ESP32-S3 based 1.28-inch round touchscreen display supports Arduino programming

ESP32-S3 Round Display 1.28-inch touchscreen

Makerfabs “ESP32-S3 Round SPI TFT with Touch 1.28″ is a small ESP32-S3 with a 1.28-inch round color touchscreen display, a microSD card, support for USB and battery power, and two “Mabee” extension connectors. The board joins other ESP32-S3 round display boards such as the Lilygo T-RGB board or Seeed Studio’s Round Display for XIAO, but with a thinner design, and a square PCB with trimmed corners instead of a round PCB like the other two. ESP32-S3 Round SPI TFT with Touch 1.28″ (E32S3128GC) specifications: Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz with vector extension, 512KB SRAM, 8MB PSRAM, Wi-Fi 4 & Bluetooth 5.0 dual-mode (Classic + BLE) connectivity Flash – 128 Mbit (16MB) W25Q128JV SPI flash, microSD card slot Display – 1.28-inch round LCD with 240×240 resolution (GC9A01 SPI driver), touchscreen controller (CST816S) USB – 1x USB Type-C port Expansion 1x 4-pin Mabee I2C […]

PiEEG shield for Raspberry Pi enables brain computer interfaces (Crowdfunding)

PiEEG is an open-source hardware Raspberry Pi shield that measures electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG) bio-signals and provides a brain-computer interface to applications or robots for gaming, entertainment, sports, health, etc… Ildar Rakhmatulin, a Research Associate at Heriot-Watt University in Edinburgh, is passionate about open-source brain-computer interfaces and first created the IronBCI project based on ADS1299 and STM32 and published a research paper entitled “Low-cost brain computer interface for everyday use” about his work. But cost increases related to the semiconductors shortage of recent years meant the price for his “low-cost” project shot up to over $1,000. So he went back to the drawing board and created the PiEEG shield for Raspberry Pi now available on Crowd Supply. PiEEG shield specifications: ADC – Texas Instruments ADS1299 Analog-to-Digital Converter for biopotential measurements Supported SBCs – Raspberry Pi 3 or 4, and boards with the same 40-pin GPIO header. Host […]

Pocket AI – A portable NVIDIA RTX A500 eGPU for AI developers, embedded & industrial applications

We’ve previously seen it’s possible to connect an eGPU to a mini PC through a PCIe x16 to M.2 NVMe adapter or a Thunderbolt 3 port, but while it’s fine to install on your desk for gaming or develop AI applications, the eGPU being larger than most mini PCs, it’s a little too big to integrate into products, and potentially inconvenient to carry around. ADLINK Pocket AI portable eGPU changes that with an NVIDIA RTX A500 GPU housed in a 106 x 72 x 25mm box that’s about the size of a typical power bank and connects to a host through a Thunderbolt 3 connector. The company says the upcoming eGPU is mostly designed for AI developers, professional graphics users, and embedded industrial applications, but can also be for gaming. Pocket AI specifications: GPU – NVIDIA RTX 500 Architecture – NVIDIA Ampere GA107 Base clock: 435 MHz Boost clock: 1335 […]

NanoPi R6C review – Ubuntu 22.04, NVMe SSD, USB debug

FriendlyElec has recently announced the NanoPi R6C mini PC that a variant of the Rockchip RK3588S powered NanoPi R6S mini PC and 2.5GbE router that we reviewed with FriendlyWrt/OpenWrt and Ubuntu 22.04 earlier this year, but with just one 2.5GbE and one GbE interface, a built-in M.2 NVMe SSD socket and USB-C Debug UART port for easy external access to the serial console. The company sent me a NanoPi R6C sample for review, but since we’ve already tested the similar NanoPi R6S extensively, I’ll write a single-post mini review this time around, checking out the hardware, and focusing on testing the new features such as the NVMe SSD and the USB debug port when running Ubuntu 22.04. NanoPi R6C unboxing As usual, the device came in a non-descript cardboard package with a few 3M rubber pads. The most obvious change compared to the NanoPi R6S is that all main ports […]
