I got one of these to help my esp32 weather station survive the Canadian Winter. So far its managing the short days and cold temps very well.

Support from the developer has been top notch, in fact one of the best, if not the best, support experiences I've had in several years.

Would highly recommend this product.

Great product

Great quality product, works as expected! I'll buy another one soon! Jasper kindly answered to all my doubts and questions, thank you very much!

Thanks Federico

Just go for it!

The board is plug and play and it does exactly what it should! Jasper is also very helpful, he answered all my questions almost instantly and shipped my order super fast (it took just 4 days for it to arrive in France with the cheapest shipping option and the weekend in between). I'll definitely reorder more if I expand my project!

Exceeds my expectations

My project entailed a small greenhouse. Even in early Spring, the temperature inside can reach > 40°C on sunny days and I didn't want to arrive home at a collection of withered seedlings. So it would have to open and close automatically. This solar energy harvester is perfect for the job because there is abundant energy when it is most needed: when the sun shines.

I paired it to a cheap solar cell that I got off one of these cheap Chinese solar lamps looking like a rock that I had lying around. I paired it to a modified Arduino Pro Mini (which only uses 5 µA in deep sleep), and drive a small electric motor with it through an Adafruit DRV8833 motor controller.

The whole setup works better than I could dream of. The lithium capacitor holds enough charge for tens of open/close actions. And at 5 µA it can go for weeks without light. Even on overcast days it is able to charge. It's an incredible device.

I purchased version 2 and after living for a month in my window sill to test it out, the buck converter mysteriously died when I was at the point of integrating it into my project. Jasper didn't waste any time and swapped it for a new one without hassle. Bonus: I got a version 3 instead which can deliver a higher current.

Highly recommended!

Perfect for my Project!

I just received it today and put it together with my project: https://www.tindie.com/products/informatic0re/thread-sensor-tag/
It is the perfect solution! It is already running and I will run it for a while to see how it goes. I assume the battery will be fully charged at the end and the device will run forever. Super nice!

I love the Stickers which say "HACKED"!! Thanks for this little board! I probably use it in the future in a new version of my project (but I think I will use your design, not the Board due to size restrictions)

Thanks Mirko for the good review

Patrick | Dec. 9, 2022

Great product

Does exactly what it is supposed to do. I'm using it in my LoRa Hackaday project here: https://hackaday.io/project/187574-ill-sleep-when-im-dead

Thanks for the poisitive review Patrick

Excellent product!

I ordered this board and two 250F lithium-ion capacitors. They arrived promptly by Netherlands Post. As a novice in electronics and soldering, I was initially unable to get it to work. Jasper answered my questions and suggested that I may have damaged the board. I realize that I had several wrong assumptions. He offered to send me a replacement at a significant discount. I later realized that I had soldered the headers incorrectly. After re-soldering, and after better understanding how the board works, I have successfully used it to power a Raspberry Pi Pico. I am very happy with what I have learned about powering my project using energy harvesting.

I am writing up some of my learning experiences at the Hackaday website https://hackaday.io/project/187262-the-aemlic-solar-harvesting-board-my-journey

My conclusion about soldering: Solder at the right temperature

Superb product, fast delivery and outstanding support!

Bought AEMLIC kit and a solo board and it promptly arrived within a few days (together with a small gift! - THANK YOU Jasper! :) ). During the waiting time Jasper didn't hesitate a minute to answer my questions (and there were many! ;) ).

Professionally made product and a professional service.

I highly recommend it and I'm looking forward to more great products from Jasper.

Thank you, Jasper! :)

Maxime | April 8, 2022

Perfect !

Quick deliver, everything looks great, impatient to test it ! And thanks for the small breadboard ;)

Response from Jasper Sikken | May 23, 2022

Thank you Maxime!

Tsuyoshi | Feb. 7, 2022

Thank you, you have saved me time and money.

I didn't have enough time to make it myself, so I am grateful to have found just the right product.
I hope to see more works using lithium ion capacitors.

Response from Jasper Sikken | March 18, 2022

Thank you for the positive review! Please let me know if you have questions.

