Most of the off-the-shelf boards are really meant as development boards, thus too few or too many options depending on target market.
So unless you are literally out of your garage, when going to a commercialized product it might be better to roll your own circuit with the MCU, WiFi and any logic shifting integrated into a smaller customised layout.
Oh yes, absolutely. Weāre just not that far along yet. We are merely looking for a easy to replicate prototype to widen our field testing, which is why weāre still looking for off the shelf options.
Iāve seen an Arduino Mega board with integrated ESP (attached to serial port) on one board. They are not very cheap (think 25 bucks), but they look like a nice board to develop stuff on. Itās this: http://www.ebay.com/itm/222305385421 thing
You can set the connections with jumpers. E.g. wether USB<> Serial is attached to Arduino or ESP or something else. Iām hoping Iāll receive this soon for testing. Looks likes a very nice all-in-one solution for developing. Only thing missing is an Ethernet port integrated
Iām using Blink on a wemos D1 mini with no problems. I would like to use Blynk on my Arduino Uno board with w51000 shield for Wifi connection, seems to a bit harder to do. Any help doing this would be great! Thanks!
The DigiStump Oak can be utilized with the Arduino IDE. It has the WiFi you want and DigiStump has a Blynk library included with the Oak Arduino libraries.
The current level of the firmware has stabilized the WiFi connection and mine has been sending me Temp + Humidity data via Blynk for about 15 days since I last updated everything.
DigiStump has both 3.3v Relay shield and a level Shifter 3.3 to 5V shield to facillitate interfacing to 5 V devices. The Oak accepts 5 V in and provides Vin and 3.3V Vcc outputs. DigiSTump Oak or cruise the Wiki or the forums: [Forums]
I have used virtual pins, read analog in, virtual LEDs for status etc in controlling a Hi Fi remotely via Android app. The Oak is 1/3 the size of the UNO but the shifter shield in a bit larger than the Oak.
Other shields are available.
Certainly meets many of your needs as a rapid functional prototype candidate. Fairly cheap too.
So far itās a nice board, but I already bricked it by f-king up the bootloader ā¦ when it worked, it worked fine, but ESP as a shield had a high latency when connecting (450ms or so).
I donāt know. It gives back āInvalid signatureā when I try to load a new bootloader onto it (with another Mega2560 as ISP). Iām trying to find out if I can load a Sketch onto it wthout the bootloader, so if you got any bright ideas ā¦ Iām at a loss at this moment.
Please read through the last few posts above, and their relevant linksā¦
