MakerFocus ESP32 Development Board WiFi with 0.96inch OLED Display WIFI Kit32 Arduino Compatible CP2012 for Arduino Nodemcu

Q: How do i connect to arduino ide? i can't figure it out from the referenced web site

This Heltec board differs somewhat from other ESP32 boards with an OLED display I have used. For example, programs that work with the Wemos Lolin32, I've had to edit the display() constructor as follows: "SSD1306 display(0x3c, 4, 15):". Also you must reset the OLED display in setup() with the following code: "pinMode(16,OUTPUT); digitalWrite(16, LOW); delay(50); digitalWrite(16, HIGH);". You can see an example of this in the file "Heltec-Aaron-Lee/WiFi_Kit_series/esp32/libraries/OLED/examples/SSD1306SimpleDemo/SSD1306SimpleDemo.ino" on github.com.

Q: Does the display use i2c or other?

It uses I2C. CLOCK = 15, DATA = 4, RESET = 16 If you are using the U8G2 library, the line you want for software rendering is "U8G2_SSD1306_128X64_NONAME_F_SW_I2C g_OLED(U8G2_R2, CLOCK, DATA, RESET)" For hardware rendering, the order of the pins changes "U8G2_SSD1306_128X64_NONAME_F_HW_I2C g_OLED(U8G2_R2, RESET, CLOCK, DATA)"

Q: Is this preflashed? some heltec esps will boot when powered via usb outa the box, this doesn't seem to.

Mine did but I reflashed it right away with my own program

Q: Is there a breakout board with terminal blocks this fits in? Doesn't seem to fit those made for devkit c.

I think I just plugged ribbon header cables into it to test.
