Kode Dot – An easy-to-use, pocket-sized, battery-powered ESP32-S3 devkit (Crowdfunding)

Kode Dot is a pocket-sized ESP32-S3 maker device for prototyping with a built-in 2.13-inch AMOLED, a 500mAh battery, a 9-axis IMU, a microphone and a speaker, an RTC, a few buttons, a GPIO header, and a magnetic connector for expansion. Kode Dot is designed to simplify the prototyping process. Users can still write code using the Arduino IDE, PlatformIO, or ESP-IDF framework and upload it via the kit’s USB-C port, but thanks to kodeOS firmware, each program becomes a standalone app with its own name, icon, and interface, accessible from the graphical user interface. Kode Dot specifications: SoC – Espressif Systems ESP32-S3 dual-core microcontroller with 2.4 GHz Wi-Fi, Bluetooth 5 LE, ESP-NOW peer-to-peer protocol System Memory – 8 MB octal PSRAM Storage 32 MB octal SPI flash microSD card slot Display – 2.13-inch Color AMOLED with 502 x 410 resolution Audio ICS-43434 MEMS microphone 1W MAX98357A speaker amp USB – […]

Waveshare has recently released the ESP32-S3 2.06-inch AMOLED Touch, an ESP32-S3-based watch devkit with Wi-Fi 4, Bluetooth 5, and offline voice recognition in a watch-style enclosure. We have written about various ESP32-S3-powered smartwatches in the past. Some examples include the TinyWatch S3 open-source device with various sensors, but no battery or a strap, and the more complete LILYGO’s T-Watch S3 with LoRa, audio, and a built-in battery. Compared to both of those, the Waveshare ESP32-S3 watch stands out with a 2.06-inch AMOLED capacitive touchscreen, a 6-axis IMU, two digital microphones, an ES8311 audio codec, an RTC (PCF85063), and AXP2101 PMIC with lithium battery support. The watch also features a microSD card slot, a USB Type-C port, programmable buttons, and reserved I2C/UART/USB headers for communications. ESP32-S3-Touch-AMOLED-2.06 specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 8MB PSRAM Wireless – […]

ESP32-S3 board features 1.91-inch AMOLED display and QMI8658 6-axis motion sensor

Waveshare has launched an ESP32-S3 1.91-inch AMOLED development board with a 6-axis motion sensor designed for the rapid prototyping of IoT and portable projects with interactive displays. The board is built around the ESP32-S3R8 chip, featuring a 32-bit LX7 dual-core processor running at up to 240MHz, with integrated 2.4GHz Wi-Fi and Bluetooth BLE 5. It also includes 16MB Flash, 8MB PSRAM, 512KB SRAM, and 384KB ROM for efficient processing and memory management. At the core of its display capabilities is a 1.91-inch AMOLED screen with a 240×536 resolution, supporting 16.7 million colors. Powered by the RM67162 controller and connected via the QSPI interface, the display is ideal for running GUI applications like LVGL. The board is available in both touch and non-touch versions, with the touch-enabled models using the FT3168 touch IC. Other features include a QMI8658 6-axis IMU, a microSD card slot, and a Lithium battery header. The ESP32-S3 […]

T-Display-S3-AMOLED-1.43 – A 1.43-inch round AMOLED touchscreen display with an ESP32-S3 wireless MCU

We’ve already seen a few ESP32-S3 boards with an AMOLED display and plenty with round displays such as SB Components’ Dual Roundy, LILYGO T-RGB ESP32-S3, MaTouch ESP32-S3 Rotary IPS display among others, but I had yet to see an ESP32-S3 board with a round AMOLED display. That’s just what the LILYGO T-Display-S3-AMOLED-1.43 has to offer. The ESP32-S3 board features a 1.43-inch round AMOLED with 466×466 resolution and a capacitive touchscreen, a microSD card slot for storage, an RTC with backup battery, two 14-pin headers and a Qwiic UART connector for expansion, a USB-C port for power/charging and programming, and a 2-pin connector for a LiPo battery.
