IDM2040-21R is a 2.1-inch Rotary Dial Display, which was designed using Raspberry Pi RP2040 microcontroller with FT800Q, a rotary encoder with button, RS-485 transceiver and a 2.1-inch round LCD.
The host MCU RP2040 is a microcontroller unit (MCU) developed by Raspberry Pi, Dual ARM 32-bit Cortex-M0+ Core processors running at up to 133 MHz, 264KB of SRAM, and 8MB of on-board Flash memory.
Main Features:
- 2.1-inch Round LCD Screen: 480x480 resolution with capacitive touch support
- 1 x I2C: Inter-Integrated Circuit for connecting multiple peripherals
- 1 x UART: Universal Asynchronous Receiver-Transmitter for serial communication
- 1 x RS-485: for long distance and reliable communication with other devices
- 1 x Audio Output: for audio applications
- RGB666 hardware interface for high-quality color display
- Rotary Encoder: 24 steps with a push button for input and control
