ESP32

7/24/2021 I bought this from Amazon; (?Heltec?)HiLetgo ESP32 OLED WiFi Kit ESP-32 0.96 Inch Blue OLED Display WiFi+Bluetooth CP2012 Internet Development Board for Arduino ESP8266 NodeMCU a long time ago, it's been in a box for a couple years. I thought I'd give it a whirl. from the tasmota 9.5.0 releases page I've loaded tasmota32.bin, it currently has tasmota32-display.bin. It connects, I configured GPIO25 as relay allowing me to toggle an onboard LED.