Malcolm | Nov. 12, 2021

A useful little board.

Worked as expected and much better than other energy harvesters I have used in the past. Thanks for creating this and for writing the articles on supercapacitor leakage. It has either saved me a lot of time in prototyping my own board, or money in buying one of the official dev kits.

Response from Jasper Sikken | Nov. 12, 2021

Thank you

James | Oct. 23, 2021

Fantastic!

A great device and rapid shipping. I've previously purchased the AEMLION & AEMSUCA, but this AEMLIC is my favourite. I bought the kit and have it charging nicely with the solar cell stuck to the inside of my window in the cloudy UK! I have it powering a barebones atmega328p clocked at 4 MHz on the internal oscillator to run at 2.2 V, sleeping with the arduino rocketscream library for a sensor project. Jasper - any recommendations for measuring the voltage on the capacitor with a microcontroller without damaging the AEM10941 chip? Thanks!

Response from Jasper Sikken | Oct. 24, 2021

Hi James, thanks for the positive review! You need to divide the 2.5-3.8V using a voltage divider made by two resistors. If total resistance is more than 2 megaohms then the bias current is not so significant (1uA), so you could select two 1Mohm resistors to divide by two. If you want no bias current at all then you could use a mosfet to open the current path to ground.

Great product

Great small board for solar harvesting. I'm using this board in some of my LoRaWAN projects.
Even with the cheapest shipping method, the board arrives within a few days. Last order was made on a Sunday and was delivered on Friday in Switzerland.

Response from Jasper Sikken | Aug. 17, 2021

Thank you Matias!

Joseph | June 8, 2021

Very happy!

Couldn't have been better. Seller was responsive and quick to resolve any issues. Board was great, too. Thanks!

Response from Jasper Sikken | Aug. 17, 2021

Thank you Joseph!

Craig | May 20, 2021

Fantastic Product and Service

Very well made device! As advertised, it's even able to harvest solar power indoors. As a learner it has made efficient solar harvesting much simpler and I'm looking forward to trying some ideas out for it. My purchase was lost or delayed so Jasper very kindly and very quickly sent me another one free of charge!

Highly recommend if you're looking to efficiently harvest solar power with li-on caps :) Thanks Jasper!

Response from Jasper Sikken | May 22, 2021

Thank you for 5 stars! I made the silly mistake not writing the city on the envelope. Ofcourse I resend another one free of charge. Thanks Craig

Josh | May 16, 2021

Good quality and price

For 18650 discharger

Very good quality discharger. Exactly what I was looking for. .

Taeho | Feb. 14, 2021

Never received products

Well, I chose a cheapest shipping method and contacted the seller but somehow the package is gone in somewhere.
Maybe it is because of the covid19..maybe. Anyway, if you are located outside EU, make sure you choose trackable shipping method.
Otherwise, seller will not take responsible for the missing package.
hope this helps you

Response from Jasper Sikken | Feb. 14, 2021

Hi Taeho,
I am sad you rated my product with a single star because it did not arrive very quickly. You selected regular mail without tracking and after 2 weeks already expected it to arrive on the other side of the world. Within 1 day I reponded to your enquiry and after that you have not contacted me anymore. I am a very responsible seller, I sometimes resend a new one for free. I suggest you wait forever.

P | Dec. 30, 2020

great product

Arrived verry fast. Not tested yet but I expect that it works as described and I hope that it can drive a solar powered lora node.

Response from Jasper Sikken | Dec. 30, 2020

Thanks for the 5 stars! Please let me know if you have any questions, I am happy to help!

Erico | Oct. 8, 2020

Product, shipping and docs

Everything was perfect! I regret to say that due a error made by ME I was only able to use the board for 3 days. I disassembled my fist circuit in the proto board to check the battery voltage and then I mistakenly inverted where was the place of the battery with the place of the solar painel, conclusion, the board chip died and also the battery. Funny and sad at the same time, LOL.

Rajeev | July 10, 2020

Just what I was looking for...

Received the package in perfect condition. Easy to set up the board and already got my test system up and running within a few minutes.
