boards. http://sheepdogguides.com/elec/misc/esp8266/esp8266-main.htm about 8 years ago How much Flash RAM has this board? I used this to create a driveway monitor based on a vibration sensor. Added to all that is the fact that the engineers at SparkFun were thoughtful enough to include both an on/off switch (amazing how few devices out there include this---the $300 WiFi unit I mentioned above does not, meaning that you must connect/disconnect the battery from the JST socket every time you use the device, and that requires a tool unless you're willing to break a lot of fingernails) and an on-board charger for the battery (another feature almost universally omitted). I've been a tinkerer for a long time but haven't had much opportunity the last few decades due to work and family. by Member #1289307 The ESP8266 Thing Development Board breaks out all of the module's pins, and the USB-to-serial converter means you don't need any peripheral components to program the chip. I just modified it a bit to power it solely by solar power check it out: https://www.hackster.io/fablabeu/esp8266-thing-by-sparkfun second, while I had initial "no memory" problems with the I2C (BMP180) I put my findings here https://www.hackster.io/fablabeu/esp8266-sensor - hope this is of value to the community ;-). You would need to flash the ESP8266 Thing with the firmware binary to have it recognize the AT commands. Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. verified purchaser. I purchased a few of these along with a bunch of other devices (Particle Photon, NodeMCU Dev v0.9 boards, ESP8266 boards, etc.). about 6 years ago The configuration is stored in flash and once configured it will frequently wake up momentarily to check sensors for leaks with deep sleep inbetween. verified purchaser. Is it possible to make posts to a server? I use these things to take data in the field and report back via WiFi. We need to make sure it has secure access to this board so just not anyone can shut down or reset these systems. If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. verified purchaser. If you're using USB, you can probably expect around 500mA (minus a little bit for whatever the ESP8266 is pulling). replied on December 8, 2015: about 7 years ago In this guide, we show you how to combine some simple components to remotely log temperature data, send yourself texts and control lights from afar. by Member #550112 Is it possible ? Or do i need a separate solarcharger circuit as well? This tutorial explains the circuitry driving the board, and how to get it up and running in an Arduino environment. by Member #1341501 2. by Member #218325 Research into the problem leads me to believe that this is a general issue with the ESP8266, and not a flaw in the design of the Thing, but know that it will definitely affect you. The pins are broken out to two parallel, breadboard-compatible rows. Hmm, I must say I am rather disappointed that there is no button on GPIO0 for programming and that the I2C sensors are not populated, despite being included on the schematic. The Thing is awesome so don't let my battery mishandling experience dissuade you from buying one, I would simply be remiss if I didn't share it in the hopes of preventing at least one similar incident. If so, what is recommended? Add a Capacitor (or at least space for one), about 4700f 10v or so to stabilize a solar panel and a place where a 10K NTC thermistor can be added to the board for battery temperature measurement (the 73871 already supports this). When you hook up a serial terminal, all you get is garbage. when programming from Arduino, have a wire in the two holes to connect the trace, or use a jumper, SparkFun ESP8266 Thing WRL-13231 $18.50 49 I do three things to make it work. The only hiccup was the garbled data sent to the serial monitor which was solved by cutting the tracks at the back of the PCB and putting in jumpers for uploading. I was logging data by 10pm, In that 2 hour span I at dinner, watched TV with the kiddos and conversed with the wife. The power switch is very flimsy and broke after a couple of weeks. I'm looking for numbers in the 50s, and it spikes 50% - 75% of the time to 430 of 1023. I am having the toughest time trying to get my ESP8266 Thing to connect to my wifi network. This is a great board for IoT applications. by Member #307284 What kind of battery could I use with the ESP8266? I tried mixing and matching the statement into the code but could never get it to compile I tried both NodeMCU and Arduino and both work. verified purchaser. The only request I would have if this upgraded would be to add more memory to allow OTA updates. This skill defines how difficult the soldering is on a particular product. USB and LiPo connectors at the top of the board provide power controlled by the nearby ON/OFF switch. Got it working with example sketches very easy. However, I really wish there was a pin for VUSB so I didn't have to deal with a USB connector if I didn't want to. Works great overall, thanks! Much more reliable and stable than the NodeMCU stuff. (Using it for a touchscreen WiFi clock + bedside controller for Magic-Home WiFi lights -- kind of a DIY Chumby, if anyone remembers those). Super easy and it all gets posted to data.sparkfun.com for free, allowing me to check my garage door position and garage temperature from anywhere in the world that I have an internet connection. Add a coaxial power plug for attaching the solar cell. I've been working with musicians and dancers for a number of years developing wearable motion tracking devices. It is tied to ground via a 10K resister but doesn't appear on any of the headers. 