Review on HiLetgo ESP WROOM 32 Bluetooth Development Display by Trey Harvey

This little beauty is perfect for connecting to a server via WiFi to transmit sensor data or a BT to emulate controllers. on something like FireTV. I think the display strikes a good balance between enough space to display a few crisp lines of text and not draining the battery for the first 30 minutes of use. I'm still amazed that at this price point you can get a microcomputer that will drive the espressif toolkit to cram decently 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.
