Amazon Alexa approves Espressif’s ESP AFE for ESP32-S3 AI & DSP

Amazon‘s website has introduced a Software Audio Front End (AFE) Development Kit section that lists software algorithms that optimize sound detection in noisy environments. The latest addition is the Amazon Alexa recently certified Espressif audio front end or ESP AFE algorithm for shorts.

Low resource consumption

Espressif’s AFE algorithms are optimized, as they take advantage of Espressif’s AI accelerator that is available in the ESP32-S3 SoC. Espressif’s AFE algorithms consume just 12-20% of CPU and around 460 KB of memory, including 220 KB of internal memory and 240 KB of external memory. This provides sufficient headroom for customer applications on the ESP32-S3 SoC.

Espressif’s AFE algorithms offer an easy and intuitive API for customer applications, so that their performance can change as dynamically as it is required. The distance between the two microphones can be between 20-80 mm, which allows considerable flexibility for the hardware design of developers’ end-products.

The Espressif AFE algorithm was certified by Amazon after achieving excellent performance in long-range Alexa testing. In most cases, in low signal-to-noise scenarios, the wakeup rate reaches 100% and the speech recognition rate exceeds 90%.

ModBerry M500 upgrades to Raspberry Pi 3 B+

The latest version of Raspberry Pi development board, Raspberry Pi Model 3 B+, is now available as a platform for ModBerry M500 industrial computer series. Raspberry Pi 3 Model B+ (Plus) offers has more computing power and much greater possibilities in the field of wired and wireless communication.

The biggest new feature introduced in 2016 is the Raspberry Pi 3 wireless support. Now the creators took a step forward and refined the solution. The new Raspberry Pi 3 Model B+ – supports two-band Wi-Fi (2.4 GHz and new 5 GHz), Bluetooth version 4.2  and Ethernet over USB 2.0 (up to 300 Mb / s). Upgraded ModBerry M500 series is powered by s more powerful heart, in the form of a Broadcom BCM2837B0 quad-core processor clocked at 1.4 GHz. Power-over-Ethernet support has also appeared, and heat dissipation has been improved.

ModBerry M500 vs ModBerry 500(CM3)

Standard ModBerry 500 series is based on Raspberry Pi Compute Module 3, an industrial version of commercial Raspberry Pi branch, with flagship Raspberry Pi 3 Model B+. Used Compute Module is more suitable for custom products, such as our ModBerry 500 industrial computer, which can be adapted to customer’s need with wide range of extension modules from TECHBASE. ModBerry equipped with CM3 can be configured to support chosen number of RS-232/485 serial ports, Digital and Analog I/Os, various setup of Ethernet/USB ports, CAN interface, 1-Wire and wireless modems: 3G/LTE, GPRS/EDGE, GPS, LoRa, ZigBee, Wireless M-Bus, NarrowBand-IoT and many more.

The updated M500 availability

Currently the updated M500 samples, are available on demand. Please contact TECHBASE’s sales department via http://modberry.techbase.eu/ contact form with specific requirements to receive an offer that will suit the project’s needs. Since the M300 update is still under the development, the pricing of each unit may vary on the basis of configuration and order quota

ModBerry expands to the latest NanoPi & OrangePi platforms

NanoPi recent additions to ModBerry series

Introduced in November 2017, the ModBerry M300 series, based on NanoPi NEO revolutionised the economic segment of Industrial IoT devices and proved, that automation and monitoring can be done effectively with low expenditure on industrial installations.

To ensure constant development of TECHBASE’s solutions and cutting-edge technology, the NanoPi platform part of ModBerry series is expanded by updated ModBerry M300 N2 product, based on NanoPi NEO2. The new addition features Quad-core Cortex-A53, twice more RAM than previous version of NanoPi NEO and Gigabit Ethernet for fast communication.

For even wider range of communication interfaces and application possibilities, TECHBASE offers now ModBerry M300 N2+ based on the NanoPi NEO Plus2. M300 N2+ is equipped with 8GB eMMC, features more USB ports, Gigabit Ethernet port like M300 N2 and is supported with onboard Wi-Fi/Blutetooth 4.0 to ensure many channels of data management.

ModBerry M300 series can optionally support an external 2.5″ SATA hard disk and 2242 SSD storage units with M.2 interface thanks to onboard JMS567 USB to SATA controller. With extra storage space, data management of specific installations would be more convenient than sending all unprocessed data into cloud or directly to user.

OrangePi capabilities

To meet the Industrial IoT market demands the ModBerry family joined new embedded computer platform, offering adjustable solutions for every industrial installation. ModBerry M300 O1/O2 series is formed by two OrangePi module boards offering different approach to IoT than NanoPi solutions.

ModBerry M300 O1 based on OrangePi Zero Plus features Allwinner H5 (Quad-core Cortex-A53) SoC, moderate 512MB RAM, storage memory option with microSD slot, USB and Gigabit Ethernet port. The wireless communication is supported with onboard Wi-Fi module.

Offering much higher performance and wider feature range, the ModBerry M300 O2 features same SoC as M300 series, but thanks to OrangePi Zero Plus2 means, the device is equipped with onboard 8GB eMMC, extra microSD expansion slot as alternative and wired/wireless interfaces, e.g. HDMI, Wi-Fi, Bluetooth 4.0.

ExCard modules to peak the performance

Every TECHBASE’s industrial computer is supported by ExCard add-on modules for extra RS-232/485 serial ports, Ethernet ports, PCIe slots, analog input and output, digital I/Os, relays, M-Bus interface, opto-isolation, accelerometer, etc. To provide specific communication paths, ModBerry can be rigged with additional Wi-Fi/Bluetooth module, 3G/LTE, NarrowBand-IoT, LoRa, ZigBee, GPS and Wireless M-Bus.

The latest options for ModBerry series are:

  • SuperCap expansion, to provide constant power supply as a UPS option
  • OLED 0.96” & new OLED 1,3″ screen, allowing the control without the need of connecting into the device
  • ESP32 module as a security chip, to add a firewall into control installation and ensure constant operation of the device, even with power drops and random events
  • Aluminum case, to grant much higher durability for extra harsh industrial conditions
  • Mentioned earlier SATA/M.2 SSD controller for extra data storage

LORA MQTT: Perfect Couple – in RaspberryPi & ESP32 Ecosystem

TECHBASE Industrial Computers are designed for easy integration of LoRa / MQTT networks. ModBerry devices base on Raspberry Pi / NanoPi / Intel UpBoard platform communicate with both Cloud and Sensor layer (backed with ESP32 Moduino devices) of your installation via MQTT protocol. Gateway utilizes the features of many protocol libraries, such as original TECHBASE’s iMod protocol controller – installable both on the Gateway device itself or externally with wide range of possibilities (industrial computer, hosted server, etc.). Our devices fully support Node-RED, CODESYS, OpenHAB and many more open protocol libraries.

Wide range of protocol support

All TECHBASE’s solution can be empowered with iMod software incl. protocol support for industrial interfaces, e.g. M-Bus, Modbus, SNMP, MQTT. iMod software works seamlessly with Node-RED using MQTT protocol, allowing use of bacnet and direct control over devices I/Os with Google’s platform-neutral protobuf – extensible mechanism for serializing structured data and zeroMQ controls to connect the code in any modern language, on any platform. The protocol drivers library can be expanded with CODESYS development system to support PROFIBUS, CANopen, EtherCAT, PROFINET and EtherNet/IP.
