2. Requirements

Roc-MQTT-Display

Hardware

• 1x Microcontroller, tested with:
  - Lolin D32
  - Lolin D32 Pro
  - Lolin/Wemos D1 mini (4MB flash memory)
  - Lolin/Wemos D1 mini pro (16MB)
  - D1 mini Clone with min. 4MB
• 1x I2C Multiplexer TCA9548A, only required if you want to run more than 1 display per controller
• 1-8 OLED I2C Displays, tested with:
