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 […]

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 […]

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 […]

Pinecil V2 soldering iron gets BL706 Bluetooth LE RISC-V MCU, USB PD EPR support

PINE64 is about to launch the second generation Pinecil RISC-V soldering iron with the Pinecil V2 featuring a new Bouffalo Lab BL706 RISC-V microcontroller with Bluetooth LE connectivity, optimizations for higher power levels, as well as tentative support for the new USB PD EPR standard (Extended Power Range) working at up to 28V. I don’t solder every day, but when I do, I use my Pinecil soldering iron, as it’s heating super fast and does the job, and in my case, works quite better than the TS100 soldering iron. So it should come as no surprise that the Pincel is the most popular consumer hardware from the PINE64 community (after SOPine modules), and the new Pinecil V2 is a welcome upgrading building on the same design but with Bluetooth LE connectivity and a lower tip resistance. Pinecil V2 preliminary specifications: MCU – Bouffalo Lab BL706 32-bit RISC-V microcontroller @ 144 […]

CherryUSB – A lightweight USB device/host stack for embedded systems

CherryUSB USB stack for embedded systems

CherryUSB is a lightweight open-source USB device/host stack for embedded systems with one or more USB interfaces. The stack implements various class drivers such as CDC, HID, MSC, audio, video, and so on. It’s apparently part of Boufallo Lab SDK (e.g. for BL702 MCU), and has been ported and tested with WCH CH32V307 RISC-V MCU, STMicro STM32F4, and Nuvoton NUC442 Cortex-M4 microcontroller, as well as a two Arm Cortex-M3 microcontrollers I’ve never heard of: EastSoft ES32F3 and MindMotion MM32L3xx. CherryUSB device stack highlights: Support for USB2.0 full and high speed Endpoint irq callback USB classes support Composite Device Communication Device Class (CDC) Human Interface Device (HID) including “Custom HID” Mass Storage Class (MSC) USB VIDEO Class (UVC1.0,UVC1.5) USB AUDIO Class (UAC1.0, UAC2.0) Device Firmware Upgrade CLASS (DFU) MIDI CLASS (MIDI) Test and Measurement CLASS (TMC) Vendor class Remote NDIS (RNDIS) support Support WINUSB 1.0,WINUSB 2.0 with BOS (Binary Device Object […]

$1.8 XT-ZB1 Zigbee & BLE devkit features BL702 RISC-V module

Bouffalo Labs BL702 is a 32-bit RISC-V microcontroller with a 2.4 GHz radio for Zigbee 3.0 and Bluetooth 5.0 LE connectivity that we first found in the Sipeed RV-Debugger Plus UART & JTAG debug board that did not make use of the radio at all. But a BL702 development kit was brought to my attention, with the XT-ZB1 devkit equipped with a Zigbee & BLE module of the same name, and sold for just $1.80 per unit on Aliexpress. Shipping adds $4.63 where I live, but they also offer packs of 5 or 10 with the same shipping fee, meaning if you buy 10 the total cost should be around $22 including shipping, or around $2.2 per board. Alternatively, the module alone goes for $1. XT-ZB1 devkit specifications: XT-ZB1 wireless module with MCU – BL702C 32-bit RISC-V microcontroller @ 144 MHz with FPU, 132KB RAM, 192KB ROM, 1Kbit eFuse Storage […]
