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-WROOM-32 WiFi/Bluetooth module is in stock!

esp32-wroom32-1

ESP32-WROOM-32 modules are in stock now!

Again these are from the very first lot and with limited supply. To give chances to more developers to try them we will not allow more than 3 modules per order.

This module is good only if you develop your own board. For these who are not good with the soldering iron and SMD components soldering our advice is to wait for new supply of ESP32-CoreBoards or our own ESP32-EVB which will come with two Relays, Two buttons, SD-card connector, Ethernet 100Mbit and all signals on prototyping friendly 0.1″ step connectors.

Thanks for all who posted tips on our blog about ESP32-EVB feature wishlist!

EDIT: there was question on Twitter if these are original Espressif parts and why there is no FCC/CE markinig, my guess is that the certification is not complete, as it’s in the datasheet but not on module body. The modules come directly from Espressif, as you can see from reel label they are manufactured October 15th 2016 and one week later are in our stock for sale 🙂

ESP32-CoreBoard is sold out, ESP32-EVB design has started

esp8266-evb-bat-1

ESP32 is really hot, the first lot we got sold out for couple of days. If we didn’t put the restriction for one module per order it would be sold out in matter of hours, as people wanted to buy x5 and x10.

ESP32-WROOM-32 modules are shipped from Espressif and we wait them to arrive next week.

Meantime we started the design of our ESP32-EVB board.

What we think so far is to have these features:

  • power supply from 5V
  • LiPo charger and step up converter to allow un-interruptable power supply
  • Two relays 220VAC/15A
  • Two user buttons
  • UEXT connector to which you can connect many of our sensor UEXT boards, or to program the board with serial cable same way like ESP8266-EVB
  • status LEDs

With the two relays you will be able to switch on and off two different appliances.

With the sensors on UEXT you will be able to measure temperature, light, moisture etc. and log them.

The plan is to complete the design in October and start selling this board in November.

Our target is to release this EVB for EUR 15.00.

If you think we should add something else let us know.
