE, then expect to pay for it. This is a hobbyist's chip, it is not designed for engineering projects that actually require specifications to be met. Buy this to experiment and learn with or just for the fun of it, but don't buy it expecting top notch performance for the price. You will be disappointed with that expectation. If you expect it to just be a useful thing to learn with and maybe do something useful with, then your expectations are more in line with reality. :)

I purchased these HiLetgo ESP32-DevKitC boards specifically to use with WLED, an open-source WiFi LED strip controller software, for an outdoor WS2812B led light project. I'm glad to report that both boards worked flawlessly right out of the box. In my experience, when buying multipacks from other companies, it's common to get at least one or two non-functional units. But not with these - they were perfect and performed as expected. Using an external 2.4GHz 6dBi antenna (sold separately), I was able to place the unit about 10 feet away from my router, even through an exterior wall, without any connectivity issues.

An external antenna was the perfect solution for a security system project that needed to fit inside my legacy metal alarm system box.

I bought two , they Stopped after several times programming
