Ambiq Apollo2 Blue Ultra Low Power MCU adds Bluetooth Connectivity

Ambiq Micro unveiled their ultra-low power Apollo MCU back in 2015 with claims of Cortex-M4 performance at Cortex-M0+ energy efficiency by leveraging SPOT (Subthreshold Power Optimized Technology) technology that allows operating the microcontroller at very low voltages (less than 0.5V). Since then the company introduced Apollo2 MCU with 10 μA/MHz power consumption, but still a generic purpose microcontroller. Earlier this year, the company unveiled a new version of Apollo2 microcontroller adding Bluetooth connectivity, and allowing Bluetooth applications that last years on a charge. Meet Apollo2 Blue. Apollo2 Blue key features and specifications: Arm Cortex-M4 Processor up to 48 MHz with FPU, MMU, wake-up interrupt controller with 32 interrupts Ultra-low power memory Up to 1 MB of flash memory for code/data Up to 256 KB of low leakage RAM for code/data 16kB 1 or 2-way Associative Cache Bluetooth 5 Low Energy RF sensitivity – -95 dBm TX: 5mA @0 dBm; RX: […]

VisionSOM-RT is an Industrial System-on-Module based on NXP i.MX RT Arm Cortex-M7 Processor

It’s hard to keep up with all the systems-on-module based on Arm Cortex-A “application class” processors, but so far I can’t remember seeing any Arm Cortex-M “microcontroller class” SoM. However, SoMLabs is currently working on VisionSOM-RT, a system-on-module based on NXP i.MX RT 1050 Arm Cortex-M7 processor clocked at 600 MHz. NXP i.MX RT series processors are actually promoted as a “crossover” processor delivering application processor performance with real-time capabilities right at the edge between the two classes of processors. VisionSOM-RT (SLS12Rx) module preliminary specifications: SoC- NXP i.MX RT Arm Cortex-M7 processor @ up to 600MHz with NXP PXP 2D graphics accelerator, and Graphics Engine PXP PiXel processing pipeline for imagine resize, rotation, overlay and color space conversion. Memory – 512kB on-chip RAM memory, up to 32MB SDRAM Storage – Up to 16MB QuadSPI flash, optional 4GB eMMC flash 200-pin SO-DIMM edge connector with Display Interface – 8/16/24-bit Parallel RGB […]

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 […]

ESP32-WROOM-32D / ESP32-WROOM-32U WiFi & Bluetooth Modules Deliver Better RF Performance

ESP-WROOM-32 is likely the most popular ESP32 WiFi + Bluetooth module on the market, but a few months ago, Espressif Systems unveiled two variants named ESP32-WROOM-32D / ESP32-WROOM-32U, which are based on ESP32-D0WD (5x5mm package) instead of ESP32-D0WDQ6 (6x6mm package), and are said to offer better RF performance ESP32-WROOM-32D is the most similar to ESP-WROOM-32 since it also comes with a PCB antenna, while ESP32-WROOM-32U is much smaller as it relies on an external WiFi/Bluetooth antenna via a u.FL connector. Both new modules are pin-to-pin compatible with ESP-WROOM-32 Key features: CPU – Espressif ESP32-D0WD dual core Tensilica processor Storage – 32Mbit SPI flash Crystal – 40 MHz Connectivity – Wi-Fi 802.11 b/g/n up to 150 Mbps, Bluetooth 4.2 LE I/Os – 38- catellagated pin with I/Os + GND plane Antenna ESP32-WROOM-32D – on-board antenna ESP32-WROOM-32U – u.FL connector for external IPEX antenna Dimensions ESP32-WROOM-32D – 18 x 25.5 x 3.1 […]
