Eduponics Mini is an ESP32-powered Smart Agriculture kit (crowdfunding)

Eduponics Mini ESP32 Smart Agriculture Board

One sector of the economy that should benefit the most from the Internet of Things is the agricultural sector, as environmental sensors are needed to optimize yields and also decrease costs with lower electricity and water usage. STEMinds Eduponics Mini Smart Agriculture kit is designed for this purpose. At the heart of the kit is an ESP32 board equipped with light, temperature, humidity, and barometric sensors, as well as interfaces to connect an external pump, a soil moisture sensor, a water quality sensor, and more environmental sensors. Eduponics Mini board specifications: Wireless module – ESP32-WROVER-B module with ESP32 Wi-Fi and Bluetooth SoC, 4MB QSPI flash, 8MB SPRAM, PCB antenna Built-in sensors BH1750 I2C light sensor BME280 I2C temperature, humidity, and barometric sensor Expansion 2-pin connector for 12V pump with built-in relay module 3-pin connector for soil moisture sensor or any other analog or digital device 4-pin connector for water quantity […]

Crowbits Master Kit Review – Part 1: A first look at the ESP32 based education kit

Crowbits STEM education kits comprised of magnetic modules launched on Kickstarter a couple of weeks ago. There are five kits increasing in difficulty with the Hello Kit just requiring the student to connect modules to get started, i.e. no programming required, to the Crowbits Master Kit based on a battery-powered ESP32 module suitable to create your own phone, portable game console, radar tower, etc… Elecrow sent me the latter for evaluation, and in the first part of the review, I’ll unbox the kit, see how modules mechanically fit together, and have a quick look at the user manual, before trying one or two projects from the manual in the second part. This is the second STEAM product from Elecrow that I review, as I reviewed CrowPi2 Raspberry Pi 4 laptop last year. Let’s open the package. We have a total of six modules with two joysticks, an ESP32 module with […]

QuickLogic’s Hearable Reference Design enables Alexa Voice-Initiated Devices

Working with QuickLogic's Smart Hearable Reference Design

Last year we saw QuickFeather board featuring EOS S3 Cortex-M4F MCU with embedded FPGA, which was a crowdfunding project. This year the company has launched its smart hearable reference design based on a similar processor by QuickLogic. The device is dedicated to “Voice-Initiated, Hands-Free, Alexa Built-In Devices with Close-Talk Support.” QuickLogic’s smart hearable reference design is based on the company’s Open Reconfigurable Computing (QORC) which supports a complete open-source set of development options for the MCU and FPGA devices. It is also built on the EOS S3 Voice Processor and the QuickFeather open source development kit. This can enhance the user experience with a longer battery life of the device. The EOS S3 Arm Cortex- M4 processor features Low Power Sound Detection (LPSD) technology along with DSP Concepts’ TalkTo noise suppression and beamforming technology for the directional transmission of signals. It also comes with Alexa Wake Word engine technology, an […]

tCam-Mini IR thermal camera board ships with ESP32 module

While there are plenty of ESP32 camera boards, it’s much harder to find off-the-shelf solutions with ESP32 wireless SoC and an IR thermal camera. That’s likely why Dan Julio decided to design tCam-Mini board combining an ESP32 module with a Flir Lepton 3.5 sensor with 160×120 resolution to capture radiometric data for thermographic analysis. tCam-Mini board hardware specifications: Wireless module – Espressif ESP32-WROVER-E module with dual-core ESP32-D0WD0V3 WiSoC, 8 MB PSRAM, 8 MB Flash, and PCB antenna; Camera – Flir Lepton 3.5: 160×120 pixel radiometric LWIR camera with shutter operating in either Radiometric/TLinear (each pixel contains temperature data) or AGC modes (no temperature data in each pixel but better images). Expansion – 4-pin I2C header Debugging – Micro USB port with CP2102N-A02 USB to UART bridge for ESP32 boot loader control Misc – Dual color (Red/Green) status LED, Factory/Wifi Reset button Power supply – 5V input via micro USB port […]
