ESP32-EVB-EA Open Source Hardware IoT development board with ESP32-WROOM-32U and external antenna is in stock

ESP32-EVB-EA

Our popular ESP32-EVB now can be ordered with external antenna version: ESP32-EVB-EA.

What is next? Nice metal box, we already have first prototype:

It’s not painted and looks not so good but once we run production it will look as good as BOX-LIME-BLACK:

Box production is scheduled for end of September.

Powered by the Open Source Community ideas KiCAD is leading with new useful features which are missing even in the high end paid “professional” CAD products

KiCAD got a lot of attention from Open Source and Maker community after Eagle was bought by Autodesk and moved to paid subscription model. This definitely was the most silly idea for CAD tool monetarization as on practice make all projects designed with Eagle owned by Autodesk and they can cut you from using them at any point they decide.

We know that in Open Source community size is vital for the project development. KiCAD obviously gained lot of community for the last two years and this starts to pay off.

Two weeks ago one interesting project was released:

Interactive HTML BOM generation plugin for KiCad EDA

Very useful tool for people who build prototypes it shows interactively where every part from the BOM to be placed on the board.

We didn’t have time even to check it while new amazing project is released:

This tool create KiCAD components by extracting the component info from PDF datasheet. Just imagine how much time this will spare when create 300-400 pin BGA component.

With such rapid development KiCAD is becoming leader with unique features which are missing the other paid “professional” CAD EDA products.

This once again proves the advantages of community driven Open Source development – the products become just better as many people think and develop together.

Water Level Switch and submersible water pump for your aquarium or home flowers watering automation in stock!

SNS-WATER-LEVEL

SNS-WATER-LEVEL is floating magnet with reed contact sensor with travel length of 50 mm. It allow you to switch on off small pump which to keep the fluid level constant and to refill it.  You can directly connect to Arduino or ESP32 IoT boards GPIO.

IMM-WATER-PUMP

IMM-WATER-PUMP is silent submersible water pump which can help you to filter the aquarium water or to watering your flowers at home. It works with 3VDC and consume 0.12A.

 

ESP32-POE Open Source Hardware IoT development board with WiFi/BLE/100Mb Ethernet with 802.3 POE is in stock!

ESP32-POE-1

ESP32-POE board is now in stock. The prices start from EUR 14.36 for 50 pcs order.

This board offers Open Source Hardware / FOSS solution and building block for distributed sensor network with power over existing LAN infrastructure.

Possible use cases are Home automation, Industrial machine logging, remote environmental monitoring, access control, remote displays etc.

The board contains ESP32-WROOM-32 module with WiFi/BLE and Ethernet connectivity , RESET and USER buttons, micro SD card, LiPo battery charger and LiPo connector which allow board to work even with power supply drops.

The UEXT connector on the board can be used to connect many different sensors like:

Si3402-B chipset takes care for the power over ethernet, it’s IEEE 802.3 compliant, including pre-standard (legacy).

Important notice, to keep board compact and as it’s main purpose is to connect to cloud different remote sensors there is no galvanic isolation between board and the power delivered by the LAN switch or router.

ESP32-POE has internal programming interface and you can program it with Espressif SDK or Arduino via USB cable. As the board is not galvanic isolated from the Ethernet power supply, before you connect the USB cable to your computer you should remove the Ethernet cable or you should use USB-ISO between your computer the ESP32-POE!

 

Nice tutorial for writing and debugging plain C on ARM Cortex-M3 STM32F103

OLIMEX-STM32-H103

Jacob Mossberg wrote nice tutorial how to program in C ARM Cortex-M3 with GCC and how to debug it with GDB and OpenOCD.

We like very much the hardware he is using 🙂 STM32-H103 and ARM-USB-OCD-H.

 

Our Summer Vacation is approaching!
