TTGO LoRa32-OLED V1.0 pin assignments map LoRa SPI pins (SCK, MISO, MOSI, CS/NSS/SS, RST, DIO0) and OLED I2C pins (SDA, SCL, RST) to specific ESP32 GPIOs. Cross-checking these assignments prevents hardware miswiring and ensures correct board setup.

Verifying DIO0 pin mapping on the TTGO LoRa32-OLED involves checking the reference notes for its RTC-capable behavior. This ensures the SX1276/SX1278 DIO0 pin is correctly assigned in your project_config for reliable LoRa interrupts.

This pin mapping guide specifically targets the TTGO LoRa32-OLED V1.0 variant. Different TTGO board versions may have alternate SPI and I2C pin assignments, so you should cross-check against the specific reference mapping for your exact hardware variant.

Configuring project_config.h requires applying the ready-to-use reference mapping for the TTGO LoRa32-OLED V1.0. You define the correct ESP32 GPIO numbers for SX1276/SX1278 SPI and SSD1306 I2C interfaces to establish functional LoRa and OLED wiring.

TTGO LoRa32-OLED V1.0 hardware dysfunction often stems from incorrect SPI or I2C pin assignments. Verifying your SCK, MISO, MOSI, CS, RST, SDA, and SCL wiring against a verified reference mapping resolves these misconfiguration issues.
