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 […]

Miniature Raspberry Pi CM4 carrier board only exposes USB-C port and 40-pin GPIO header

Mirek Folejewski’s (aka Mirko Electronics) PicoBerry is an open-source hardware, miniature Raspberry Pi CM4 carrier board with just a USB Type-C port for power, a 40-pin Raspberry Pi GPIO header, and barely anything else. At just 70x20mm, the 2-layer board only adds a few LEDs, namely the ACT/PWR LEDS and two user LEDs, and supports any Raspberry Pi CM4 module with eMMC flash, but not the Raspberry Pi CM4 Lite since the board does not include a microSD card slot. PicoBerry specifications: Supported system-on-modules – Raspberry Pi CM4 with eMMC flash, and possibly compatible SoMs such as Radxa CM5 or Pine64 SoQuartz64 USB – USB Type-C for power Expansion – 40-pin GPIO header with the same layout as on Raspberry Pi 4 or other Pi boards with a 40-pin header Misc – ACT/PWR LEDs, 2x user LEDs (green.red) Power Supply – 5V DC/3A via USB-C port, Dimensions – 70x20mm (2-layer […]
