Firefly RK3588 Android 12 SDK

Firefly ITX-3588J mini-ITX motherboard powered by Rockchip RK3588 processor was introduced at the beginning of the month, and now the company has started selling samples for the Core-3588J system-on-module and taken the opportunity to release the Rockchip RK3588 TRM (technical reference manual), and Android 12 firmware and SDK. Firefly Core-3588J module Before we check out the new documentation and Android software development kit, let’s have a quick look at Firefly Core-3588J module specifications: SoC – Rockchip RK3588 octa-core processor with  four Arm Cortex-A76 cores @ up to 2.4 GHz, four Arm Cortex-A55 cores, ArmMali-G610 MP4 quad-core GPU with support for OpenGL ES3.2, OpenCL 2.2, Vulkan1.1, 6 TOPS NPU, 48MP ISP, 8Kp60 video decoding, 8Kp30 video encoding System Memory – 4GB, 8GB, 16GB, or 32GB LPDDR4/LPDDR4x/LPDDR5 memory Storage – 16GB, 32GB, 64GB, or 128GB eMMC flash 314-pin MXM 3.0 edge connector for peripherals interfaces including HDMI 2.1 outputs, HDMI 2.0 input, […]

802.11ah WiFi HaLow development board launched for $99 (Crowdfunding)

802.11ah Halow development board

When 802.11.ah WiFi operating in the 900 MHz frequency range for low-power long-range communication was announced in 2014, then named WiFi HaLow in 2016, I naively assumed it would soon compete against other LPWAN standards like LoRaWAN or Sigfox. However, over the next few years, we did not see much interest in the wireless standard. But it may be picking up now, as Gateworks recently announced a Newracom NRC7292 based 802.11ah WiFi HaLow Mini PCIe module for their Arm Linux SBC’s, and a company called TELEDATICS has now introduced the Halo TD-XPAH 802.11ah Hallow development board featuring an AzureWave AW-HM482 module. Halo TD-XPAH board specifications: 802.11ah WiFi HaLow connectivity AzureWave AW-HM482 module based on Newracom NRC7292 Cortex-M3/M0 SoC with 752KB RAM, 2MB flash Compliant with IEEE 802.11ah WiFi HaLow operating in 902.0 ~ 928.0 MHz range Up to 15 Mbps data rate Up to at least 1km range, but can […]

SparkFun Raspberry Pi RP2040 & MicroMod boards take mikroBUS Click expansion boards

MicroMod & RP2040 MikroBus Click boards

We’ve previously written articles about boards featuring the mikroBUS interface supporting thousands of Click expansion boards from Mikroelectronika, and now the company has collaborated with Sparkfun who launched MicroMod and Raspberry Pi RP2040-based boards with a mikroBUS socket, plus Qwicc connectors. Raspberry Pi RP2040 is the well-known dual-core Arm Cortex-M0+ microcontroller found in Raspberry Pi Pico and a range of third-party boards, while Sparkfun MicroMod‘s are M.2 MCU modules with chips from Microchip, Nordic Semi, Ambiq, Espressif Systems, and NXP. Sparkfun RP2040 mikroBUS development board specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller up to 133 MHz with 264 KB SRAM Storage – 16MB QSPI flash, MicroSD card socket (on the bottom side) USB – USB Type-C port Expansion mikroBUS Socket 2x Qwiic connectors Thing Plus (or Feather) pin form factor with 18 GPIO pins including up to 4x 12-bit ADC, up to 8x 2-channel PWM, up to […]

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

XT-ZB1 Zigbee development board

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 […]

