OpenHarmony development board borrows BBC Micro:bit edge connector

HopeRun’s HiHope development board features a HiSilicon Hi3861V100 32-bit RISC-V microcontroller compatible with OpenHarmony OS and looks very much like the BBC Micro:bit educational board notably with its edge connector. The board is also designed for youth education (in China) and comes with similar sensors, but there are some differences such as a 0.96-inch OLED instead of an LED matrix and support for offline voice recognition. There’s no wireless connectivity apart from NFC support. HiHope board specifications: MCU – HiSilicon Hi3861 32-bit microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory Display – 0.96-inch OLED display with 128×64 resolution (SSD1306) Connectivity – NFC with R/W mode, card emulation,  and bidirectional mode USB – 1x USB Type-C port for power and programming Sensors – Temperature & humidity sensor, light sensor, microphone, 6-axis motion sensor Expansion – Edge connector with 5x rings (3x […]

ESP-Hosted simplifies adding WiFi connectivity to legacy Linux or MCU-based products

Most of the ESP8266 and ESP32 projects and products we cover here use the Espressif microcontroller as the main chip, but ESP8266 started as a WiFi module meant to be controlled with AT commands from a host device. But there are still “legacy” products that may benefit from connecting to the cloud, and Espressif introduced the ESP-Hosted for that purpose in 2020, and recently released a next-generation ESP-Hosted solution (ESP-Hosted-NG) specifically for Linux hosts. The solution is available in two variants: ESP-Hosted-FG (First generation) exposing an Ethernet interface to the host and suitable for microcontrollers and Linux hosts, and the ESP-Hosted-NG presenting an 802.11 network interface and designed for Linux hosts only. Both solutions include ESP32 firmware and a host driver running on the legacy system. Espressif Systems recommends using ESP-Hosted-FG on an MCU host, and ESP-Hosted-NG on a Linux host in order to benefit from Linux user space applications/services […]

Sipeed MetaSense RGB ToF 3D depth cameras are made for MCUs & ROS Robots (Crowfunding)

We’ve just written about the Arducam ToF camera to add depth sensing to Raspberry Pi, but there are now more choices, as Sipeed has just introduced its MetaSense ToF (Time-of-Flight) camera family for microcontrollers and robots running ROS with two models offering different sets of features and capabilities. The MetaSense A075V USB camera offers 320×240 depth resolution plus an extra RGB sensor, an IMU unit, and a CPU with built-in NPU that makes it ideal for ROS 1/2 robots, while the lower-end MetaSense A010 ToF camera offers up to 100×100 resolution, integrates a 1.14-inch LCD display to visualize depth data in real-time and can be connected to a microcontroller host, or even a Raspberry Pi, through UART or USB. MetaSense A075V specifications: SoC – Unnamed quad-core Arm Cortex-A7 processor @ 1.5 GHz with 0.4 TOPS NPU System Memory – 128 MB RAM Storage – 128MB flash Cameras 800×600 @ 30 […]
