MCU: STM32L433 with USB and RTC Display: Round 1.28" TFT LCD display Rotary Encoder: 15 pulses / 30 detents NOR Flash: 128 Mbits Power: 3 V, 400 mA Connectivity: MicroUSB connector, adaptor board and cable for ST-LINK, and breakout pads for peripherals Milled Aluminum or 3D-printed body: CAD files will be available for custom prints Open source software: Can be programmed with STM32CubeIDE 1.6.1 or Arduino IDE Open hardware: Built with commonly available components for easy modification
There was no open source / open hardware encoder with display. The one that are available were more expensive with less capabilities.
RoEnDi hardware and software are open source, so you can modify and customize its components as you wish. We also worked to build RoEnDi with readily available off-the-shelf parts, so you can modify and repair your RoEnDi if you ever need to.
The encoder-and-displays MCU also contain a multitude of available IO pins to work with. They are broken out to pads on the side of the PCB so you can easily connect to the UART, CAN, I²C, PWM, DAC, and SAI peripherals. These interfaces can be used to communicate with a large variety of third-party ICs, including LED drivers, speakers, motors, and sensors that detect temperature, humidity, and light, to name just a few examples. One of the great things about the STM32L4 MCU is that all pins tolerate 5 V for easy interfacing.
RoEnDi can also be used in conjunction with other connected devices, such as Wi-Fi and Bluetooth modules, which makes RoEnDi great for wireless interfaces and IoT applications.
