TouchEye dual round touch display module features Raspberry Pi RP2040 or ESP32-S3 MCU (Crowdfunding)

TouchEye ESP32-S3 or RP2040 dual touch display board

Last December, Debashis wrote about the Waveshare Double Eye LCD module comprised of two round displays that can be useful for robotics or art projects since they can be made to look like googly eyes. The module is designed to be connected to a host MCU via an SPI interface. The TouchEye looks similar but offers larger 1.28-inch round displays (instead of 0.71-inch), and also adds a touch function. Instead of being connected to a host MCU via SPI like the Waveshare model, the TouchEye dual touch display module is a complete board with an onboard MCU that can be either a Raspberry Pi RP2040 or an Espressif ESP32-S3 that also offers WiFi and Bluetooth connectivity. Both boards also feature a USB-C port for power and programming, a microSD card slot, a GPIO breakout connector, and programmable buttons. TouchEye module specifications: MCU (one or the other) Raspberry Pi RP2040 dual-core […]

QuadClock PCB – An ESP32-S3 multi-display clock controller for DIY enthusiasts

The QuadClock PCB is an ESP32-S3-powered multi-display clock controller designed to serve as a foundation for creating a four-TFT-display clock. It supports up to four 1.69-inch rectangular TFT displays (240×280) or four 1.28” round displays (240×240). It manages essential functions such as driving the displays and maintaining precise time, allowing you to focus on crafting a unique enclosure or integrating additional features. It is open-source and is powered by the ESP32-WROOM-1 module with up to 16MB flash and 2MB PSRAM. It supports independent brightness control for each mounted display via four MOSFETs and includes an onboard real-time clock with a backup battery for accurate timekeeping. The QuadClock PCB is designed for enthusiasts and makers interested in creating multi-display clock projects. It can also be used for stock tickers, weather displays, and smart home dashboards. We previously covered the 2×2 Quad Display board with either Raspberry Pi Pico W or ESP32-S3-WROOM-1 […]

MaTouch SmartKnob Assembled ESP32-based rotary knob with touchscreen display sells for $69

Makerfabs has recently released “MaTouch SmartKnob Assembled” based on the SmartKnob View open-source hardware design but enclosed in a plastic case. As a reminder, the SmartKnob View is an ESP32-S3-based DIY rotary knob built around a BLDC motor. With clever software and engineering, the motor is so configured that it can do software configurable detents, haptic feedback, magnetic encoder, and more. It also has a round LCD touchscreen, and USB-C, and features a convenient 3D enclosure that can also be attached to your wall with some sticky pull tabs. The SmartKnob View was a great concept, but its DIY nature made it difficult for many people to get their hands on one as it was never manufactured in quantities. The MaTouch SmartKnob Assembled solves this issue by building upon the original design and comes fully assembled for immediate use. The original module integrates a 240×240 round LCD and uses an […]

Adafruit’s PioMatter library adds HUB75 RGB LED Matrix support to the Raspberry Pi 5

The Raspberry Pi 5 brought a more powerful CPU and GPU and faster I/Os compared to the Raspberry Pi 4, as well as some incompatibilities. While the transition from a Raspberry Pi 4 to a Raspberry Pi 5 is usually painless for most applications, Adafruit notes that the ability to drive HUB75 RGB LED matrices was lost on the Raspberry Pi 5 which now relies on the Raspberry Pi RP1 peripheral control to drive GPIOs instead of the Broadcom processor directly controlling them. The company has now addressed that by using the PIO (Programmable I/O) block in the RP1 chip, yes that’s the same PIOs as found in the RP2040 or RP2350 microcontroller, to drive HUB75 RGB LED matrices from the Raspberry Pi 5, and their work can be found on the Adafruit-Blinka-Raspberry-Pi5-Piomatter repository on GitHub. The instructions to install the Adafruit Blinka Raspberry Pi 5 PioMatter library (or just […]
