M5Stamp C3 RISC-V board supports WiFI 4, Bluetooth 5.0 Long Range and 2 Mbps bitrate

M5Stamp C3

It was only last month that M5Stack launched the M5Stamp Pico module based on an ESP32-PICO-D4 SiP and heat-resistant plastic shell, but M5Stamp C3 board is already out with most of the same specifications and features but an ESP32-C3 RISC-V SoC replaces the ESP32 dual-core Xtensa processor. M5Stamp C3 offers WiFi 4 and Bluetooth 5.0 with high bitrate and long-range connectivity and comes with the same heat-resistant plastic shell, but the company also highlights the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption as a more secure way to address Bluetooth security concerns. M5Stamp C3 specifications: WiSoC – ESP32-C3FH4 32-bit single-core RISC-V processor @ up to 160 MHz, with 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB embedded flash, WiFI and Bluetooth Connectivity 2.4 GHz WiFi 4, 20 MHz and 40 MHz bandwidth, IEEE 802.11 b/g/n protocol, up to 150 Mbps Bluetooth 5, Bluetooth mesh, with supports for 125 Kbps, […]

HarmonyOS development board shows up for $11

HarmonyOS development board

Last year, we noted the Hisilicon Hi3861 based HiSpark WiFi IoT development board with supports LiteOS and HarmonyOS that was available in China for just under $10, or as part of a devkit with baseboard and modules for around $60. Although not very practical, buying from Taobao was possible, but there’s now what appears to be a new revision of the Hi3861V100 based HarmonyOS development board in a wider form factor on Banggood for $10.99. Hi3861 development board specifications: MCU – Hisilicon Hi3861V100 32-bit RISC-V microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory, and WiFI 4 connectivity; QFN-32 5x5mm package WiFi 802.11b/g/n standard up to 72.2 Mbps @ HT20 2.4 GHz frequency band (ch1-ch14).

Blues Wireless Swan board adds castellated holes to Adafruit Feather form factor

Adafruit Feather Castellated holes

We’ve often written about Adafruit Feather-compatible boards in the past, but Blues Wireless Swan board is a little different, as the STM32L4-based board comes with castellated holes instead of just through holes which allows the board to expose up to 55 GPIOs, or 36 more pins than a traditional feather-compatible board. The company also introduced the “Feather Starter Kit for Swan” that enables the board to work with the company’s Notecard LTE Cat-M/NB-IoT M.2 modem that ships with 10-year (up to 500MB) of IoT connectivity, as well as GPS/GNSS connectivity. The Swan board Swan specifications: MCU – STMicro STM32L4R5 Arm Cortex-M4 microcontroller clocked at 120Mhz with 2MB of flash and 640KB of RAM USB – 1x Micro USB port for power and programming Castellated holes giving access to 55 GPIO including: 8x analog input 16x digital 4x I2C, 3x SPI 1x USB OTG full speed 1x 14-channel DMA 12-bit ADC, […]

PICMG IoT.1 firmware specification targets IoT sensors and effecters

PICMG IoT.1 firmware specifcation

The PICMG consortium is better known for COM Express and COM HPC standards for x86 industrial computers-on-module, but last year they started catering to the IIoT sector with the introduction of the microSAM System-on-Module (micro Sensor Adapter Modules) standard for microcontrollers and IIoT sensors. The consortium has now ratified the IoT.1 firmware specification defining a communication standard between sensors/effecters and local IoT controllers such as microSAM specified by PICMGs IoT.0 specification. The PICMG IoT.1 standard, developed in collaboration with the Distributed Management Task Force (DMTF), defines a vendor-agnostic firmware interface and low-level data model that builds upon the Platform Level Data Model (PLDM) low-level messaging system, and adds features specific to industrial automation and control use cases. If like me, you’ve never heard about PLDM, PICMG explains: The PLDM is a low-level messaging system that supports topologies, eventing and discovery and runs over a variety of system level buses such […]

WattUp 1W active energy harvesting developer kit enables at-a-distance wireless charging

WattUp 1W Active Energy Harvesting Transmitter

Two years ago, we noted Energous’ WattUp hearables developer kit that would charge earbuds with the company’s WattUp near-field wireless charging technology. The company has now introduced the WattUP 1W active energy harvesting developer kit capable of charging multiple IoT devices with at-a-distance wireless charging. The kit is said to be “active” because there’s a 6-inch transmitter, let’s call it a power gateway, and several IoT devices that harvest energy from it. Traditional passive solutions will harvest ambient energy from the surrounding environment, and may not deliver enough power, and do so unpredictably. The developer kit comes with the transmitter, plus one or more receiver units, and relies on the following main chips: Transmitter Dialog Semiconductor DA14682 SmartBond Bluetooth 5.0 Cortex-M0 SoC Dialog Semiconductor DA4100 Wireless Power Transmitter SoC Dialog Semiconductor DA3210 1W Power Amplifier A discrete rectifier and a DA2210 WPT rectifier Receiver(s) Dialog Semiconductor DA14531 Cortex-M0+ BLE 5.1 […]