1. Yeah, FTDI is one of those things that is nice, but would add $5-10 to the board. In a future revision, it would be nice to have the XPD (deep sleep) pin run over to the header supplied for the DTR/RST connection. Used the ESP8266 Thing to interface with sensors and to post data to a MySQL database. Ok found the problem for the bad ADC reading. Finally got my Thing up and running. Minor speed bumps: In Arduino mode, it is a 32-bit processor. -------------------- Tech Support Tips/Troubleshooting/Common Issues --------------------. FTDI on board would be nice if you can do it at this price-point, but you've got the pin-out in the right order on the side so it's easy enough to connect the FTDI Basic- good thinking. Is it possible to toggle a relay with this? I don't think it's all that important in 99% of applications. Please use the link in the banner above, to get started with posting a topic in our forums. For some reason, I could never get a serial connection to this even by following the guide. about 8 years ago I got home from work at 8pm. See all skill levels. by Member #451162 Now the Thing has stopped working. Testing this with our engineer's iOS v10.11 EL Capitan, there were no issues compiling. For instance if I want to mount the board in a case and want to switch the power on/off without opening the case. Looking over the board and the schematics it doesn't look like GPIO15 is brought anywhere. Just click on the icons, download the file (s) and print them on your 3D printer. Specification Checks. about 7 years ago Here are the things I'd do to turn this into the perfect Solar development/deployment board: Put an FTDI chip on it and integrate to the USB connector. I removed D5 and replaced it with a short. Do I need to buy an antenna? The converter does need a DTR line in addition to the RX and TX pins. That being said, if you take a look at the example in the Switch Basics tutorial, you should be able to get a good idea of how to use a switch to cut power to the board. Found out after some frustration to get Onewire working you need to get the modified onewire.h file off the esp8266 arduino github respository (https://github.com/esp8266/Arduino). I even tried 0.4.5 with no success. about 8 years ago :) https://www.hackster.io/fablabeu/esp8266-thing-by-sparkfun-982bc6. I have two in house servers that we need to be able to shut down when lighting storms are approaching then boot back up after they have passed. verified purchaser. Hi, Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. Eventually figured everything out, and the information was there. (If you look at the schematics for the ESP8266 Thing, there are no breakout pins on the board to attach a power switch.). the chip takes some time to return to ambient (15 minutes or so) after handling, a lot longer after soldering. The LuMini 8x8 Matrix (APA102-2020) are the highest resolution LED matrix available. A challenge may be how to store the credentials for reboots. This board comes so close to what I want that it's slightly painful that it falls just a little bit short. And, yes, every GPIO has PWM-capabilities -- assuming your using the Arduino addon. That said, I still managed to squeeze in a couple of sensors, a display, and pushbuttons with just enough GPIO. Advertising.

See this section of the hookup guide for more info. Which is to say, an esp8266 module with a few GPIO pins that can share a power input with a pico/femtobuck without having to have a separate regulator. Tags World of tanks for CNC (WOT) add to list. UPDATE: tutorial to address EXACTLY what I am trying to do (power Thing on solar power) yey! Other than unsoldering the currently embedded switch and soldering an external switch to it, I don't see an easy solution. I uploaded to the "Thing" the example sketch "AP Web Server" with success. SparkFun's new development board for the ESP8266 breaks out all of the module's pins, and comes equipped with a LiPo charger, power supply, and all of the other supporting circuitry it requires. ), about 2 years ago Using the Sparkfun FTDI basic breakout 3.3V. That's why in the examples one of the setup lines is wifi.disconnect(); https://github.com/esp8266/arduino to program via Arduino IDE. I believe that a 1000mAh battery will last longer than a year between charges.
