Roundy is a round display with a Raspberry Pi or ESP8266 substructure that is fun to use. The displays should be able to be used for your own projects and come with a microSD card reader or WiFi.
The RoundyPi and RoundyFi are designed for makers who want to play around with a round display and have a developer board on hand. A 1.28-inch LCD screen is included in both model variants. A GC9A01 chip is used as the display driver, which is connected to the respective developer boards via SPI. The resolution is 240 x 240 pixels, 65,000 colours should be displayed.
The RoundyPi is powered by the RP2040 microprocessor and has a microSD card slot. This makes transferring visual material to the tablet very simple. Four GPIO pins can be used to link external sensors and actuators.
The Model RoundyFi is built on an ESP-12E chip and may also use four GPIO pins; the model version should be chosen based on whether or not previous expertise with the RP2040 is available, and whether or not a WiFi connection is required.
The RP2040 has two Cortex-M0+ fast cores running at up to 133 MHz and a 256 kilobyte RAM, while the EPS-12E has an ESP8266 microcontroller running at up to 160 MHz, 160 kilobytes of SRAM, and a four megabyte flash memory. The ESP chip, unlike the RP2040, supports WiFi.
The RoundyPi is currently available for pre-order as part of a Kickstarter campaign for the equivalent of roughly 24 euros, with the RoundyFi costing six euros more. The first deliveries are expected to begin in April. As is always the case, there is no guarantee that the project will be completed successfully.
