ESP32-EVB our new board for IoT first prototypes are ready

ESP32-EVB is our new board with ESP32-WROOM32 module. It has:

• ESP32-WROOM32 module
• two relays 10A/250VAC
• Ethernet 100Mb interface
• LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery
• microSD card connector
• two user buttons
• UEXT connector to attach different sensors and modules
• 40 pin GPIO 0.1″ step connector with all resources of ESP32
• 5V power jack
• three mount holes

Now time to write some examples and if everything works to launch production.

The sale price will be EUR 22.00

Friday Free Board Quiz issue #25 is RPI-UEXT + MOD-IO2

RPI-UEXT allow Raspberry Pi to have access to different modules see original blog post we made about it: https://olimex.wordpress.com/2012/11/21/raspberry-pi-gpio-to-breadboard-and-uext-adapter/

MOD-IO2 allow RaspberryPi to control 2 relays and to read/write 7 additional GPIOs, including Analog inputs. On top of this MOD-IO2 is stackable and addressable so you can stack and connect to Raspberry Pi as many relays as you need for your project.

You have chance to win RPI-UEXT + CABLE26-pin + MOD-IO2 today if you answer correctly our quiz question!

Today at 17.00 o’clock our local Bulgarian time (GMT+2) we will post on Twitter our questions.

You have one hour to reply to our tweet with the correct answer.

At 18.00 o’clock we will count the correct answers and ask random.org to generate random number in range then announce the winner and ship the board by airmail in Monday.

Good Luck!

iMX233-OLinuXino-MAXI and lot of Relay IOs through MOD-IO

MOD-IO is UEXT module with 4 relays and 4 optoisolated inputs, the great thing is that many MOD-IO could stack together and this way you have access virtually to unlimited number of IOs.

This project on GitHub make iMX233-OLinuxino-MIAXI to talk and control MOD-IOs https://github.com/OLIMEX/OLINUXINO/tree/master/SOFTWARE/iMX233/MOD-IO
