T-Dongle-S3 USB dongle combines ESP32-S3 wireless MCU with optional color display

LilyGO T-Dongle-S3 is a USB dongle based on ESP32-S3 dual-core microcontroller with WiFi 4 and Bluetooth 5.0 connectivity, a microSD card slot, as well as an optional 0.96-inch color display. You may remember the company launched the T-Dongle ESP32-S2 last spring, and I first thought it was an update to ESP32-S3, but the new T-Dongle-S3 has quite more compact design and a smaller set of features that makes it suitable for data logging and displaying basic information over a wireless connection. T-Dongle ESP32-S2 development board specifications: Wireless SoC – Espressif Systems ESP32-S3 with Dual-core 32-bit Xtensa LX7 microcontroller up to 240MHz RISC-V ULP Co-processor 512KB SRAM 2.4GHz Wifi 4 (802.11b/g/n) Bluetooth 5.0 BLE + Mesh Storage 4 MB flash (or 16MB flash depending on where you look) MicroSD card socket cleverly “hidden” under the USB connector Display – Optional 0.96-inch 65K color IPS LCD (ST7735 SPI controller) with 160 x […]

LILYGO T-RGB round color touch display is powered by ESP32-S3R8 wireless microcontroller

LILYGO T-RGB is a wireless 2.1-inch round color touchscreen display based on ESP32-S3R8 dual-core microcontroller with WiFi 4 and Bluetooth 5.0 connectivity, 8MB PSRAM, and 16MB flash storage. The device also includes a microSD card socket for data storage and a Grove I2C connector for expansion and supports LiPo battery power. The company also says it can be charged through USB, so the board must include a battery charging circuit contrary to some other boards from LILYGO. LILYGO T-RGB specifications: SoC – Espressif ESP32-S3R8 dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration, 8MB PSRAM, WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage – 16MB SPI flash, MicroSD card socket Display – 2.1-inch round 18-bit RGB color IPS TFT display with 480×480 resolution (ST7701S SPI controller), touchscreen panel USB – USB Type-C port for power and programming Expansion – Grove I2C connector Misc […]

Unexpected Maker TinyS3, FeatherS3 and ProS3 boards feature ESP32-S3 dual-core wireless MCU

Seon Rozenblum, better known as Unexpected Maker, has launched upgrades to its ESP32-S2 boards such as the TinyS2 with ESP32-S3 variants, namely TinyS3, FeatherS3, and ProS3 boards. The new boards share the same form factors as the TinyS2, FeatherS2, and ProS2, but they get a more powerful dual-core microcontroller with AI instructions and 512kB SRAM. The microcontroller also adds Bluetooth 5.0 Low Energy (BLE) connectivity with Bluetooth Mesh support, instead of just WiFi 4 connectivity found in the earlier boards. TinyS3, FeatherS3, and ProS3 boards share the following features: SoC – Espressif Systems’ ESP32-S3 with Dual-core 32bit Xtensa LX7 microcontroller up to 240MHz RISC-V ULP Co-processor 512KB SRAM 2.4GHz Wifi 4 (802.11b/g/n) Bluetooth 5.0 BLE + Mesh Memory – 8MB QSPI PSRAM Flash – 8MB to 16MB depending on the model. USB – 1x USB Type-C connector with reverse back-feed protection for power and programming Antenna – 3D high gain […]

$5.5 Banana Pi BPI-PicoW-S3 ESP32-S3 board follows Raspberry Pi Pico W form factor

Banana Pi’s BPI-PicoW-S3 is a development board following the Raspberry Pi Pico W form factor, but based on Espressif System ESP32-S3 dual-core microcontroller offering both WiFi 4 and Bluetooth LE connectivity. The Raspberry Pi SBCs have inspired many designs, but the Raspberry Pi Pico MCU boards less so. So far, I had only seen the WeAct RP2040 board with the same layout except for a USB Type-C port and a 16MB flash. But the Banana Pi BPI-PicoW-S3 provides a direct alternative to the Raspberry Pi Pico W with a more powerful microcontroller, vector instructions for AI acceleration, BLE, and about the same price at $5.5 plus shipping. Let’s see how the BPI-PicoW-S3 specifications compare to the ones of the Raspberry Pi Pico W in the table below. While the power signal (5V, 3.3V, GND) and GPIO numbers are the same on both boards, there are a few variations here and […]
