Hexabitz Modular Prototyping Platform Enables Wire-Free 3D Electronics Designs (Crowdfunding)

A few years ago, I made a Raspberry Pi case made of perfboard and created some sort of DIY modular 3D electronics design by using the top and sides of the case to also hold electronics components and associated circuitry like a relay, and LEDs. The just launched Hexabitz hexagonal / pentagonal modules are designed to make prototyping easier, and also provide flexibility to create all sort of wire-free (3D) electronics designs with minimal soldering. A little over a dozen of modules are currently on offer, most with an STM32F0 Arm Cortex M0 micro-controller: Modules with built-in MCU 01R00, P01R00 – RGB LED (hexagon / pentagon) with Cree Tri-color (RGB) SMD LED, 4-Pin PLCC H02R10 – Bluetooth/BLE V4 based on Laird BT900-SA + chip antenna, +8 dBm max H04R00 – Audio amplifier, speaker, and headphone jack based on ST TS4990IST 1.2W audio power amplifier, 0.7W, 8 Ohm speaker H05R00 – SPI […]

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) […]

Think Silicon Ultra Low Power NEMA GPUs are Designed for Wearables and IoT Applications

When you have to purchase a wearable device, let’s say a smartwatch or fitness tracker, you have to make trade offs between user interface and battery life. For example, a fitness tracker such as Xiaomi Mi Band 2 will last about 2 weeks per charge with a limited display, while Android smartwatches with a much better interface need to be recharged every 1 or 2 days. Think Silicon aims to improve battery life of the devices with nicer user interfaces thanks to their ultra-low power NEMA 2D, 3D, and GP GPU that can be integrated into SoCs with ARM Cortex-M and Cortex-A cores. The company has three family of GPUs: NEMA|p pico 2D GPU with one core 4bpp framebuffer, 6bpp texture with/out alpha Fill Rate – 1pixel/cycle Silicon Area – 0.07 mm2 with 28nm process Power Consumption – leakage power GPU consumption of 0.06mW; with compression (TSFSc): 0.03 mW NEMA|t […]

Mediatek MT2533D is a Bluetooth 4.2 SiP for Smart Headphones & Hands-Free Systems

There used to be a time when most products were based on a general purpose MCU or processor that you would interface to over chips like audio codecs, memory chips, flash storage, etc…, but in order to cut costs, application specific SoCs have become quite common over the year, so we’ve had mobile application processors for several years already, but more recently we got “wearables” SoCs and “Smart Home” SoCs, and Mediatek has launched MT2533D “headphone” SiP (System-in-Package) combining a Cortex-M4 MCU, 4MB PSRAM, an audio codec, and a dual mode Bluetooth subsystem. Mediatek MT2533D specifications: MCU – ARM Cortex-M4 @ up to 208MHz with 32KB L1 cache, FPU, MPU, AES 128/192/256 crypto engine and TRNG Memory – 160kB SRAMs, 4MB pseudo SRAM Storage – 4MB flash Wireless Connectivity – Bluetooth 4.2 dual mode (classic and low energy) Audio AAC/SBC for Bluetooth audio CVSD/mSBC for Bluetooth speech PCM playback: 8-48kHz […]
