Arduino Nano ESP32

ESP32-S3 based Arduino Nano ESP32 board supports Arduino and MicroPython programming

The Arduino Nano ESP32 is an ESP32-S3-based WiFi and Bluetooth microcontroller board designed for IoT applications for hobbyists and enterprise use cases. The new Nano board comes with 8 MB  PSRAM and 16 MB flash storage and can be programmed with either the Arduino or MicroPython languages. It’s not the first ESP32 board from Arduino, as the Nano RP2040 Connect pairs a Raspberry Pi RP2040 MCU with an ESP32 module from u-Blox and the just-released Arduino UNO R4 WiFi marries a Renesas RA4M1 Arm Cortex-M33 MCU with an ESP32-S3-MINI-1 module. But the Arduino Nano ESP32 is different since it’s the first ESP32 board from Arduino where the Espressif chip is the only microcontroller onboard and handles both wireless connectivity and GPIOs. Arduino Nano ESP32 specifications: Wireless module – u-Blox NORA-W106-10B with MCU –  ESP32-S3 dual-core Xtensa LX7 microcontroller @ up to 240 MHz with vector extensions, 512KB SRAM, 384KB ROM, […]

ESP SR ESP32 on device speech recognition AFE

Espressif ESP-SR enables on-device speech recognition framework on ESP32-S3 and ESP32 WiSoCs

Espressif ESP-SR is a speech recognition framework enabling on-device speech recognition on ESP32 and ESP32-S3 wireless microcontrollers with the latter being recommended due to its vector extension for AI acceleration and larger, high-speech octal SPI PSRAM. The ESP-SR framework was first released on December 17, 2021 with version 1.0, before the v1.20 update was introduced in March of this year, but I only found out about ESP-SR offline speech recognition solution through a tweet by John Lee showing an ESP-SR demo video by @ThatProject. Comrades of the world, liberate your hands from the chains of typing and touching germy switches! Embrace the revolutionary power of speech recognition with ESP32-S3 + ESP-SR. Let your words flow freely, for the proletariat shall not be silenced by keyboards or bourgeois input… pic.twitter.com/bm3udteB3o — John Lee (@EspressifSystem) July 15, 2023 I initially was confused since ESP32 boards have supported speech recognition for years using […]
