Configuration
{"NAME":"TTGO-0.91","GPIO":[1,1,640,1,1024,0,0,0,1,1,608,1,0,1],"FLAG":0,"BASE":18}Careful not to confuse this device with the Heltec WiFi Kit 8. The markings are identical but the GPIO assignments are different for the OLED. Heltec is a white circuit board with rounded edges. This one is black, has sharp edges and a prominent TTGO label at the top.
