Another Kingston winner
Worked as designed

Excellent value for IoT experimentation.
Testing this development board as a plug-in replacement for a more expensive one on Amazon. This one isn't finished as well, and has cheaper silkscreening on the pin side, but that did not matter too much. Also, no schematic (the Amazon one has the schematic). There are several Internet PDFs from hobbyists who have nice overlays to work with the device with a breadboard, since you cannot see the silk-screening.
Initially, I could not program the device with my Linux espressif toolchain, as the device was in constant reset (SPI_FAST_FLASH_BOOT) after a program was downloaded into it. After a while, I decided to run a simple "blinker" sketch from the Arduino environment (NodeMCU32S) and was successful, as was a more complex sketch that employed the onboard http server. No issues. So I went back to my espressif environment , and this time, the device "took the programming" and worked just like the Amazon one. I'm using it with a Passive IR sensor, a few LEDs and a high torque servo.
These are great boards, and I plan to buy a couple more of these as my home automation experimental projects

Decent quality -- good value
Good adhesive. I put some solid metal fittings in there and they always make it to my customers.
