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!

 

Espressif got new competitor RDA5981 dedicated for IoT and audio apps

0

Few years ago Espressif released their first low cost WiFi chip ESP8266 and turned upside down the WiFi connectivity for small MCU. They have been left relatively to no competition from the big Western chip makers who couldn’t match their aggressive pricing, but later there was semi successful competition from Realtek and now there is another competitor who is focused on low cost IoT audio applications but their chip is quite good for general purpose WiFi stuff also. The RDA5981 is based on Cortex-M4 inside

  • running at 160Mhz
  •  160KB SRAM
  • 8MB PSRAM
  • 4MB Flash
  • build in USB 2.0 host interface allow USB devices to be connected to the module directly which is advantage toward Espressif chips
  • Support Bluetooth 2.1 EDR + BLE4.2
  • SDMMC interface
  • 2x 10bit ADCs
  • SIDO x1, I2C x1, I2S x2, PWM x8, IR, SPI x4, UART x2, GPIO with interrupts x14
  • operating temperature -30+80C

According to the PR message their focus is voice recognition / audio play and they shipped already 200 Millions of these chips ин 2016. Looking at the features above they can be used for other IoT applications as well if their SDK is easy enough to use by maker community. The question is will be they smart enough to be more user friendly as ESP.

I check their web and even to download their datasheet they require registration :). I understand this as – we hide our product info from our potential customers as we do not want they to evaluate our chips. These registrations beside pissing off potential customers do not hide anything from their competitors as they would easily register with fake info and get them anyway, but obvious this is the way most Chinese companies work.

EDIT 10-01-2018: There is actually GitHub repo with the datsheet, so their web may be not updated!

New Product in stock MOD-WIFI-AR9271 libre drivers and firmware WiFi dongle

MOD-WIFI-AR9271-2

AR9721 chipset is the only one on the market with completely open source linux drivers and firmware, this make it WiFi chipset of choice for people who respect their freedom.

We have MOD-WIFI-AR9721-ANT for quite some time and it’s very popular item, but the 200mm antenna make it not quite small. Now we add to our web shop the version without external antenna. It’s with 85 x 25 x 10 mm dimension and have same working distance as the external antenna version.

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.

First ESP32-DevKitC development kits in Europe will be in stock next week

esp32

We have good news! The first ESP32 development kits in Europe will be next week for sale in our shop.

The quantity is very limited due to the high demand Espressif still can’t fill all the orders they got, so we will got less than 100 to start with.

If your WiFi project needs to go to next level and you want WiFi +BLE in same package ESP32 is the right device for you.

The technical resources are here. Due to the limited supply we will not process orders in which basket is put more than one ESP32-DevKitC, please give chance to more people to evaluate 🙂

The price is EUR 17.00
