In this post, we will look at how to interface and display data on a 0.96-inch 128x64 SSD1315 I2C OLED display using ESP32-C5_MINI and MicroPython. For these exercises, we will use the official micropython-ssd1306 driver. Because the SSD1315 shares the exact same command structure for basic operations as the classic SSD1306, this library works flawlessly out of the box. Getting the Library There are two easy ways to install the driver on your board: Via Thonny IDE: Go to Tools ➔ Manage packages..., search for micropython-ssd1306, and click Install. Manual Installation: Download ssd1306.py directly from the official MicroPython-lib repository and save it onto your ESP32-C5 file system. Connection SDA - IO3 SCL - IO4 VCC - 3V3 GND - GND Exercise Code mpy_C5_ssd1306.py , basic setup and test.

This post walks you through the step-by-step process of flashing MicroPython firmware onto the ESP32-C5_MINI . 1. Download the MicroPython Firmware First, grab the correct binary for your chip: Visit the official MicroPython Download Page . Search or scroll down to the ESP32 section and locate the ESP32-C5 targets. Select ESP32-C5 by Espressif and download your preferred .bin file version. 2. Flash the Firmware (The 0x2000 Offset) To flash the firmware, connect your board to your computer and run the following esptool command. ⚠️ Crucial Note: Unlike older ESP32 chips (like the S3) which often start flashing at 0x0 , the ESP32-C5 requires you to write the flash starting exactly at address 0x2000 . Run this command in your terminal (replace PORTNAME and the .bin filename with your actual values): esptool --port PORTNAME ...
