Review – ESP32 OLED WiFi Kit

A test of the HiLetgo Heltec ESP32 unit, with built in 0.96″ OLED screen.

ESP32’s are about the strongest performing WiFi microcontrollers of such a size and well suited for Internet Of Things projects.
The addition of a screen onboard really helps for configuring, diagnostics and other visual outputs.
