Sneak preview of new OSHW IoT board: ESP32-Gateway

ESP32-GATEWAY

ESP32-EVB really took us lot of time to complete mostly due to the not so complete documentation around Ethernet and our own silly errors. Also we wanted to add so many interfaces there to may people evaluate them all: Ethernet, CAN, Infrared, Relays LiPo UPS etc etc and the board become 75×75 mm. The price also went from EUR 22 to EUR 26.

In parallel we quietly were working on stripped version named ESP32-GATEWAY, as the name says we wanted just to keep here the connectivity: WiFi, BLE, Ethernet, USB for programming and micro SD card.

All available GPIOs are made on 0.1″ step strip at the bottom of the board, and two nice mount holes:

ESP32-GATEWAY-1

Today we assembled the first prototypes and we will test tomorrow. If everything is OK we will run production. We already have 100 blank PCBs ready as after so much time spent on ESP32-EVB we do not expect any troubles, but still wanted to reduce the risk to throw in the garbage bin more than 100 boards if we missed something.

So hold your breath if everything is OK we will have 100 boards for sale next week 🙂

The price of ESP32-Gateway will be EUR 22.

ESP32-WROVER-KIT is back in stock

esp32-wrover-kit

The popular ESP32-WROVER-KIT is back in stock!

 

EDIT: The new batch has ESP32-WROVER module on it:

ESP32-Wrover-2

Instead of CH340 USB to Serial now it have FT2232HL wich implements two Serial channels one for programming one for debugging.

Also as these were assembled end of May they contain WROVER modules with 4MB of RAM and ESP32 chip REV.1.

ESP32-EVB now get much better

ESP32-EVBESP32-EVB revision A was made quick and has too many errors 🙂 some were due to the non very clear documentation, like that we assumed that all ports could have internal pull-ups but  when we try to write the software we found that the GPIOs we used for the buttons has no such. Other were done by our engineer negligence.

We had small 100 pcs series from Revision A, but after all issues we encounter just decided to trash it and just move forward to revision B.

Now in Revision B all interfaces are tested and confirmed to work fine 🙂

What we keep:

  1. Two relays 250VAC/10A
  2. LiPo charger which allow ESP32 to work without external power supply
  3. Reset and User button
  4. micro SD card
  5. UEXT connector to add temperature, humidity, etc sensors
  6. GPIO with all signals available on 0.1″ proto friendly step connector

What we add:

  1. USB connector now is also used for automatic programming of ESP32 so no need for external serial cable, with DTR and RTS bootloader mode is entering automatically
  2. Ethernet now is correctly wired and works 🙂
  3. We were surprised to read ESP32 has CAN and we try and it works great, so in the new revision we add CAN driver
  4. We add Infrared transmitter and receiver, so now you can control all your home appliances with IR control like TVs, VCRs, Air conditioners, and everything else with IR control

What we removed:

  1. second button, with all above peripherals the ESP32-WROOM-32 module resources are gone, there is no single GPIO unused left

Revision B schematic can be reviewed here . The PCB is now routing.

Color TFT 2.8″ LCD 320×240 pixel display board with UEXT compatible to ESP32-EVB is also coming soon.

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

esp32-evbesp32-evb-2

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

Bitcoin price tracker with MOD-WIFI-ESP8266-DEV on Indiegogo

ticrthing

We got note that one of our boards MOD-WIFI-ESP8266-DEV is in the newly developed open source hardware product – Bitcoin price tracker

dwyasvjcn75xupzt2tvq

They are running now Indiegogo crowdfunding campain. We wish them success!

As being open source this product could be easily re-programmed to track price trends of other goods as well, like gold, silver, tin, why not DDR memory and Flash memory prices, and to give you alterts when the price go above or below given price point?

ESP32-CoreBoard V2 is in stock

esp32-coreboard

So anticipated ESP32-CoreBoard is now in stock!

We expect next week some quantity of just the modules ESP32-WROOM-32, they will be on web for sale for EUR 6.00/ea

OpenFest 2015 is 7 and 8th of November in Sofia

Screenshot from 2015-10-29 12-05-59

Next weekend in Sofia will be held the biggest event for Free/Open Source technologies in Bulgaria – OpenFest which is run every year since 2003.

Olimex is approved for talk and workshop yay!

The lecture is in Saturday at 17.00 o’clock and we will show what we have been working mainly this year:

“Physical computing and IoT with Open Source Software and Hardware”.

We will demonstrate how easy is to connect physical objects to Internet with our new ESP8266 boards, and our plug and play firmware which recognizes the UEXT modules connected to ESP8266 like: electricity metering, LED displays, Fingerprint sensors, door locks, relays, buttons. etc. We will shop how to display Twitter messages on LED matrix display, how to make door lock with fingerprint sensor, how to implement DO button for IFTTT directly with ESP8266 by secure connection with 2048bit encryption, and how to connect and switch loads and measure what energy they consume.

Specially for Open Fest we made our new WiFi enabled LED 8×8 badge. It contains ESP8266 and can be programmed to do lot of stuff, like to display all tweets with hashtag #openfest2015 or to display what are the lectures which run now and in which rooms by connecting to Open Fest program web page and extracting the necessary info.

WiFi-BADGE

Needless to say WiFi Badge is OSHW and all software project sources will be on GitHub (sorry still work on the software and can’t upload yet, we will do this early next week keeping the good developer’s traditions everything to be complete and debugged in the last minute 😉 ).

WiFi-BADGE-3

As you can see all ESP8266 GPIOs are exposed on this badge so it is good also for development board, power supply is done with single 1.5V AA battery only!

The workshop will be about SMD component soldering, we will bring some Binary Watch Kits with us and teach you how to solder your own Binary Watch. These who already have been at TuxCon do remember these watches:

Looking forward to see you there 🙂
