ART-Pi II development board features 600 MHz STM32H7R7 Cortex-M7 MCU with NeoChrom GPU

STM32H7R7 development board

The 600 MHz STM32H7R/S Cortex-M7 microcontroller family with an optional NeoChrom  2.5D GPU and up to 640 KB SRAM and 64 KB flash was introduced in 2024. However, apart from ST’s own development boards such as the NUCLEO-H7S3L8 and STM32H7S78-DK, we hadn’t seen any boards based on it. The ART-Pi II development board changes that. It’s a compact board powered by an STM32H7R7L8H microcontroller paired with 32 MB HyperRAM and 64 MB HyperFlash, and featuring a microSD card slot, an RGB LCD connector, WiFi 4 and Bluetooth 5.1 connectivity, two USB-C ports (OTG and Debug), a 40-pin Raspberry Pi-compatible GPIO header, a 28-pin GPIO header, two Qwiic connectors, and an on-board debugger. ART-Pi II board specifications: MCU – STMicro STM32H7R7L8H CPU core – Arm Cortex-M7 @ up to 600 MHz GPU – NeoChrom 2.5D GPU Memory – 64 KB flash Storage –  620 KB SRAM Package – TFBGA225 Memory – […]

WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)

WiQwiic-32 USB-C development board

Hack The Board’s WiQwiic-32 is a small USB-C IoT development board based on an ESP32-S3-WROOM-1 Wi-Fi and Bluetooth module, and equipped with a 1.14-inch LCD and eight Qwiic ports for easy prototyping with compatible modules. It also features a microphone and a buzzer for audio interaction, four buttons, two RGB LEDs, and a power LED.  There aren’t any through-holes for GPIO pins, so expansion is only possible through the Qwiic connectors, although you can always add a Qwiic to header converter module if you ever need breadboard-compatible GPIO headers. WiQwiic-32 specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM Storage – TBD Wireless – WiFi 4 and Bluetooth LE 5 Antenna – PCB antenna Display – 1.14-inch TFT display Audio On-board buzzer Built-in microphone for voice and sound detection USB […]

SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

SparkFun Thing Plus ESP32 C5

Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications. SparkFun Thing Plus – ESP32-C5 specifications: Wireless module –  ESP32-C5-WROOM-1 SoC – Espressif Systems ESP32-C5 CPU Single-core […]
