Bouffalo Lab BL616/BL618 RISC-V MCU supports WiFi 6, Bluetooth 5.2, and Zigbee

Bouffalo Lab BL616/BL618 is a 32-bit RISC-V wireless microcontroller with support for 2.4 GHz WiFi 6, Bluetooth 5.2 dual-mode, and an 802.15.4 radio for Zigbee, Thread, and Matter designed for IoT applications. We first spotted the BL616 RISC-V IoT MCU during the BL602/BL606 announcement in November 2020, but we had virtually no additional information about it so far. It appears both BL616 and BL618 will be launched next month with the main difference between the two being that BL616 has 19 GPIOs and BL618 comes with 35 GPIOs. Bouffalo Lab BL616 and BL618 specifications: MCU core – 32-bit RISC-V CPU (RV32IMAFCP) @ up to 320 MHz with FPU and DSP, 32KB instruction cache & 16KB data cache VPU – MJPEG video encoder Memory – 480KB SRAM, 4KB HBN RAM, embedded 4 or 8MB pSRAM (optional) Storage – 128KB ROM, 4Kb eFuse, embedded 2, 4, or 8MB flash (optional), XIP QSPI […]

Meadow F7v2 Feather STM32F7 MCU board supports .NET, C# programing

Wilderness Labs Meadow F7v2 Feather is an STM32F7 Arm Cortex-M7 development board following the Adafruit Feather form factor and programmable with C# through a lightweight implementation of the .NET framework. We had previously seen the .NET Framework running on Android and Linux thanks to Xamarin’s Mono, but I don’t think I had ever a microcontroller-class board supporting the .NET framework and C# programming. But that’s exactly what the Meadow F7v2 Feather does. Meadow F7v2 Feather specifications: MCU – STMicro STM32F7 Arm Cortex-M7 microcontroller @ 216 MHz with 2D graphics and JPEG accelerators Memory – 32MB RAM Storage – 64MB flash Connectivity – 2.4 GHz WiFi and BLE (ESP32) with onboard and external u.FL antennas USB – 1x Micro USB port for power and programming Expansion with through and castellated holes with up to 25x GPIO, 12x PWM, 6x analog inputs, 2x DAC, I2C, I2S input/output, SPI, UART, CAN Bus Misc […]

DROPLET irrigation system works with ESPhome and Home assistant

When PricelessToolkit failed to find an affordable (indoor) irrigation system that works with Home Assistant and ESPHome, he built the DROPLET board based on ESP32 wireless SoC and supporting up to five micro-pumps and soil moisture sensors. The board also comes with switches to manually control the pump, a built-in DS18B20 temperature sensor, a buzzer, and a I/O header to connect an expansion header for relay control, I2C, GPIOs, and an external DS18B20 temperature sensor. DROPLET specifications: Wireless module – ESP32-S with ESP32 dual-core 32-bit microcontroller @ 240 MHz with 2.4 GHz WiFi and Bluetooth connectivity, 4MB SPI flash Display – I2C header for 5V/3.3V OLED display Pump interfaces – 5x 2-pin connectors for micropumps Sensors and sensor interfaces DS18B20 temperature sensor 5x 3-pin connectors for soil moisture sensors; pulled low with a 1 MΩ resistor. Expansion – 2x 16-pin right-angle female header with GPIOs, UART, 5V, and GND Debugging […]

EdgeBox-ESP-100 – An ESP32-S3 industrial controller with RS485, CAN Bus, DIO, 4G LTE, and more

We’ve previously covered the EdgeBox-RPi4 industrial controller powered by a Raspberry Pi Compute Module 4 and plenty of I/Os such as RS485, RS232, digital inputs and outputs, and connectivity options such as Gigabit Ethernet, WiFi 5, Bluetooth 5, and 4G LTE. But if you don’t quite need the power of a Linux controller, the EdgeBox-ESP-100 industrial edge controller based on an ESP32-S3 dual-core WiFi and Bluetooth microcontroller and offering a similar set of features, albeit with twists, may be an interesting option. EdgeBox-ESP-100 specifications: Microcontroller – Espressif Systems ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240 MHz with AI vector instructions, 512KB RAM Memory – 8MB PSRAM Storage – 16MB Flash Network connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth 5.0 LE via ESP32-S3 4G LTE cellular via SIMCom A7670G LTE Cat 1 module Optional support for LoRa (replaces the A7670G module) Serial & I/Os via terminal blocks […]

Pinecil V2 Bluetooth LE soldering iron gets a web interface

It’s now possible to make use of the Pinecil V2 soldering iron‘s Bluetooth LE connectivity through a web-based interface used to monitor and/or set the temperature and power of the RISC-V soldering iron. When the Pinecil V2 soldering iron was launched with a Bouffalo Lab BL706 RISC-V Bluetooth microcontroller last summer, we were told there were main potential cases to make use of the Bluetooth LE features: OTA firmware upgrade and remote telemetry and control. The latter is now being taken care of by Joric who has written a web application to visualize telemetry data and even control the temperature of the soldering iron. To be able to use the Bluetooth features, you’ll first need to install the latest Pinecil V2 firmware with blisp flashing utility before going to https://joric.github.io/pinecil to pair your soldering iron as explained in the wiki. Note the implementation relies on the Web Bluetooth API which […]
