Review on πŸ”Œ KeeYees ESP-WROOM-32 Microcontroller Development Board with Dual Core WLAN WiFi + Bluetooth 2-in-1 - 2PCS Set for Arduino by Jerry King

Revainrating 3 out of 5

Some problems . for computers and accessories

1. Programming with Arduino requires the push of a button. Just get a modern model that doesn't need it.2. WiFi doesn't work out of the box. You need to place a hefty tantalum capacitor (5-10uF) between 3.3V and GND (last pins on 2 sides, opposite USB). Otherwise, the power surge from WIFI will reset the device immediately when WIFI is turned on. This is unacceptable. The capacitor must be on the board. There is indeed a tantalum cap on the board next to the 3.3V regulator, but that's probably too small (a cost-cutting measure?) Why sell a WIFI board when the WIFI doesn't work? But after you have done that (after struggling for hours you will find out) and after installing the USB driver and the development module you can create a simple WIFI web server. But rather spend a little more for a better module.

Pros
  • Quick-Change
Cons
  • Almost never
