Review on HiLetgo ESP WROOM 32 Bluetooth Development Display by Joseph Winfrey

This little beauty is perfect for connecting to a server via WiFi to transmit sensor data or emulate a BT controller on something like a FireTV. I think the display strikes a good balance between having enough space to display a few crisp lines of text and being easy on the battery for the first 30 minutes of use. I'm still amazed that at this price you can get a microcomputer that allows you to use the espressif toolkit to put decent sized binaries into such a small package. No joke, you have enough power to emulate a CP/2 OS while using an NTSC video connection as a second display on an OLED! If you're looking for a small board to prototype your next project, you could do worse than this kid.
