AI Thinker Ai-WB2 modules feature BL602 RISC-V MCU with WiFi and BLE connectivity

AI Thinker has just introduced a new family of wireless IoT modules with the Ai-WB2 equipped with Bouffalo Lab BL602 RISC-V microcontroller offering both 2.4 GHz WiFi 4 and Bluetooth 5.0 LE connectivity. There are ten different modules to choose from, probably to keep mechanical and electrical compatibility with ESP8266 and ESP32 modules, and the company expects customers to integrate those into Internet of Things (IoT) products, mobile devices, wearables, Smart Home appliances, and more. Ai-WB2 modules share the following specifications: Wireless MCU – Bouffalo Lab BL602 32-bit RISC-V microcontroller @ up to 192 MHz with 276KB SRAM, 2.4 GHz WiFi 4 and Bluetooth 5.0 LE connectivity Storage – 2MB or 4MB SPI flash WiFi range – Up to about 500 meters (typical) I/Os – SDIO, SPI, UART, I2C, IR receiver, PWM, ADC, DAC, and GPIO (except Ai-WB2-01S with just UART/PWM/GPIO/ADC) Power Supply – 2.7V to 3.6V > 500mA Power […]

Linux 6.0 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.0 has just been released by Linus Torvalds: So, as is hopefully clear to everybody, the major version number change is more about me running out of fingers and toes than it is about any big fundamental changes. But of course there’s a lot of various changes in 6.0 – we’ve got over 15k non-merge commits in there in total, after all, and as such 6.0 is one of the bigger releases at least in numbers of commits in a while. The shortlog of changes below is only the last week since 6.0-rc7. A little bit of everything, although the diffstat is dominated by drm (mostly amd new chip support) and networking drivers. And this obviously means that tomorrow I’ll open the merge window for 6.1. Which – unlike 6.0 – has a number of fairly core new things lined up. But for now, please do give this most […]

ESP32 DevKitC V4 IoT development board ships with ESP32-WROOM-DA dual antenna module

The ESP32 DevKitC V4 is now selling with the ESP32-WROOM-DA module with two PCB antennas that was introduced last year in order to offer a longer WiFi range and better reliability. The development kit is exactly the same as the other ESP32 DevKitC V4 models, and the only difference is the dual antenna design. When running a recent version of the Arduino Core for the ESP32 (2.0.3 or greater), the ESP32 will automatically switch to the antenna with the strongest signal in order to deliver the best connectivity possible. ESP32 DevKitC V4 specifications: Wireless module – ESP32-WROOM-DA (PDF datasheet) with SoC – Espressif Systems ESP32-D0WD-V3 dual-core LX6 microprocessor with 520 KB SRAM, 2.4 GHz WiFi 4 and Bluetooth 4.1 connectivity Storage – 4MB SPI flash Two PCB antennas (ANT1 and ANT2) USB – 1x Micro USB port for power, programming, and debugging through USB-to-UART bridge up to 3 Mbps Expansion […]

Raspberry Pi RP2040 gets into BBC Micro:bit lookalike board

ELECFREAKS Pico:ed V2 is a Raspberry Pi RP2040 board heavily inspired by the BBC Micro:bit with an edge connector exposing rings suitable for crocodile clips, a 17×7 LED matrix display, and designed for the classroom. We’ve seen several BBC Micro:bit clones – or rather adaptations – over the years with boards such as the SiFive Learn Inventor, Elecrow Mbits, and HiHope “Big Brother” board. The Pico:ed V2 adds to the list, and the main differences are that it is based on the Raspberry Pi RP2040 microcontroller instead, and does not come with wireless connectivity relying on a USB interface only. ELECFREAKS Pico:ed V2 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB of SRAM Storage – 2MB QSPI flash Display – 17×7 dot-matrix display USB – 1x micro USB 1.1 port for power, data, and programming I/Os 25-pin notched “Wavy” connector with up to […]

LiLyGo T-SIMCAM ESP32-S3 camera development board supports optional 4G LTE connectivity

ESP32-S3 has been in the news recently and we just wrote about the Bee S3 and BPI-PicoW-S3 boards yesterday, but there’s more, and LilyGo T-SIMCAM ESP32-S3 is another interesting ESP32-S3 board with a 2MP camera as well as support for an optional 4G LTE module. The board can make use of the AI capabilities from the ESP32-S3 microcontroller through the built-in camera and microphone and offers two options for power with 5V through a USB Type-C port, as well as a 2-pin JST connector for connecting a battery. T-SIMCAM ESP32-S3 CAM board specifications: Wireless MCU – ESP32-S3R8 dual-core Xtensa LX7 microcontroller with WiFi 4 and Bluetooth 5.0 LE and Mesh connectivity with 8MB PSRAM Storage – 16MB QSPI flash, MicroSD card socket Camera – 2MP OV2640 camera with 1622×1200 resolution Audio – I2S digital microphone Connectivity – Optional NB-IoT, 2G GSM, or 3G/4G LTE module via mPCIe socket and SIM […]

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

Banana Pi BPI-PicoW-S3 Raspberry Pi Pico W alternative

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 […]

OpenHarmony development board borrows BBC Micro:bit edge connector

OpenHarmony development board BBC micro bit

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 […]
