These prototyping boards come in handy for various reasons. comes with Bluetooth, Wi-Fi and RS 232 built on board. You can use it to interface with the multitude of various applications or hardware protocols.

I recently started tinkering with Arduino based projects and think I have found myself a new hobby. While you do need a decent stockpile of parts for the various projects, these are sort of required. I have a small animal problem and wanted a more discreet method of solving it. So rather than being activated by motion or sound, I opted for a wireless option that can be activated by sending a signal. I am using these specifically for activating ultrasonic frequencies and have worked seamlessly. As mentioned, you do need a variety of parts to make all of these things work, including power supplies. But nothing a small solar panel and rechargeable battery pack can't solve. My only 'small' obstacle was making it all waterproof. So a little hot glue and tupperware served well for outdoor, weatherproof applications.

Hey, it's 3x ESP-32s for just a few dollars, and in every way that I can find they seem to function normally. I hooked them up as ESPHome devices in Home Assistant and they had no issues doing the initial connection via USB and then an OTA when I pushed firmware updates to them. Great to have them around for hacking on smart home projects.

Good boards! I ran blink on all of these with no issue. The plan is to integrate them into my ecosystem with HA/ESPHome and/or WLED. These are the NodeMCU dev board design, so the pin width is narrower than you might expect if you have a breakout specifically for that pin width (although my breakouts have multiple spacings to accomodate the different ESP32 designs). That means they are, however, breadboardable unlike wider ESP32s, which is a feature I REALLY like.

Visually the board is very clean, no processing residues. The laser etching on chip is clear, and matches what is shown in the listing. The silkscreen was also impressive, crystal clear. The pin labels are on the bottom of the chip.Flashed a typical esphome config for a few sensors and blue tooth presence sensing-- I've had it up and running for a few days with no problems. Wifi, serial, network, rtc, and watchdog all good.And the boards were sealed in, what i hope is a more environmentally friendly wrap than typical static shielding bag. And the "Not to be handled by unauthorized personnel" label made me feel cool and special.Thanks for reading, and the opportunity to review this item. These are nice clean boards that I've had no issues with. I'd be willing to pay slightly more than average for these esp32 boards.