Imagination introduces Catapult RISC-V CPU cores

Catapult RISC-V CPU

As expected, Imagination Technologies is giving another try to the CPU IP market with the Catapult RISC-V CPU cores following their previous unsuccessful attempt with the MIPS architecture, notably the Aptiv family. Catapult RISC-V CPUs are/will be available in four distinct families for dynamic microcontrollers, real-time embedded CPUs, high-performance application CPUs, and functionally safe automotive CPUs. The new 32-/64-bit RISC-V cores will be scalable to up to eight asymmetric coherent cores-per cluster, offer a “plethora of customer configurable options”, and support optional custom accelerators. What you won’t see today are block diagrams and detailed technical information about the cores because apparently, all that information is confidential even though some Catapult RISC-V cores are already shipping “in high-performance Imagination automotive GPUs”. The only way to get more details today is to sign an NDA. Having said that we have some more information about the target markets and development tools.  Imagination Capapult […]

HLK-W801 board features Alibaba Xuantie XT804 based MCU with WiFi 4, Bluetooth LE 4.2

WinnerMicro W801 wireless MCU board

Earlier this month, we wrote about the 240 MHz WinnerMicro W806 Alibaba Xuantie XT804 C-Sky microcontroller with 1MB flash, 288KB SRAM found in the $2 HLK-W806 development board. But the company has a nearly identical WinnerMicro W801 microcontroller that bumps the internal flash to 2MB, and more importantly adds a 2.4 GHz radio with WiFi 4 and Bluetooth LE 4.2 connectivity, and HiLink also released the HLK-W801 board that’s nearly identical to HLK-W806, except for some extra LEDs, a USB-C port instead of a Micro USB port, and a longer form factor to make space for the PCB antenna. HLK-W801 board specifications: MCU – WinnerMicro W801 32-bit Alibaba XT804 microcontroller @ 240 MHz with 2MB Flash, 288KB RAM, FPU, DSP, crypto engine, 2.4 GHz radio Connectivity 802.11b/g/n WiFi 4 up to 150 Mbps supporting station, soft AP and station+soft AP modes, WPA2 security Bluetooth 4.2 Expansion – 2x 24-pin headers […]

Espressif introduces ESP32-S3-BOX AI development kit for online and offline voice applications

ESP32-S3-Box

Espressif Systems has very recently introduced the ESP32-S3-BOX AI voice devkit designed for the development of applications with offline and online voice assistants, and whose design I find similar to the M5Stack Core2 devkit, but the applications will be different. The ESP32-S3-BOX features the latest ESP32-S3 processor with WiFi and BLE connectivity, AI capabilities, as well as a 2.4-inch capacitive touchscreen display, a 2-mic microphone array, a speaker, and I/O connectors with everything housed in a plastic enclosure with a stand. ESP32-S3-BOX specifications: WiSoC – ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with Wi-Fi & Bluetooth 5, AI instructions, 512KB SRAM Memory and Storage – 8MB octal PSRAM and 16MB QSPI flash Display – 2.4-inch capacitive touchscreen display with 320×240 resolution Audio – Dual microphone, speaker USB – 1x USB Type-C port for power and debugging (JTAG/serial) Expansion – 2x Pmod-compatible headers for up to 16x GPIOs Misc Power […]

WinnerMicro W806 240 MHz MCU finds it way into a $2 development board

W806 MCU development board

I’ve just been notified about an inexpensive board (HLK-W806) based on WinnerMicro W806 32-bit XT804 (XuanTie E804) microcontroller clocked at up to 240 MHz and equipped with 1MB flash and 288KB RAM. XuanTie is the microcontroller family from Alibaba’s subsidiary T-Head Semiconductor, notably XuanTie RISC-V cores, but I’ve just learned not all XuanTie cores are based on the RISC-V architecture, and as we’ll see below, Xuantie E804 core appears to be based on the C-Sky architecture. It may still be interesting, as it’s in the STM32 board price range (pre-2020), but with a much higher frequency, so let’s have a look. HLK-W806 development board specifications: MCU – WinnerMicro W806 32-bit XT804 microcontroller @ 240 MHz with 1MB Flash, 288KB RAM, FPU, DSP, crtypto engine Expansion – 2x 24-pin headers with (based on MCU specs) 1x SDIO host with support for SDIO 2.0, SDHC, MMC 4.2 1x SDIO device up to […]
