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 […]

Femto is a tiny 12x12mm Raspberry Pi RP2040 module

Mirek Folejewski has designed the ridiculously tiny Femto module based on the Raspberry Pi RP2040 microcontroller with a size of just 12x12mm, and still including an SPI flash, a crystal, and a few passive components. We’ve previously covered some really tiny RP2040 boards with the Pimoroni Tiny 2040 and Adafruit QT Py RP2040 boards, as well as the RP2040 Stamp module, but the 12x12mm Femto module is about a quarter of the size of 25x25mm RP2040 Stamp. Femto specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB of SRAM Storage – 4 to 64Mbit QSPI flash I/O – 30 GPIO pins, Reset and BOOTSEL signals, etc… exposed through a frame (See below) Misc – Status LED, 12MHz crystal oscillator, decoupling capacitors Dimensions – 12 x 12mm The board is comprised of two parts: the module itself (aka mainboard) with the Raspberry Pi RP2040 microcontroller […]

52Pi CM4 Router Board also features HDMI, 40-pin Raspberry Pi HAT header, and OLED display

We’ve already seen compact Raspberry Pi CM4 based router boards with two Ethernet ports from DFRobots, Seeed Studio, and MCUZone. 52Pi CM4 Router Board expands on the same principle but also offers HDMI output, a 40-pin GPIO header for Raspberry Pi HAT expansion boards, and a small OLED information display. The board also includes two Gigabit Ethernet, plus the WiFi and Bluetooth connectivity from the Raspberry Pi CM4, and the extra features make the board larger (146x50mm) than competitors. But that makes the platform that much more flexibly, and can be used as a gateways for all sorts of projects thanks to the wide range of Raspberry Pi HAT available in the market. 52Pi CM4 Router Board (EP-0146) specifications: Compatible with Raspberry Pi Compute Module 4 series Storage – MicroSD card slot (only used with Raspberry Pi CM4 Lite) Video Output – HDMI 2.0 port up to 4Kp60 Display – […]

mini PCIe module features Rockchip RK1808K SoC with 3.0 TOPS NPU

Toybrick RK1808 mPCIe AI accelerator card

Rockchip RK1808 SoC with a built-in 3.0 TOPS AI accelerator has been around since 2019, and we’ve seen it in USB compute sticks, SBCs, and even in Pine64 SoEdge-RK1808 SO-DIMM module, but somehow never in the more widely used M.2 or mPCIe form factors. Toybrick TB-RK1808M0 changes that and offers Rockchip RK1808K SoC coupled with 1GB RAM and an 8GB eMMC flash in a mini PCIe module that exposes USB 3.0, USB 2.0, UART, and GPIO signals.
