SunFounder Zeus Car Kit review – A fun toy and Arduino learning tool

SunFounder Zeus Car Kit is an Arduino UNO and ESP32 Cam-based educational kit for children (and adults) that can be used to learn more about electronics, robotics, and programming. It’s a car comprised of four 6cm Mecanum wheels for omnidirectional motion and various sensors that can be controlled with an Android app enabling first-person view (FPV) thanks to the built-in camera. The company sent us a Zeus Car Kit for review and evaluation, and after assembly, we’ll use it in “Play Mode”, or in other words a toy that basically works out of the box, before checking out the “Programing Mode” and related Arduino tutorials to evaluate it’s educational potential. Zeus Car Kit Unboxing The kit comes in a nice retail package which highlights some of the capacities of the kit: FPV, Omnidrive, AI vision, compass, IR control, APP control, and RGB lights. The package itself contains four more boxes […]

eModGATE Moduino X0 – An ESP32-based industrial IoT controller with battery support

eModGate X0 ESP32 industrial IoT controller

TECHBASE eModGATE Moduino X0 is an industrial IoT control based on a choice of ESP32 modules from Espressif and Pycom, equipped with a battery slot for remote installations, and various interfaces to connect sensors or actuators via RS232, RS485, and/or digital I/Os. We first wrote about TECHBASE Moduino-X series ESP32 IoT endpoints almost six years ago with the X1 and X2 models, but since then the company has added more models such as the large X3 and X4 devices with more I/Os, and the new entry-level Moduino X0 that’s similar to the X1, but with battery support instead of a supercapacitor. eModGATE Moduino X0 specifications: ESP32 wireless module/board options ESP32-WROVER with ESP32 dual-core Tensilica LX6 processor @ 240 MHz, 8MB PSRAM, 4MB or 16MB SPI flash Pycom WiPy 3.0 with 4MB RAM, 8MB Flash Pycom SiPy with 512kB RAM, 4MB Flash, Sigfox Pycom LoPy with 4MB RAM, 8MB Flash, Wi-Fi/BT4.2, […]

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, […]

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

ESP SR ESP32 on device speech recognition AFE

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 […]
