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?** A: 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.** A: 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.** A: I think I just plugged ribbon header cables into it to test. ## Frequently Bought Together - MakerFocus ESP32 OLED WiFi Kit V3 Integrated WiFi Bluetooth 2.4GHz PCB Antenna CP2102 Development Board with 0.96-inch OLED Display for Arduino Intelligent Scenes - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA Compatible with Arduino IDE (3PCS) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/49779937-esp32-oled-wifi-kit-v3-integrated-wifi-bluetooth-cp2102-iot](https://www.desertcart.kr/products/49779937-esp32-oled-wifi-kit-v3-integrated-wifi-bluetooth-cp2102-iot) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-18*
